Heating Blocks

     
 


Several of our customers wanted to heat as they stirred their samples.  The commercially available heating blocks are not compatible with magnetic stirring because they position the samples too far above the stir deck or they contain ferrite elements that block the magnetic flux.  We have built robust heating blocks that have a very low profile with no ferrite materials.  This design minimizes the distance from the samples to the magnetic drive thus maximizing the stirring power. 

Another advantage of our design is that we have separated the control panel from the actual heating block.  Thus the heating block is very small and easily fits into areas where space is at a premium, like the deck of a robotic workstation.

 
 
 


  100C Heating Blocks

     
 


The VP 743 Block Heater  25C to 100C

     
 


The VP 743 Block Heater  is constructed of anodized aluminum and has a lid that can be screwed into place to seal cap matts onto deep well microplates.  It is used to heat  three deep well microplates or  3 racks of glass vials from 25C to 100C.  The temperature is determined +/- 1C by a Watlow controller and a thermocouple. It requires 115 volts at 4 amps to power a 450 watt heater.  It will bring water to a boil in 45 minutes and up to 80C in 20 minutes.  The outside dimensions of the block are 49.5 cm long by 11.2 cm wide and 5.4 cm tall.  With the lid in place it is 6.1 cm tall.  The three cavities of the heat block are separated by an aluminum web.  Each cavity is 12.8 cm long, 8.6 cm wide and 3.5 cm deep.  The bottom of the wells or vials are only 1.9 cm above the stir deck for maximum magnetic coupling. The VP 743 was designed to be used with the VP 710E-2 series Alligator Tumble Stirrers.

 
 
 


The figure to the right represents the difference in temperature with time for various well locations in a microplate.  Although each location has different exposure to the heating block all three locations are within 3C of each other after 40 minutes.

An additional use for the Heating Blocks is in conjunction with our evaporation manifolds to aid in the evaporation of solvents from microplates or test tubes.

  200°C Heating Blocks

     
 

VP 741AW-R-MB

 
 


The VP 741AW-R-MB Heating Block provides more consistent heating (+/- 1°C) than standard heat blocks, allows heating to high temperatures (up to 200°C), and can be combined with stirring using one of V&P’s Tumble Stirrers. This Heating Block is constructed of anodized aluminum and has a deep chamber and lid that can be screwed into place to reach high temperatures and hold CapMats or other sealing materials in place. The Heating Block comes with a U-shaped insert that allows easy removal of standard microplates or other short labware. It also includes an SBS Adaptor Base made of 12.5 mm thick Mica that is attached to the Heating Block’s underside. This Base provides heat protection for surfaces below the Heating Block and facilitates its use on SBS-configured locations such as V&P Stirrers or robotic decks. The Mica is safety rated by UL laboratories as UL 94VO.

 
 
 


The VP 741AW-R-MB can be used to heat standard microplates, deepwell plates, PCR plates, or SBS-sized racks of tubes or vials from 25°C to 200°C. Temperature is controlled by a Watlow PID controller that uses an RTD (Resistive Thermal Device) heat sensor. RTD sensors are advantageous because they are not affected by the moving magnetic fields generated by V&P Tumble Stirrers. This becomes important when heating and stirring simultaneously (see below).

  • Outside dimensions: 18.1 cm length x 10.5 cm width x 6.8 cm height.
  • Height with lid in place: 7.42 cm
  • Dimensions of heating chamber: 12.8 cm height x 8.6 cm width x 3.5 cm depth

If stirring at the same time on one of our Tumble Stirrers, the bottoms of the wells, tubes or vials are only 1.9 cm above the stir deck for maximum magnetic coupling. If heating above 100C on a Tumble Stirrer, it is recommended that the Stirrer also be Mica heat-protected, for example, see VP 710E-2HM-1

This Heating Block is available in a 230 volt version that is CE compliant (VP 741AW-RCE-MB).

Both versions above can be made with a slightly thicker SBS Adaptor Base of 18.75 mm thickness (VP 741AW-R-MA and VP 741AW-RCE-MA) for situations in which the Heating Block needs to be raised, for example, with certain robotic plate nests.

 
 
 
 

VP 741ABW-R-MB

     
 


The VP 741ABW-R-MB is specially designed for use in combination heating and stirring. The design minimizes drag on the Tumble Stirrer motor due to Eddy currents given off by the changing magnetic field. This allows a broader range of V&P’s Stirrers, including those with less powerful motors, to be used in combination with heating.

Click here to see how the VP 741ABW-R-MB Heating Block is used on a VP 710E-2HM-1 Tumble Stirrer. Note that the SBS Mica insulating Adaptor Bases attached to the undersides of the Heating Blocks fit nicely into the SBS Mica pockets on our Tumble Stirrers.

This Heating Block is also available in a 230 volt version that is CE compliant (VP 741ABW-RCE-MB). In addition, these versions can be made with a slightly thicker SBS Adaptor Base of 18.75 mm thickness (VP 741ABW-R-MA and VP 741ABW-RCE-MA) for situations in which the Heating Block needs to be raised, for example, with certain robotic plate nests.

Several of our Heating Blocks, including the VP 741ABW-R-MB, have been made with features that allow computer control of the temperature variables. We are currently updating our computer control system and will post the features when available. However, if you are interested at any time, please contact V&P Scientific technical personnel by phone or email (sales@vp-scientific.com).

     
         
 


VP 741AJ

     
 


The VP 741AJ is a polycarbonate shell that fits around our VP 741A series heat blocks to protect laboratory personnel from the hot Heating Block. The shell can be used with temperatures up to 120°C.

 
 
     
 
         
 

VP 741BW-R-MB

     
 


The VP 741BW-R-MB Heating Block has a shallow chamber ”cut away design” so that a robotic plate handler can move PCR plates and other microplates around the deck. Like the “deep chamber” version described above, this Heating Block provides more consistent heating (+/- 1°C) than standard heat blocks, allows heating to high temperatures (up to 200°C), and can be combined with stirring using one of V&P’s Tumble Stirrers. It is constructed of anodized aluminum.

One increasingly popular use of the VP 741BW-R-MB Heating Block is in protocols involving PCR plates, for example, DNA extraction from samples, DNA cleanup after reactions, and sizing for NextGen Sequencing. The Heating Block comes with an SBS Adaptor Base made of 12.5 mm thick Mica that is attached to the Heating Block’s underside. This Base provides heat protection for surfaces below the Heating Block and facilitates its use on SBS-configured locations such as V&P Stirrers or robotic decks. The Mica is safety rated by UL laboratories as UL 94VO.

The VP 741BW-R-MB can be used to heat standard microplates, PCR plates, deepwell plates or SBS-sized racks of tubes or vials from 25°C to 200°C. Temperature is controlled by a Watlow PID controller that uses an RTD (Resistive Thermal Device) heat sensor. RTD sensors are advantageous because they are not affected by the moving magnetic fields generated by V&P Tumble Stirrers. This becomes important when heating and stirring simultaneously (see below).

  • Outside dimensions: 18.1 cm length x 10.6 cm width x 5.4 cm height
  • Dimensions of heating chamber: 12.8 cm length x 8.6 cm width x 0.6 cm depth

Heating of PCR plates or racks of tubes is greatly facilitated using V&P’s Heating Inserts such as the VP 741I6A for 96-well PCR plates or the VP 416-ALB-48 for 12 mm diameter tubes or vials. We provide a variety of Heating Inserts for various microplates and tubes to accelerate and maintain heated temperatures, and we customize Heating Inserts as needed.

If stirring at the same time on one of our Tumble Stirrers, the bottoms of the wells, tubes or vials are only 1.9 cm above the stir deck for maximum magnetic coupling. If heating above 100C on a Tumble Stirrer, it is recommended that the Stirrer also be Mica heat-protected, for example, see VP 710SM4PH

This Heating Block is available in a 230 volt version that is CE compliant VP 741BW-RCE-MB. In addition, both versions above can be made with a slightly thicker SBS Adaptor Base of 18.75 mm thickness VP 741BW-R-MA and VP 741BW-RCE-MA for situations in which the Heating Block needs to be raised, for example, with certain robotic plate nests.

Promega has incorporated one of our VP 741B version Heating Blocks as an important component in their DNA IQTM Forensic Assay. In this article, they show that the efficacy and uniformity of heating with the VP 741B version Heating Block is excellent.

*Limited with regard to magnetic stirring due to the Eddy current effect that causes drag on the Tumble Stirrer motors. These Heating Blocks should be used only with specific Stirrers. Heating Blocks labeled "Ideal" have a special design that minimizes the Eddy current effect and thus can be used with practically all V&P Stirrers (depending on stirring parameters needed).
     
 


VP 741BW-MICA with Computer Control

     
 


The VP 741BW-MICA was built with a RS 485 computer connection on the Watlow control .  All temperature variables can be controlled via computer.

 
 
     
 
 


The VP 741BW-MICA connects to the computer through RS-485 or RS-232 with included converter.

 
 
 


  Heating and Stirring

     
 


The VP 743AW-R-MB-1 Three Position 25C to 200C Block Heater

 
 

The VP 743AW-R-MB-1 replaces the VP 743A with its Mica insulation. Instead of just insulating the heating block we attach Mica insulation to the VP 710E-2HM Tumble Stirrer deck to protect it from the 200C heat. The VP 743AW-R-MB-1 uses three Mica insulation blocks to position on the VP 710E-2HM Tumble Stirrer.

The VP 743A-1RM uses an RTD probe to determine the temperature. RTD probes are not sensitive to magnetic field sweeps and therefore are preferable for magnetic stirring operations.

 
 
 

The three Mica insulation blocks on the bottom of the VP 743AW-R-MB-1 heat block.

 
 
 

The VP 743AW-R-MB-1 is used to heat three polypropylene microplates or racks of glass vials from 25C to 200C. The temperature is determined +/- 1C by a Watlow controller and a RTD temperature sensor. It requires 115 volts at 4.6 amps to power four cartridge heaters. It will bring water to a boil in 8 minutes and the block up to 200C in 15 minutes. The outside dimensions of the block including the insulation are 60.7cm long by 12.4 cm wide and 6.6 cm tall. With the lid in place it is 7.3 cm tall.

 
 
 

The three cavities of the VP 743AW-R-MB-1 heat block are separated by an aluminum web. Each cavity is 12.8 cm long, 8.6 cm wide and 3.5 cm deep. The bottom of the wells or vials are only 2.4 cm above the stir deck for maximum magnetic coupling. The VP 743AW-R-MB-1 was designed to be used with the VP 710E-2HM series Alligator Tumble Stirrer.

 
 
 

Designed to meet the high temperature requirements of chemists to heat and stir reactions the VP 743AW-R-MB-1 heat block is constructed of anodized aluminum and has a lid that can be screwed into place to seal cap mats onto deep well microplates.

The VP 743AW-R-MB-1 is also available in a 230 volt version that is CE complaint (VP 743AW-R-MB-1CE).

 
 
 


VP 741A-RM-B & VP 744MB

     
 


The VP 741A-RM-B was designed to minimize Eddy Current drag.  The advantage is that either cheaper motors can be used to spin the magnetic cylinders or that the motors will last longer because the load will be less.

 

The photo to right illustrates a VP 741A-RM-B on VP 710E-2HM-1.

 
 
     
 
     
 
 


The photo on the right illustrates the MICA heat resistant (shielding) bottom.  We have found that Moscovite MICA is a very effiecient heat barrier and we now use it on all our Tumble Stirrers that are used with heat blocks.  We also use it on the bottom of all our heat blocks as illustrated in the photos to the right.

 
 
     
 
     
 
     
 
     
 
     
 


Graphite Heat Blocks

     
 


Enviromental Express makes chemically-resistant graphite heat blocks called HotBlocks that can be used with our Tumble Stirrers to heat and stir caustic or corrosive chemicals. Because these chemicals can affect the Stirrer motor, Environmental Express has placed our VP 710C1 Tumble Stirrer into a protective cabinet called a StirBase. In the photo on the right, our Tumble Stirrer is located inside the lower black cabinet with the 54-Position HotBlock setting on top. The StirBase plus HotBlock combination is then used inside a fume hood.


Follow this link for more information about the StirBase.


We have also tested the Environmental Express 36-Position Manual HotBlock with our Tumble Stirrers by placing supporting legs under the HotBlock. This configuration can be used if the materials to be heated and stirred are not corrosive enough to require protection of the Tumble STirrer.

 

The photos to the right and videos below illustrate how a Manual HotBlock can be used with our VP 710E-2 Tumble Stirrer and our VP 710C1 Tumble Stirrer.

  Inserts for Heating Blocks

     
 


VP 741-I

     
 


One of our customers wanted to get the fastest heat transfer from our VP 741, VP 743 and VP 743A heating blocks to the wells of his deep well microplate without using a messy liquid heat conductor.  Because most deep well microplates have a "skirt" around them, it is like having a built in air insulator that prevents heat transfer.  The AbGene #AB-0661 with its 2.2 ml volume and NO skirt offers a way to solve this problem.  We developed a 5 piece aluminum heat insert (VP 741-I) to surround the  AB-0661 plate and with the VP 741 lid, completely enclose it.   The bottom plate is machined in a sculpted fashion to closely follow the outside contours of the plate bottom.   The bottom piece fits so tight it has to be pried off with a screwdriver.  The sides and end sections are held tight to the outside walls with a rubber band. 

This is a simple yet very effective solution to enhance heat transfer.

 

 

 

VP 741I6B
     
 


The VP 741I6B  is our newest aluminum heat transfer base. It was designed specifically for the AbGene (#ab093) 96 deep well microplate. It features an sbs footprint and is sculpted to closely follow the outside contours of the plate bottom. It can be used on VP 741BW-R or on commercially available dry bath heating units. Contact one of our sales staff if you require a heat transfer base for your specific plate type.

 


 


  PCR Plate Heating Inserts

     
   

VP 741I6A

     
 


The VP 741I6A heating block insert is ideal for use with the VP 741B heating block.  With the "cut away" design it provides easy access for robotic plate handlers.  Made from anodized aluminum with conical holes to match the topography of the PCR plate it provides a very efficient  transfer of heat from the heating block to the PCR plate.

 
 


  Tumble Stirrer Compatible Heat Block Inserts

     
 

Eddy currents are currents induced in conductors like aluminum. When a conductor is exposed to a rapidly rotating magnetic field (present in our Tumble Stirrers) it can cause a circulating flow of electrons or current, within the body of the conductor. These circulating eddies of current have inductance and thus induce magnetic fields. These fields can cause repulsive, attractive, propulsion and drag effects. The stronger the applied magnetic field, or the greater the electrical conductivity of the conductor, or the faster the field changes, then the greater the currents that are developed and the greater the fields produced. In the case of Tumble Stirrers with heat blocks and heat block inserts this produces additional heat in the block or insert and it also causes drag on the Tumble Stirrer motor.


We make specially designed inserts and heat blocks that that minimizes the Eddy current phenomena resulting from magnetic lines of flux passing through large masses of aluminum without affecting the heat block or insert’s ability to transfer heat. Our unique Eddy current defeating design reduces the load on the magnetic stirrer's motor and also reduces the temperature to which the aluminum insert is heated up to. This heat reduction is important in applications where the temperature of the heat insert needs to be less than 40°C.

  Heater/Chiller Recirculating Fluid Blocks

     


VP 744A

     
 


The VP 744A is a heater/chiller device which when connected to recirculating water bath can regulate the temperature of a microplate. Two hose barb nipples connect the serpentine channels in the heater/chiller to a pump and a hot or cold fluid bath. The bottom portion of the VP 744A has the same SBS dimensions as a Microplate so it will  fit into a robot deck tile and the top of the VP 744A will accommodate a Microplate.

 
 
 
The Photo to right illustrates the serpentine heating/cooling channels.
 
 
 


The photos to the right illustrate the VP 744A on a VP 710G6 Tumble Stirrer, a V&P Pin Tool Robot deck and a Mini-Trak deck.  With its open architecture, the VP 744A is well suited for robotic work station applications as it is easy for plate handlers to pick up and deliver microplates to the device.

The VP 744B-MB also has VP 581BMICA on the bottom to allow it to placed and located on deck tiles.

 
 
     
 
 


VP 745

     
 


VP 745 Heater/Chiller block for regulating the temperature of a VP 750 Bubble Paddle Stirrer.  We designed this system to fit on the deck of a Caliper Sciclone with a VP 710C1 under the deck to power the Bubble Paddle Stirrer.  Just attach to a heater/chiller bath and a pump.

 
 
     
 


  Cooling Blocks

     


VP 416-AL

     
 


Aluminum microplate to keep liquid in wells cool.

 
 


VP 581C-AL

     
 


The VP 581C-AL was designed to keep the contents of a microplate cool while on a robotic work station.  Made from block of solid aluminum 2.54 cm thick the
VP 581C-AL will keep a microplate between 7C and 10C for over 15 minutes. 

 

Follow this link to data showing the ability of the VP 581C-AL to stabilize the temperature of a 96 well microplate with 300 ul of distilled water in each well.  The VP 581C-AL were either chilled to 7.8C or -13C prior to placing on the robot deck.

 
 
     
 


  Programmable Smart Switch

     
 


Another more cost effective way to automate any of our Heating Blocks is to use our new Programmable Smart Switch VP 700.  Follow this link for more information.

 
 


  Custom Heating Blocks

     
 


We also make custom inserts for heating blocks.  The one at the right was machined so the inside of the hole matched perfectly with the round bottom of each of the different containers.  The one below incorporates various diameter holes and bottoms that conform very closely with the outside surface of the glass bottles they hold.  The circular design facilitates stirring on a conventional horizontal magnetic stirrer.
