eating Blocks For Microplates & Vials

     
         
 

V&P Scientific builds robust, low-profile heating blocks that enable heating and stirring in microplate. They 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. Commercially available heating blocks are not compatible with magnetic stirring because they position the samples too far above the stir deck or are not compatible with robotic workstations.


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.


All Heating Blocks listed above can be made with features that allow computer control of the temperature variables. For more information, please contact V&P Scientific technical personnel by phone or email (sales@vp-scientific.com).

   
         
 

200C Heating Blocks

     
 

VP 741AZ Series

     
 

The VP 741AZ Series Heating Block provides more consistent heating (+/- 1°C) than standard heat blocks, allows heating to high temperatures (up to 200°C). 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 (microplate dimensions – 127.76mm x 85.48mm) made of Mica (VP 581B-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. The Mica is safety rated by UL laboratories as UL 94VO.


The VP 741AW-R-MB can be used to heat standard microplates, deep well 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 as Thermocouples are. This becomes important when heating and stirring simultaneously (see below).

200C Heating Blocks

     
 

The VP 743 Series Block Heater 25C to 200C

     
 

The VP 743 Series 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 200C. The temperature is determined +/- 1C by a Watlow controller and an RTD. 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 495 mm long by 112 mm wide and 54 mm tall. With the lid in place it is 61 mm tall. The three cavities of the heat block are separated by an aluminum web. Each cavity is 128 mm long, 86 mm wide and 35 mm deep. The bottom of the wells or vials are only 19 mm above the stir deck for maximum magnetic coupling. The VP 743 was designed to be used with the VP 710E-3 series Alligator Tumble Stirrers.

Graphite Heat Blocks

     
 

V&P Scientific now offers graphite heat blocks for use with magnetic stirring. Heat blocks are generally made from blocks of aluminum that causes an eddy current when placed near a spinning magnetic field such as a magnetic stirrer. The eddy current will cause additional drag which in turn will reduce the life and/or damage the motor of a magnetic stirrer. It will also generate heat within the aluminum block itself. The exact amount generated is a function of aluminum mass, strength of the magnet, proximity of the magnet. Graphite is an excellent heat conductor. Because graphite is non-metallic, there is not an eddy current produced when used with V&P’s magnetic stirrers such as Tumble, Vortex, or Conventional stirring.

   
         
 

VP 741GZ-64

     
 

The VP 741GZ-64 is a Watlow controlled graphite heat block for 50ml conical tubes with 64 positions. It was designed to go onto a Tecan EVO platform and used in conjunction with V&P’s magnetic tumble stirrer. The block is 13 x 13 inches and 7 inches tall. Due to z-height limitations, a square cutout was made to the Tecan deck for the block to sit lower and allow for the Tecan grippers to remove and add tubes to the graphite block. The graphite block sat on a support table that had a tumble stirrer mounted directly underneath the graphite block. The block uses a Watlow PID controller, with a temperature range from 25 to 120C, and runs on 120V. A 220V version, VP 741GZ-64CE is also available.

   
 

When the graphite heat block is used in conjunction with V&P’s tumble stirrer, it allows for high-throughput mixing of 50ml conical tubes while heated. The setup was designed to automate Adaptive Laboratory Evolution on a Tecan Evo. The process required each culture to be aerated for maximum growth while incubated and sampled every 15 minutes. Click Here for more information regarding this application.

   
 


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 a VP 710 Series Tumble Stirrer into a protective cabinet called a StirBase.

VP 741I6A

     
 

The VP 741I6A will get the fastest heat transfer from our heating blocks to the wells of a non-skirted deep well microplate without using a messy liquid heat conductor. Most deep well microplates have a “skirt” that acts as an air insulator which prevents heat transfer. Non skirted plates such as the AbGene #AB-0661 is optimal for heat to transfer. 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 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 VP741BZ Series Heat Blocks 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.

Eddy currents are currents induced in conductors like aluminum by changing magnetic fields. 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 specially design our inserts and heat blocks to minimize the Eddy current phenomena without affecting the heat block or insert’s ability to transfer heat. Our unique 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.

     
         
 

VP 416-ALB-8

     
 

The VP 416-ALB-8 is a Heat Block Insert with SBS microplate dimensions that fits inside our standard VP 741 through VP 744 Heat Block series.

The 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.


The VP 416-ALB-8 heat block insert has 8 flat bottom wells, each 25 mm in diameter. The insert comes with a lid that has holes above each well for more even heating while allowing samples to be added or removed while the lid is still in place.

The Eddy Current defeating design reduces the load on the magnetic stirrer’s motor and also reduces the temperature that the aluminum block is heated up to. This latter phenomena is important in applications where the temperature of the heat block needs to be less than 40°C.


The heat block insert has 48 round bottom wells each 12 mm in diameter by 20.7 mm deep.




The photo to the right shows an assortment of vials, tubes, and bottles that the VP 416-ALB-48 will accommodate.

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 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.

ustom 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. Please contact V&P Scientific technical personnel by phone or email (sales@vp-scientific.com) for any custom heating blocks.
