Clutch Drive Bubble Paddle Reservoir

     
 


The unique feature of the Bubble Paddle Reservoirs is their exclusive design that eliminates "fall out zones" where particulates fall out of solution that are so prevalent with other mixing reservoirs. The Bubble Paddle Reservoirs are the only method that gives uniform suspensions of dense particulates such as Yettrium oxide SPA beads (from Amersham/GE Health Care). 

Endorsement

Here is what one of our customers at a major Pharmaceutical company had to say about our 384 Bubble Paddle Reservoir system (VP 768B & VP 755C-384C) "The reservoir is really the best thing that I have found for YSi SPA beads which immediately fall out of solution when not mixed" ..... The bubble paddle is essential for YSi beads." 

 

A clutch drive bubble paddle reservoir was used in the following experiment, "A New Purification Method for DNA Sequencing Reactions".

The  newest of the Bubble Paddle Reservoirs does not require a Magnetic Alligator Tumble Stirrer.  They are powered directly by small electric motors through a unique magnetic clutch system that we designed.  This magnetic clutch powers the Bubble Paddle right through the wall of the reservoir.  Just another innovation from the Engineers at V&P to facilitate your robotic or manual dispensing of cells and beads using  4,  8, 96 or 384 channel pipettor. 

We recently received a patent on both the Bubble Paddle Stirrers and the Magnetic Clutch method of powering the system  (US Patent #6,461,034) and European Patent # 1,314,471.

The advantage of the Magnetic Clutch Bubble Paddle Reservoirs over the Magnetic Alligator Tumble Bubble Paddle Reservoirs  is that they  are more economical and the drive system has a smaller footprint.   Both have the unique ability to stir suspensions even as the pipet tips remove the cells or beads from the bottom of the reservoir.  This, coupled with the very small dead volume in the bottom of the reservoir, makes this system uniquely suited to resuspending particulate specimens during the pipetting operation.  The magnetic clutch and motor are very powerful as they will stir honey at 4 degrees C.   To stir 4 or more reservoirs at the same time, we recommend you use the Tumble Bubble Paddle Reservoirs in conjunction with a  Magnetic Alligator Tumble Stirrer.  If you are only stirring 1 to 3 reservoirs, one of the Magnetic Clutch systems is right for you.

The reservoirs come standard in economical Delrin (VP 756C-1) and in autoclaveable Polypropylene (VP 756C-1P).   They can also be provided in  PTFE or coated aluminum, depending on your application.

  Continuous Filling

     
 


The photo to the right illustrates our solution for long pipetting runs requiring large volumes of  suspensions.  The VP 756C-1 reservoir is simply fitted with inlet and outlet nipples connected to a large stirred reservoir via a peristaltic pump (VP 560).  In this system the Bubble Paddle reservoir never runs dry and never overflows.

The inlet and outlet nipple system comes in two types of reservoirs: Economical Delrin (not autoclavable) - VP 756C-1T and autoclaveable Polypropylene - VP 756C-1PT

 
 



  Stirred Cell

     
 


VP 756C-1PD

     
 


The Bubble Paddle reservoir can also be fitted with an outlet nipple in the very bottom of the reservoir so that very fragile cells can be stirred at slow speeds and slowly removed from the reservoir via a syringe pump.  Some of our customers use this stirrer to deliver cells to a Fluorescent Automated Cell Sorter (FACS) machine.

VP 761M and VP 756CM-P -- Mini Bubble Paddle Stirrer

     
 
The VP 761M motor/drive unit and  VP 756CM-P reservoir are the smallest Bubble Paddle Stirrers we make (25.4 mm tall and 25.4 mm wide).  This design was implemented to accommodate the space limitations on the deck of an Innovadyne Nanodrop dispenser.   The reservoir is equipped with inlet and outlet nipples to accommodate large volume dispensing operations.  This reservoir is also available without inlet and outlet nipples as VP 756CM-P0 and with just an inlet nipple as VP 756CM-P1. 

The mini magnetic clutch Bubble Paddle is included with the reservoir (VP 756ACMFe). 

A 230 Volt CE compliant motor/drive version for the European market is also available (VP 761MCE).

YOx bead dispensing on to a glass plate is illustrated in the photo to the right.  The drops were made using the Innovadyne Nanodrop and the VP 761M/VP 756CM-P Bubble Paddle Stirrer to keep the beads suspended while the Nanodrop dispensed them.   Photo courtesy of Innovadyne.  Contact Innovadyne and refer to the following article for more information.
 

 

 

 



 
 
The Bubble Paddle Stirrer to the right was a custom one built for a customer who wanted a Mini-Bubble Paddle Stirrer with a larger reservoir.  This was easy for us to do.

  Magnetic Bead Stirrer

     
 
In order to stir magnetic beads you can not use any method that employs magnetism, magnetic drives or magnetic clutches because the beads will be attracted to them and taken out of solution.  As magnetic beads have become more popular in a variety of assays, a non-magnetic method to keep them uniformly  suspended is required.  The VP 767-2  and VP 758-3 with its' sealed drive shaft eliminates the need for magnetic clutches or drive magnets.  Problem solved!  The pipet depressions on the bottom of the reservoir also reduces the waste of these precious reagents.   The direct drive sealed bearing design is also capable of much higher torque than either of the magnetic driven machines so liquids of much greater viscosity can be stirred.  Follow this link to more information of these unique machines.  Our Magnetic Bead Stirrers vary from miniature versions that mate to the Innovadyne Nano Drop to 300 ml versions that fit on full sized robotic liquid handlers.
 
 
 



  Computer Controlled

     
 


The VP 762 incorporates a "smart" servo motor to drive the VP 756C-1 Bubble Paddle Reservoir.  This is very useful for those operations where you want to control the stirring speed and on/off functions from your robotic work station or  computer.

This motor is capable of 3500 RPM and powerful enough to convert honey into "spun honey".   The top practical speed is ~2000 RPM

 
 



  Programmable Smart Switch

     
 


Another more cost effective way to automate any of our Bubble Paddle Stirrers is to use our new Programmable Smart Switch.  Follow this link for more information.

 

 
 
 



***NEW***

VP 756CS-PTFE/VP 761S

     
 
The latest Bubble Paddle is constructed of chemical and solvent resistant PTFE.  Even the  motor housing of the VP 761S is PTFE.   The motor housing completely encapsulates the motor, protecting it from harmful fumes and vapors.  This Stirrer was designed to be chemically resistant and with the smallest dead volume possible (5 ml).  Also available in a CE compliant version (VP 761SCE). This Bubble Paddle Stirrer was designed to fit on a custom robotic platform made by Symyx Technologies.

The VP 756CS-PTFE/VP 761S is the longest Bubble Paddle stirrer (~11" long Bubble Paddle)  we have made to date.  It has 8 pick points or nodes 1.5" apart.  It holds 75 ml of solution and can stir 30 weight motor oil (420 centipoise) with ease.  It can even stir honey (10,000 centipoise) at reduced speeds.   Follow this link to more details on viscosity.

  96 Bubble Paddle Reservoir

     
 
The photo on the right illustrates an installation of a VP 763/VP 756C-96 on a Beckman Coulter Biomek FX.  We make an FXALP-FM flat mounting system that attaches to the bottom of the VP 763 and secures it to the deck.  The height of this plate mount on the  ALP is shortened so the pipets will clear the top of the VP 756C-96 reservoir and still  reach the bottom of the  reservoir.  

The VP 763/VP 756C-96 has been replaced by the VP 763B and VP 756C-96B which provides an even easier mounting mechanism, cooling/heating and refilling capabilities.

**Custom reservoirs with less height can easily be made to accommodate shorter pipet tips.

 

 
 
The photo to the right illustrates the modifications we made to the  Beckman FX ALP-PM plate holder  system to allow us to mount the VP 763B to it.

VP 756C-96BPTFE
     
 


VP 756C-96BPTFE is the latest in our line of 96 Bubble Paddle Stirrers.  This version of the Bubble Paddle Reservoir is very useful when used in conjunction with robotic 96 well pipetting systems.  You can rest assured that all the pipet tips will contain the same number of beads or cells from the beginning of the dispensing to the end with a very low dead volume.  This stirrer is designed to be fed continuously with suspensions of beads or cells through an inlet nipple and it has a fail-safe adjustable overflow weir that is connected to an outlet nipple.   In the event that the inflow exceeds the pipeting rate the excess liquid is diverted back into the source vessel or to a waste vessel. The inlet and outlet systems can also be isolated so the system can be operated as a static reservoir.  This reservoir is also available in Delrin as the VP 756C-96B.

The VP 763B and VP 763BCE motor/gear/magnetic clutch units  reservoir/motor/gear system are plumbed to be connected to a source of heated or chilled liquid to control the temperature of the reservoir.   It replaces our VP 756C-96/VP 763 which did not have these added capabilities and features.

The photo to the right shows the Bubble Paddle Stirrer attached to a FXALP-PMS to allow it to be used on a Beckman FX deck.

  384 Bubble Paddle Reservoir

     
 


This version of the Bubble Paddle Reservoir is very useful when used in conjunction with robotic 384 well pipetting systems.  You can rest assured that all the pipet tips will contain the same number of beads or cells from the beginning of the dispensing to the end with a very low dead volume.  

The photo on the right illustrates the intricate ducting in the bottom of the reservoir.  This ducting design, in conjunction with the Bubble Paddle shape is key in generating the fluid movement which keeps dense particulates suspended.  A small volume of blue dye was added to the reservoir to highlight the ducting feature.
 

 
 
 



  ***NEW***
  384 Bubble Paddle Reservoir with Heat Exchanger and Re-Circulating Reservoir
  (VP 768B & VP 755C-384C)

 
 


Our latest 384 Bubble Paddle Mixing  Reservoir was inspired by a customer that needed to chill and mix SPA beads while they were being dispensed into 384 well microplates.  They also needed to dispense large volumes so we incorporated inlet and outlet tubes with an overflow weir so SPA beads could be continuously cycled through the system with out fear they would settle out.  As deck space is always a consideration we reduced the size of the motor and overall footprint of the system (Reservoir Motor, drives and heat exchanger).   The total systems dimensions have been reduced in this new model. 

Reservoir Specifications:
147 mm long, 126 mm wide, 41 mm tall
Reservoir height = 30 mm**
Reservoir volume = 230 ml
Dead volume = 35 ml (this will depend on the sample volume withdrawn)

Total system Specifications:
191 mm long, 151 mm wide, 70 mm tall (locating feature mount) 57 mm tall (flush mount)

VP 581A Adapter

     
 
The VP 581A adaptor is used on all the Bubble Paddle Stirrers to register and align the Stirrers to the workstation deck plate holders.  This a quick and convenient method of mounting the stir platforms to the deck and assuring the pipet heads will align to the pipet depressions on the stirrers.  The photo on right illustrates the VP 581A attached to VP 761A and mounted to deck of a MWG robot.
 
 


  Bead Suspension Data With 96 Bubble Paddle Reservoir

     
 


One of our customers performed an experiment to determine the uniformity of silica bead suspension (3 micron diameter, specific gravity = 1.98) in a VP 756CP-96 Bubble Paddle Reservoir.   200 ml of a bead slurry was placed into the reservoir and stirred for 2 hours.  Five samples were collected from different points in the middle and around the edges of the reservoir.  The results are plotted below.  The % CV values between the 5 sample points were less than 4.95% at each dilution.  Raw data can be found at this link.
 

Samples were taken of the same silica beads from columns 2, 5, 8 and 11 to determine if the samples were uniform throughout the reservoir.  The CV's were less than 5% within the columns and between the columns.

 

 

 


  Effects of Continuous Stirring on Suspension of Silica Beads

 
 


This same customer conducted an experiment to determine if the silica beads would remain uniformly in suspension after many hours of stirring.  A VP 756CP-96 was loaded with 5 bead pools.  Each bead pool varied in the amount of stirring time done during the pooling phase.  Pool 1 is the control pool.  Each additional pool increases the duration of stirring.  The question was whether there is any significant difference in loading performance of the 5 pools.
