Particulate Magnetic Clutch Suspension Systems in Reservoirs – Many Choices

V&P has developed over 30 different reservoir suspension systems for pipetting uniformly suspended beads, cells, particles, and resins into microplates of nearly every description. We have refined, perfected, and consolidated that list down to the best 26. These reservoir suspension systems are powered by motors spinning magnetic clutches and connecting through the reservoir wall to a corresponding magnetic clutch attached to one or more of our Bubble Paddles. This magnetic clutch system eliminates the need for a sealed bearing connecting the motor to the Bubble Paddle. The Magnetic clutch system works for all particulates except magnetic beads as the magnetic beads are attracted to the magnets in the clutches.

Uniformity of Suspension and Small Dead Volumes are Important

Keeping assay beads, SPA beads, glass beads, resins other particulates, and cells in homogeneous suspension while they are being pipetted to microplate wells is very important if reproducible results are to be obtained. It is also important to do this with the smallest dead volume possible when the reagents are very expensive.

The unique V&P Scientific Bubble Paddle Reservoir suspension systems (US Patent #6,461,034 & European Union Patent #1,314,471) provide a very simple and inexpensive way of accomplishing this goal. Whether you are using a 4, 8, 16, 24, 96, or 384 pipetting head, there is a magnetic clutch suspension reservoir with bubble spacing that allows a pipet tip to be inserted in the gap between bubbles. The unique contours machined into the reservoir coupled with the contours of the Bubble Paddle design results in a very vigorous upwelling current resulting in a homogeneous suspension of the particulate contents in the 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 is so prevalent with other mixing reservoirs. Also if dead volume is not an issue in your assay you can use our economical VP 756C-1PTFE  suspension reservoir powered by a  VP 761-3 Magnetic Clutch Drive Motor in conjunction with a 4, 8, or 16 pipet head for a low-cost reservoir suspension system.

Match the Particulate and Application to the Appropriate Suspension Reservoir System

There are many characteristics of your material that will affect where and how they are suspended:

  • The size of the material – is it larger than the paddle/reservoir contour gap
  • The density of the material
  • The fragility of the material
  • The speed at which it can be stirred without breakage
  • The temperature sensitivity of the material
  • The light sensitivity of the material
  • Does the reservoir need to be continuously fed

 

All of the above features are very important, and we have dealt with all of them over the course of the last 16 years that is why we say “choose your suspension system wisely before you launch a new assay protocol”.  With our large selection of Suspension Reservoirs Systems, we can help you make the best decision for your application.  We are happy to share our knowledge with you. We may be able to suggest a specific product for your application. If economy and uniformity of suspension are important to you, we have solutions for you.

Advantages of V&P Scientific’s Magnetic Clutch Suspension Reservoir Systems
  • V&P’s patented contours in the bottom of the reservoir which match the contours of the Bubble Paddles produce a vigorous upwelling current in the reservoirs to keep particulates in uniform suspension
  • The Bubble Paddles are contoured so pipet tips will fit in the gaps between the bubbles and not interfere with spinning bubble paddles
  • V&P’s patented contours in the bottom design also eliminate “fall out zones” where particulates settle out in other mixing reservoirs
  • Small footprint on Robot Deck, because it doesn’t require a large Tumble Stirrer to power the Bubble Paddles
  • Designed to fit on robot deck features to facilitate precise x and y matching to the robot pipetting system
  • Designed to be taken off the robot deck and replaced in the exact same position
  • Greatest variety of Suspension Reservoirs Systems for 1, 4, 8, 12, 16, 24, 96, and 384 pipettors

Conclusion

Coating pins will reduce the total amount of liquid transferred and also reduce the amount of non-specific binding to the stainless-steel pins. If the substance you are transferring has high non-specific binding this will be an important factor in selecting your pins.

Transfer Of Horseradish Peroxidase In Tris Buffered Saline With Pin Tools

Conclusion

Although the slots in the pin are a precise volume, the liquid that is transferred is usually more. The reason for this is due to the surface tension of the liquid causing the liquid in the slot to “bow out” thus increasing the volume of the liquid in the slot. If is important for you to transfer exactly a certain volume we can make custom slots to match the surface tension characteristics of your liquid

2. Increasing the concentration of DNA does not significantly increase the volume of Tris buffer (aqueous) transferred by both coated and uncoated FP3S500 Slot Pins.
3. Increasing the concentration of BSA (Bovine Serum Albumin) significantly decreases the volume of Tris buffer transferred by both coated and uncoated FP3S500 Slot Pins.
4. Hydrophobic coated FP3S500 Slot Pins transferred less DMSO – DNA and less Tris DNA and less Tris BSA than the uncoated FP3S500 Slot Pins.

Conclusions

1. In contrast to the FP3S500 data, increasing the concentration of DNA to .25 mg/ml does not significantly increase the volume of DMSO liquid transferred for both coated and uncoated FP1S50 Slot Pins.
2. Increasing the concentration of DNA does not significantly increase the volume of Tris buffer (aqueous) transferred by both coated and uncoated FP1S50 Slot Pins.
3. In contrast to the FP3S500 data, FP1S50 coated pins transferred about the same volume of DNA at all concentrations as did uncoated pins.
4. Both coated and uncoated FP1S50 pins transfer significantly more aqueous solution than DMSO.
5. The differences between the FP3S500 and the FP1S50 pin may be due to the different pin diameter’s effect on contact angle and therefore on the “wetting” of the pin. See the diagram on the link to / ah energy system.

Aqueous Transfer with Solid Pins

Hydrophobic coating pins will reduce the total amount of aqueous HRP liquid transferred and also reduce the amount of non-specific binding to the stainless-steel pins. If the substance you are transferring has high non-specific binding this will be an important factor in selecting your pins.

 

Pin diameter also has an effect on the degree of reduction of liquid transfer with hydrophobic coating as the smaller the diameter the less the reduction of transfer. This is most likely due to the curvature of the pin affecting the wetting contact angle

Aqueous Transfer with Slot Pins

Although the slots in the pin are a precise volume, the liquid that is transferred is usually more because of the volume carried on the sides of the pins. 

As seen with other aqueous data the amount transferred on hydrophobic coated Slot pins is less than on uncoated Solid or Slot pins. Thus Hydrophobic coating has the most effect on aqueous transfers.

Withdrawl Speeds Impact on Volume Transfer

Solid Pins More affected by Source Plate Volume

Volume Transferred For FP1 Pins (Uncoated) In 96 And 384 Formats
Volume Transferred For FP3 Pins (Uncoated) In 96 And 384 Formats

Note: Same volume (200ul for 96 Format and 74 ul for 384 Format) in recipient plates and same pin withdrawal speed for all pins. Changes to pin withdrawal speed or volume in the source plate can result in different volumes being transferred.

Transfer volumes should always be confirmed by customers for their assay conditions and automated system.
