Tube Pins Overview

Tube Pins are stainless steel pins that are fixed inside tubes (cannulas) to provide greater strength to fragile small diameter pins.  These tubes rest upon the lower float plate.

The Tube pins vary in diameter (from 0.229 mm to 0.914 mm), they also vary in the total length of the pin (from 33 mm to 62.2 mm) and the length of the exposed pin (from 12 mm to 17 mm to 30 mm to 41.5 mm) long. The exposed length terminology is used to define how far the pin is able to extend below the bottom float plate. The 12 mm long exposed length pins are used on robots with “Z” limitations and the 30 mm and 41.5 mm long exposed length pins are used when delivering to or from the bottom of a deep well plate. For all other applications use either the standard 17 mm FP_ or FP_N series pins.

The volume of liquid transferred on a pin will vary with the diameter of the pin, the depth to which it is submerged into a liquid, and the speed the pin is withdrawn from the liquid.  Also, the surface tension of both the pin and the liquid will affect the volume transferred.

The Tube pins can be modified by cutting a very small precise slot in the tip of the pin which fills and drains by capillary action.  The advantage of the slot pin is that if there are different volumes in the source wells (if the plate has been cherry-picked many times) the slot pin will be less affected by the different volumes in the source plate.  Slot pins because of filling by capillary action are able to make transfers from very small liquid volumes in source plates.  Slot pins also yield greater precision.  The volume in the slot of a tube pin varies from 6 nL to 2,000 nL.

Both the Tube style pins and the E-clip pins can be coated with a hydrophobic layer to reduce non-specific binding to the pin.

Hydrophobic Coating Overview

Many of our customers are concerned about the non-specific binding of proteins and lipids or lipo-proteins to robotic pins.  One way of reducing this non-specific binding is the /ah Surface Energy Modification System.

V&P Scientific is using the /ah System to alter the wetting characteristics of the pins. Simply put, a pin that is not wetted by a particular liquid has a lower critical surface tension than the surface tension of the liquid. A pin not wetted by the particular liquid is often said to “repel” the liquid, and the liquid beads up on the non-wetted pin. Conversely, if the particular liquid wets the pin, a drop will spread out on the pin surface.

Our hydrophobic coated pins are very useful in handling solutions with proteins or lipids that may stick to naked stainless steel.  See this page for a more thorough discussion of hydrophobicity and surface tension.

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

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.
