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
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

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.

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

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.
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.
