In the dialysis method, the sample in question is separated from the “precipitant” by a semi-permeable membrane which allows small reagent molecules to pass but prevents biological macromolecules from crossing the membrane.1-3 Dialysis Buttons are injection molded from polystyrene, and are the size of a small button. The sample is placed in this chamber so as to create a slight dome of liquid at the top of the button. A dialysis membrane is placed over the top of the button/sample and is held in place with an O-ring. The O-ring is held in place by a groove in the Dialysis Button. Dialysis Buttons are supplied with O-rings. The 5 µl to 100 µl sized dialysis buttons have an approximate overall height of 6 mm, an approximate outside diameter of 10 mm without an O-ring in place, and an approximate diameter of 12 mm with an O-ring in place. The 200 µl and 350 µl sized dialysis buttons have an approximate overall height of 8 mm, an approximate outside diameter of 15 mm without an O-ring in place, and an approximate diameter of 17 mm with an O-ring in place. Each package of dialysis buttons includes a plastic golf tee shaped applicator to assist with applying a dialysis membrane to the button and securing with the supplied o-ring.
