The disposable Diaplate is a 96 well micro-dialysis plate ideal for the desalting of protein from very small volumes of up to a maximum of 3.2 µl.

The sample solution is pipetted into each of the 96 wells with up to 0.35ml dialysis solution used for exchange. The Diaplate is ANSI/SLAS 1 2004 standards providing high throughput use with robotic dispensing. Dialysis is recommended for 2-3 hours and then the dialysis buffer is changed being left for another 2-3 hours to achieve over 90% exchange. Further dialysis steps can be carried out as required. Incubation, rocking table for speed and moisture chamber for full humidification can be applied to the experiment if desired.

Each of the 96 wells has a separate regenerated cellulose membrane inside meaning no cross contamination or leakage between wells. The size of the compounds that pass through the membrane are determined by its Molecular Weight Cut Off (MWCO). The Swissci Diaplate comes as standard with a specially selected membrane that has a MWCOs of 10,000 Daltons. The Diaplate kit includes: Diaplate with 200 Micron Pressure Adhesive Spacer, 200 Micron UVP Cover Film, engraved UV Protective Cover and a sealing Paddle. Swissci W82010.
