Diacon 0.5ml Capacity Dialyser

 

Dialysis has been a useful separation technique for laboratories for many years. Swissci aims to bring easy to use dialysis solutions to the users who find this technique applicable to their workflow. For example in proteomics users can employ these products to separate proteins from compounds that include reducing agents, buffer salts and preservatives without the need to disturb the valuable protein complex being studied.


Diacon is ideal for gentle and efficient desalting of protein from small yield solutions of up to 0.5ml. Sample solution is manually pipetted into the device which is then held upright in the dialysate via the floating rack provided. The floating rack ensures the membrane is always in contact with the dialysate, allowing for dialysis to occur. The volume of dialysate can be as large as desired; the larger the volume, the larger the concentration differential and therefore a faster rate of diffusion occurs, optimizing dialysis.


Dialysis is recommended for 2-3 hours and then change the dialysis buffer leaving for another 2-3 hours. A third dialysis can be carried out if necessary. The Swissci Diacon employ specially selected regenerated cellulose membranes.
