Major Uses for Ultrafiltration Solute concentration Solute fractionation or clarification Solute desalting or purification Ultrafiltration is a convective process that uses anisotropic semipermeable membranes to separate macromolecular species and solvents primarily on the basis of size. It is particularly appropriate for the concentration of macromolecules and can also be used to purify molecular species or for solvent exchange. Ultrafiltration is a gentle, non denaturing method that is more efficient and flexible than alternative processes Typical applications for ultrafiltration...

Membrane Performance Characteristics Sartorius offers an extended range of membranes to cover the great majority of ultrafiltration requirements. The following is a guide to selecting the most appropriate membranes according to their typical performance characteristics. Please note however, that membrane behavior and ultimate performance, largely depends on the specific characteristics of the solution being processed. Sartorius recommends that users experiment with alternative membranes in order to optimise their process performance. Polyethersulfone (PES) This is a low binding membrane...

Membrane Selection Guide The advanced designs and low adsorption materials that characterise Sartorius products, offer a unique combination of faster processing speeds and higher recovery of the concentrated sample. Providing that the appropriate device size and membrane cut-off is selected, Sartorius products will typically yield recoveries of the concentrated sample in excess of 90% when the starting sample contains over 0.1 mg/mL of the solute of interest. The majority of any loss is caused by non specific binding both to the membrane surface and to exposed binding sites on the plastic...

Choice of membranes 0.4–2 mL samples The Vivaspin® 2 bridges the gap between the 500 μL and 4 mL centrifugal concentrators. This device combines the speed of the classic Vivaspin® products with low internal surface and membrane area for superior recoveries from very dilute solutions. Also unique to the Vivaspin® 2, is the choice of directly pipetting the concentrate from the dead stop pocket built into the bottom of the concen trator, or alternatively reverse spinning into the concentrate recovery cap which can then be sealed for storage. Both methods result in near total concentrate...
