Frequently Asked Questions

How do I Choose the Correct MWCO Filter?

For proteins, it is recommended that the selected MWCO is three to six times smaller than the molecular weight of the solute being retained. If flow rate is a consideration, choose a membrane with an MWCO at the lower end of this range (3X). However, if the main concern is retention, choose a tighter membrane (6X). As different manufacturers use different molecules to define the MWCO of their membranes, it is important to perform pilot experiments to verify membrane performance in a particular application.

Can I Reuse MWCO Centrifugal Filters?

Although not ideal, MWCO filters can be reused if they don’t clog and provided that the proper cleaning protocol is followed. If there is drastic protein loss or concentration starts to take an unexpected long time, the filter is clogged. Despite this fact, they should be discarded after a maximum of three uses. These filters may start to leak after being used two to three times.
