The molecular weight cut-off
is such that the membrane will pass monovalent salts like sodium chloride, yet retain divalent salts, proteins, and sugars.
duty/standby ultrafiltration modules designed for a molecular weight cut-off
(mwco) of 10 kilodaltons (kda), c.
The PESU membrane inside the Sartocon assemblies is available in several sizes and 10-300 KDa molecular weight cut-offs
and are suitable for use in broad pH and temperature ranges.
