Sterilization - Fact#04

Post by Admin on Fri Sep 25, 2015 10:33 pm

FILTRATION

Filtration is a great way of quickly sterilizing solutions without heating. Filters, of course, work by passing the solution through a filter with a pore diameter that is too small for microbes to pass through.

Filters can be glass funnels made from heat-fused glass particles or, more commonly these days, membrane filters made from cellulose esters. For removal of bacteria, filters with an average pore diameter of 0.2um is normally used.

But remember, viruses and phage can pass through these filters so filtration is not a good option if these are a concern.
