Which of the Following is NOT a Feature Associated with Filtration

Question

Which of the following is NOT a feature associated with filtration?
A) nitrocellulose or plastic membrane filters
B) sterilization of heat-sensitive materials
C) varying thicknesses of membrane filters used
D) use of HEPA filters to filter air
E) ability of some filters to trap viruses and proteins

Accepted Answer

Filtration involves using membrane filters, often made of nitrocellulose or plastic, for various applications including sterilization of heat-sensitive materials, air filtration through HEPA filters, and trapping very small particles like viruses and proteins. The thickness of membrane filters does not vary significantly for these purposes; instead, pore size is the critical variable that determines what the filter can trap.
