Question

Membrane filtration, typically using a 0.22 µm filter, is primarily used for sterilising:
Options
A Metal instruments and glassware.
B Liquids containing heat-sensitive compounds like serum or enzymes.
Correct Answer
C All types of biological waste, including prions.
D Surfaces contaminated with vegetative bacteria.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Membrane filtration is specifically mentioned for sterilising heat-sensitive liquids because it physically removes bacteria and fungi without heat. Viruses, however, can pass through.

Hint

Consider the main advantage of filtration over heat-based methods.
