Question

Andreasen pipette method is used over the size range of ………

• A. 0.01–0.1 µm
• B. 0.1–300 µm
• C. 0.01–50 µm
• D. 0.01–1000 µm

Hint:

Andreasen pipette = sedimentation method for 0.1–300 µm particles.

Answer 1

The Correct Option is B

The Andreasen pipette method is used to determine the particle size distribution in suspensions within the 0.1–300 µm range. It works on the sedimentation principle governed by Stoke’s Law.
