Svedberg units

英语百科

Svedberg

A laboratory ultracentrifuge.

A svedberg unit (symbol S, sometimes Sv) is a non-SI unit for sedimentation rate. The sedimentation rate for a particle of a given size and shape measures how fast the particle 'settles', or sediments. It is often used to reflect the rate at which a molecule travels to the bottom of a test tube under the centrifugal force of a centrifuge. The svedberg is technically a measure of time, and is defined as exactly 10 seconds (100 fs).
