설명

애플리케이션

Sodium polytungstate (SPT) is widely used to produce heavy liquid for sink /float analysis (gravity separation) and density gradient centrifugation due to its very high solubility in water.

기타 정보

A new medium for density-gradient centrifugation, the density can be adjusted to up to 3.1 g/ml
