Science. 1961 Jan 20;133(3447):193-4. doi: 10.1126/science.133.3447.193.

A simple procedure for concentrating aqueous solution by freezing is described. Solutions are frozen in test tubes, which are insulated on the sides and bottom, and allowed to thaw during centrifugation. Fractionation of solutes could also be achieved.

描述了一种通过冷冻浓缩水溶液的简单方法。将溶液在试管中冷冻，试管的侧面和底部进行隔热处理，然后在离心过程中解冻。溶质的分馏也可以实现。
