Freeze drying: Illustrated toolkit for general users
15 Sept 2019Freeze-drying is not a straightforward process and it requires a good balance of several factors. In this application note, BUCHI explores freeze-drying hardware, discusses the most important parameters and steps in sample preparation, outlines the freeze-drying process itself, and finally explains how to perform freeze drying when solvents other than water are used, either pure or diluted.

Evaporators and Freeze DryersCentrifugal evaporation is used for solvent removal from a sample. This is a useful technique for sample concentration or sample drying. Many centrifugal evaporators are modular with a central vacuum pump for generating low pressure. Useful features of evaporators or vacuum ovens include minimal solvent bumping, solvent resistance, computer control, temperature regulation and benchtop design.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Freeze Drying
