4 questions to consider before buying a lyophilizer - Labconco

Jul 01, 2020 In order to effectively trap the vapor coming off your samples, you need a temperature differential of 15-20⁰ between the sample’s freezing point and the collector coil of your freeze dryer. If the collector is not cold enough the vapor will bypass the coil and enter the vacuum pump, potentially causing damage. It is also important to ...
