Introduction to freeze drying - Labconco

Feb 25, 2020 To successfully freeze dry a sample, your equipment will need to meet certain requirements. First, the collector coil of your freeze dryer will need to be 15-20 degrees colder than the freezing point of your sample in order to trap the water vapor that is being released. You will also need a vacuum pump that can reach a minimum of .020 mBar.
