Spin Freezer

Spin Freezer is useful for freezing & primary drying of samples in glass ampoules. By spinning ampoules, samples are frozen on the base unit without the need for pre-freezing. The centrifugal force holds the liquid sample in position and prevents frothing and bubbling during evaporation as the sample solidifies and sublimes. The spin freezer has an independent power supply and includes a timer to prevent spinner overrun after freezing. Removable rotor plates provided with system accept 5 different sized ampoules.
