miVac Lyo

The new miVac SpeedTrap™ has a continuous chill mode, which can be used to freeze dry up to 250ml of water, or other suitable solvent, such as, 1,4-dioxane. Samples to be dried may be placed in a suitable rotor in the miVac concentrator and dried at full vacuum using the miVac Super Vacuum pump. The low vacuum level boils the samples at below their freezing point, therefore the samples freeze and the ice sublimes away, leaving the sample as a dry powder. To freeze dry water and acetonitrile mixtures (from HPLC fractions, for example) then the LyoSpeed™ method should be used with the EZ-2 Elite or HT series evaporators.

The miVac SpeedTrap may be used as a stand alone freeze drier when connected to a Super Vacuum pump. miVac Lyo is a range of accessories that have been designed to allow the SpeedTrap to directly accept pre-frozen samples in either flasks or vials. Simply attach the freeze drying accessory jar in place of the regular SpeedTrap collection vessel and attach the freeze drying valves. Flasks can be attached to the valves, or vials may be placed directly in the accessory jar, using the holders provided. miVac combi system
The vacuum valve can be used to seal off the SpeedTrap from the concentrator, should you wish to configure your system as a freeze drier and a concentrator. In such situations, we recommend using the miVac pressure controller to allow selection of optimal vacuum levels for each process.
The miVac film shows all the possible configurations.
