Genevac’s miVac SpeedTrap can now be used for freeze drying or configured as a combined concentration/freeze drying workstation with a miVac vacuum concentrator.
Utilising the updated miVac SpeedTrap with continuous chill mode in conjunction with the miVac Super Vacuum pump, up to 250ml of water, or other solvents such as 1,4- dioxane may be freeze dried in a single operation.
Samples to be dried are simply placed in the rotor of the miVac concentrator and dried at full vacuum.
The vacuum boils the samples at below their freezing point - where they freeze and the ice sublimes away, leaving the sample as a dry powder.
To reduce drying times, a pre-concentration step, at a controlled vacuum, can be easily incorporated.
The miVac SpeedTrap and Super Vaccum pump may also be used as a stand-alone freeze drier.
Genevac has designed a range of accessories to allow the SpeedTrap to directly accept pre-frozen samples in either flasks or vials.
The freeze drying accessory jar is simply attached in place of the regular collection vessel. Flasks can be attached to the valves, or vials may be placed directly in the accessory jar, using the holders provided.
At 212 mm (8.3 inches) wide, the miVac SpeedTrap is a compact and cost effective solution for low volume freeze drying. As a combined system the miVac provides a versatile concentration and freeze drying tool for busy Life Science labs.
