Freeze Dryers

FreeZone Freeze Dryers are designed to handle the lyophilization needs of research and pilot plant laboratories. Benchtop and mobile console models are offered. Collectors that reach -50° C are available with capacities from 2.5 to 18 liters. Freeze Dryers with collector capacities that reach -84° C are ideal for freeze drying samples with low eutectic temperatures including ones containing acetonitrile. A 4.5 liter freeze dryer that reaches -105° C is available, which is suitable for samples containing dilute methanol and ethanol.

Gail was responsible for something irreplaceable: a key link to the future of her company... and a cure. 
When she visited Kelly at Labconco, Gail's struggle led to an epiphany that would change how laboratory freeze drying is done. With the creation of Lyo-Works OS, samples can now be monitored from anywhere. And with End-Zone™ End Point Detection, now FreeZone Freeze Dryers can even send you an alert when your samples are completely lyophilized.

Aseptic Adapter Usage and Overview

Valved flask adapter to maintain aseptic conditions when freeze drying. Used with Labconco Fast Freeze Flasks 120mls up to 2000mls and Mini Stoppering Chamber. These adapters allow the user to fill a freeze dry flask under sterile conditions prior to lyophilization. After filling the flask, the valve is closed off isolating the contents for transportation to the freeze dryer. Once the flask is attached to the freeze dryer and a vacuum is pulled, open the flask to vacuum using the adapters valve. After freeze drying, close the valve and transport the samples back to the biosafety cabinet to open.
