Labconco FreeZone Stoppering Tray Dryers are designed for lyophilizing moderate to large loads and stoppering vials under vacuum. New Lyo-Works™ OS provides flexibility and convenience in an easy-to-use, touch screen display. Your samples are protected with remote notification and data recording. Features include hot gas defrost, side-mounted USB port and rear-mounted Ethernet connection. The console provides interior space for a vacuum pump (sold separately).
The upright stainless steel collector coil holds 6, 8, 12 liters of ice before defrosting. Choice of a -50° C (for aqueous samples) or -84° C (for low eutectic point samples including acetonitrile) collector cooled by an environmentally-friendly HCFC/CFC-free refrigeration system. Internal coil maximizes vapor-trapping efficiency. Optional PTFE-coated collectors withstand corrosive compounds.
Lyo-Works OS provides a real time display of collector temperature and vacuum level on a 5" full color touch screen. Flexible programming and control of optional drying accessories including End-Zone™ end point detection for flask freeze drying. One-touch data logging and display provides information to maximize sample quality and minimize run time. Customizable settings include language, time zone, temperature and vacuum. Alerts and feedback of current operating parameters can be sent automatically to user-entered email addresses.
FreeZone exclusive features protect your vacuum pump from costly damage. A vacuum break valve bleeds air into the system when power to the freeze dryer or vacuum pump is shut off for more than 5 minutes. A moisture sensor prevents refrigeration or vacuum start-up when moisture is detected in the drain line. Vacuum pump is automatically shut down when a leak is present in initial pull down or during run. Front viewing window makes monitoring vacuum pump oil hassle free.
The Stoppering Tray Dryers provide precise control and program flexibility for consistent performance. Three 16.5” x 12” temperature-controlled (±1° C), adjustable shelves with sample temperature sensors provide up to 594 sq. inches of shelf space. Circulating fluid in shelves ranges from -40 and +40° C and features an environmentally-friendly HCFC/CFC-free refrigeration system. Built-in pneumatic mechanism stoppers containers on all three shelves. The 1/8” OD backfill port introduces inert gas into the chamber, protecting samples from atmospheric moisture and contaminants.
Vacuum pump with a displacement of at least 163 liters/minute and freeze dry glassware (if not bulk freeze drying) are required (not included).
