FreeZone® Bulk Tray Dryers and Stoppering Tray Dryers have shelves to freeze dry samples in bulk or batch and connect to any FreeZone® 6, 12 or 18 Liter Freeze Dry System. A vacuum pump is required (not included).
Bulk Tray Dryer provides ample room to freeze dry bulk samples or samples in serum bottles or vials. It features a 200-watt heater on each shelf for heating to +60°C (140°F) and an Integral Support Stand that completes connection between Tray Dryer attachment port and Freeze Dry System. Other features include 210 square inches of total area in chamber that can accommodate two additional shelves and three sensor probes for monitoring sample or shelf temperature. Models with pre-installed 6-Port Manifold are available.
Stoppering Tray Dryer has a chamber with three shelves, each measuring 16.5" x 12", that hold serum bottles or vials. When the stoppering control is activated, the shelves raise via an expanding diaphragm that permits stoppering under vacuum of containers on all three shelves. With a 1 hp CFC-free refrigeration system and 1000-watt electric heater for cooling and heating fluid medium circulating through channels in the shelves from -40°C to +40°C. With microprocessor-controlled temperature programming and memory to store five programs and repetition of identical protocols. Includes three temperature probes, 3" diameter outlet for connection to FreeZone® System, control panel with operating switches and red LED alarm indicator.
