FreeZone Bulk Tray Dryers are designed for lyophilizing moderate to large bulk sample loads. They offer options for a built-in 6-port manifold and isolation valve.
The Bulk Tray Dryers feature a brushed stainless steel and glacier white, powder-coated steel exterior with blue accents, integral support stand with attachment port for connection to a FreeZone 6, 12, or 18 Liter Freeze Dryer (sold separately), and side-mounted power switch.
They include three 12.7” x 16.6” heated shelves and temperature probes for monitoring sample temperature. Chamber can accommodate two additional shelves (sold separately). A clear acrylic viewing door provides complete visibility of the shelves. A 200-watt electric heater on each shelf warms to +60° C and a microprocessor maintains the system temperature within 3° C of set point.
Lyo-Works™ OS provides a real time display of freeze dryer and tray dryer parameters on a 5" full color, capacitive touch screen on the connected FreeZone 6, 12, or 18 Liter Freeze Dryer (sold separately). Data may be exported via USB or Ethernet. A microprocessor-based controller allows up to 30 different temperature programs to be stored and repeated, each using up to 16 different steps. The display provides navigation to manual or program mode, probe temperatures, vacuum in mBar, Torr or Pa, step of the program in progress, time remaining in present step, and end of program, as well as alarms. Alerts and current operating parameter reading can be sent automatically to user-entered email addresses.
Optional 6-Port Tray Dryer Manifold accommodates either ½” or ¾” flask adapters and connect to flasks and other glassware. The optional built-in isolation valve separates the Bulk Tray Dryer from the freeze dryer to shorten time necessary to reestablish working vacuum levels and to provide a means for determining end point.
Samples must be pre-frozen. Freeze dryer, vacuum pump with displacement of at least 163 liters/minute, and freeze dry glassware (if not bulk freeze drying) are required (not included).
