The FreeZone® bulk and stoppering tray dryers have a stainless steel interior and epoxy coated, stainless steel exterior. Units include three probes for monitoring sample and shelf temperature. Microprocessor controlled temperature programming from −40 to +40 °C during ramping and holding in stoppering tray dryers, whereas in bulk dryers a microprocessor maintains the system temperature within 3 °C of the set point (maximum 60 °C). Units have an LCD display and audible/visual alarm indication for temperature and vacuum changes.

• Compact design for moderate to large bulk loads or numerous sample batches
• Precision with 3 heated shelves up to +60 °C
• Flexibility: temperature and vacuum level controls in 30 programs with up to 16 segments each
• Quality reassurance with onboard data collection and real time graphing
• Sample probes with remote notification of operating parameters or alerts

Three 12,7×16" heated shelves with sensors for monitoring sample temperature provide 632 sq.

Lyo-Works™ OS provides flexible programming and control with a real time display of freeze dryer and tray dryer parameters on a 5" full color touch screen on the connected FreeZone 6, 12, or 18 liters freeze dryer (sold separately). 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.

Optional 6-Port tray dryer manifold accommodates either ¹/₂" or ³/₄" flask adapters for flask freeze drying. 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.
