FreeZone Triad Freeze Dry System is an all inclusive benchtop lyophilizer and stoppering tray dryer.
The processing shelf holds up to 441 3-milliliter serum bottles and four valves hold samples in flasks, serum bottles or ampules. Dual 1/3 hp refrigeration systems cool to -85° C (-121° F) for processing samples with low eutectic points. Upright stainless steel collector coil removes 1.84 liters of water in 24 hours and holds 2.5 liters of ice before defrosting is necessary. Fluid temperature may be set from -55° C to +50° C (-67° to +122° F) or to pre-freeze shelf temperature of -75° C (-103° F). The microprocessor controls circulating fluid temperature to ±1° C of set point. Features brushed stainless steel and glacier white epoxy coated steel exterior with a large acrylic door that enables you to view samples without interrupting freeze dry cycle and includes 12.4" w x 14.5" d (31.5 cm x 36.8 cm) processing shelf. Spacing between the shelf and top of the chamber accommodates containers with stoppers up to a maximum height of 148 mm and minimum height of 31 mm.
The Triad includes a pneumatic stoppering mechanism that inflates the diaphragm and lowers the stoppering platen above the shelf. No compressed gas is required.
One sample probe monitors sample temperature. Also included are four left-side mounted neoprene valve ports.
Microprocessor-contr
olled temperature programming from -55° C to +50° C (-67° to +122° F) during ramping and holding and -75° C (-103° F) during pre-freezing; and memory to store five programs, each with a pre-freeze segment plus five additional segments, for repetition of identical protocols. Red LED Alarm indicator that flashes and beeper sounds to indicate that an abnormal system event has occurred, including: shelf temperature variation more than ±2° C as measured by the shelf temperature sensor, collector temperature above -40° C, vacuum pressure changes more than 0.500 mBar, shelf temperature outside of set point during ramping, power failure, unevenly loaded shelf during stoppering, and service vacuum pump (after 1000 hours of vacuum use). Alarm messages are displayed on the LCD. The alarm mutes after one minute.
The vacuum control valve maintains set point vacuum level and the vacuum break valve bleeds air into the system when power to the freeze dryer or vacuum pump is shut off. If a power outage less than approximately 5 minutes occurs, the freeze dryer will restart and the refrigeration and vacuum system will resume operation once power is restored. If the power failure is more than approximately 5 minutes and the collector warms above safe limits, the freeze dryer will not automatically restart.
