Lyophilizer, FreeZone 12 L Console Freeze Dry System
FreeZone 12 Liter Cascade Console Freeze Dry System is designed for light to moderate loads of low eutectic point samples. Removes a maximum of 8 liters of water in 24 hours. The stated capacity rating represents the maximum achievable and is based on freeze-drying plain water under ideal conditions. Individual results will vary depending on application and, in most cases, be less than the stated maximum. FreeZone Freeze Dry Systems have collector temperatures that reach -58 °F / -50 °C, ideal for use with samples in aqueous solutions. Except for FreeZone 4.5 Liter models, these freeze dryers require a drying chamber or tray dryer for operation (not included). All models also require a vacuum pump for operation. NOTE: These freeze dryers are not recommended for use with samples containing acetonitrile, methanol, or ethanol. If your samples contain acetonitrile, methanol, or ethanol, please see FreeZone Freeze Dry Systems with cascade refrigeration that reaches lower temperatures.
Product Dimensions: W 32" × D 28" × H 36"
- 1 1/2 hp HCFC / CFC-free refrigeration system to cool collector to -58 °F / -50 °C
- Brushed stainless steel and glacier white, epoxy-coated steel exterior with blue accents
- Upright stainless steel collector coil and chamber
- LCD that displays system operating parameters, set-up parameters and alarm messages
- Red alarm light that flashes and beeper that sounds to indicate that an abnormal system event has occurred, including: power failure, improper line voltage supply, collector temperature rise above -40 °C, service vacuum pump (after 1000 hours of vacuum use), and moisture in collector
- Moisture sensor that prevents refrigeration or vacuum start-up when moisture is detected in the collector chamber area
- Vacuum break valve that bleeds air into the system when power to the freeze dryer or vacuum pump is shut off.
- LED vacuum and temperature "waves" for at-a-glance display of relative system vacuum and collector temperature
- Vacuum control valve that maintains setpoint vacuum level
- Rear-mounted RS-232 port to transmit data to a user-supplied computer. Transmission intervals may be user-configured for 10, 30, 60, 300, or 600 seconds
- Automatic start-up switch for collector cool-down and vacuum pull-down with manual override switches
- Retractable, 9" collector drain hose
- Power switch and rear-mounted electrical receptacle (for vacuum pump connection)
- 3/4" OD vacuum connection, three feet of 3/4" ID vacuum hose and two clamps
