Upright stainless steel collector coil capable of removing 2L of water in 24 hours and holding 2.5 L of ice before defrosting
1/3 hp HCFC/CFC-free refrigeration system to cool collector to -50° C (-58° F). For aqueous samples. Not for use with samples containing acetonitrile, methanol or ethanol
LCD displays system operating parameters, set-up parameters and alarm messages. User configured to display vacuum in mBar, Torr or Pa and temperature in ° C or ° F. Also displays total hours of refrigeration system operation, time since refrigeration system was serviced, total number of hours of vacuum pump operation and time since the vacuum pump was serviced (in hours)
LED vacuum and temperature “waves” for display of relative system vacuum and collector temperature
Automatic start-up switch for collector cool-down and vacuum pull-down with manual override switches
Alarm flashes and beeps to indicate an abnormal system event has occurred, including: power failure, improper line voltage supply, collector temperature above -40° C, service vacuum pump (after 1000 hours of vacuum use) and moisture in collector. Pressing the Menu Switch displays the alarm message on the LCD
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
