Thermo Fisher Scientific CryoMed 7454 Undercounter Freezer

Cambridge Scientific ID: 24293 Category: Tag:


Modify six standard preset and 10 user-defined (20 steps each) freezing profiles for custom protocols to meet application needs with Thermo Scientific CryoMed Controlled-Rate Freezers: complete, one-piece freezing systems. Assembling and connecting electrical components has been eliminated with an integrated control panel and thermal printer. However, freezer functionality may be enhanced by adding a PC, installing MS Windows-based Controlled-Rate Freezing PC Interface software (included), and connecting an external inkjet printer.


Easy Programming and Monitoring:

  • Chamber and sample temperatures and operation status simultaneously display on backlit LCD.
  • Chamber temperature is monitored by fixed-mount Type T thermocouple.
  • Sample temperature is monitored by Type T thermocouple with flexible cable (included).
  • Pre-Cool step automatically begins temperature ramp when chamber and sample temperatures are equilibrated within 1°C.
  • Audible indicators alert operator when hold time has elapsed.
  • Operation continues if power outage lasts less than 10 seconds; audible/visual alarm sounds if outages last longer than 10 seconds.
  • Modifiable access code offers added security.

LN2 Freezing System Components:

  • Intuitive control panel and integrated thermal printer
  • Dual solenoid valves that increase LN2 injection volume for precise temperature control and accelerated freezing for optimum cell viability
  • Specially designed air handling system and liquid nitrogen ring that work in tandem for precise temperature control and uniformity
  • Overtemperature protection on heating element
