Thermo Scientific™ CryoMed™ Controlled-Rate Freezers
Customize protocols to meet application needs in this controlled-rate freezer, with six preset and 10 user-defined freezing profiles from which to begin.
Supplier: Thermo Scientific™ 7454
Description
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.
