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.

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

Construction:

• Type 304 stainless steel
• Exterior powder-coat finish
• Foamed in-place polyurethane insulation
• Bulb-style gaskets for tight door seal; PTFE heat-breaks to prevent door from freezing closed
• Front- and top-access models designed for human IVF and easy “seeding”

Includes:

6′ (1.8 m) flexible stainless-steel transfer hose, 0.5 in. 35° flare, thermal paper, 25- to 9-pin serial interface cable/adapter, and 10′ (3 m) RS-232 cable
