Bio Freezer

Control rate Cryogenic Freezers
Spectra Cryogenic Freezers are capable of achieving temperatures of -300 F. To be able to withstand this extream temprature difference, Spectra has incorporated special construction techniques in addition to welded structural steel framing and heavy duty welded stainless steel liners.

Cooling Rate


Controlled rate freezing before long term storage maximizes viability for a wide variety of cell. Programmed, uniform cooling rates are effective for a variety if freezing application. A major reason to use controlled rate freezing equipments is that the temprature compensation provided during controlled rate preservation for release of the latent heat result in improved post cryopreservation cell viability.

  • Mainfold located in fan plenum, LN2 is not sprayed directly on parts.

  • Low pressure supply (20psi) is controlled by cryogenic solenoid.

  • Low pressure supply provides most efficient use of liquid nitrogen.

  • Customer supplied liquid nitrogen vaporized through stainless steel spray manifold and nozzles.

  • Redundant safety solenoid valve.

  • Air circulation by properller type fans with externally mounted motors.

  • Low temperature fall safe limit.
