-20 & -30 Lab Freezers

Manual defrost -20°C and automatic defrost -30°C laboratory freezers accommodate a variety of capacities, demanding, space challenged environments, and samples and applications ranging from routine to complex.

  • Environmentally-friendly, non CFC and HCFC refrigerants
  • Energy savings without sacrificing protection
  • Alarms built in, plus connectivity options for state-of-the-art monitoring and reporting
  • Quiet operation
  • Keyed security, including power switch and setpoint
  • Easy mobility plus lockable casters
  • Ergonical handles
  • GMP Clean Room Class A / ISO 6 (ISO EN 14644-1) compatible (TSX series only)


Automatic defrost freezers, when compared to manual defrost freezers, do not require you to remove samples prior to defrosting, saving you time to focus on what matters most: your work.

Automatic defrost freezers feature forced air circulation for uniform temperature throughout the cabinet, provide faster door opening recovery, and feature non-invasive temperature and time based defrost cycles.  

Sample types: Reagents, pharmaceuticals, biologicals, and other commonly used laboratory materials such as primers, siRNA molecules, and fetal bovine serum

  • V-drive technology provides improved temperature uniformity that continually adapts to the lab or clinical enviroment 
  • Whisper quiet operation 
  • GMP Clean Room Class A / ISO 6 (ISO EN 14644-1) compatible with appropriate pre-install preparation

Manual defrost freezers, or cold wall freezers, are most commonly used in BioTech and Pharma R&D applications, and are designed for applications in which even slight cabinet warming during auto defrost cannot be tolerated.

Manual defrost freezers contain refrigeration coils located inside the walls of the cabinet. The coils transfer refrigerant to the walls of the cabinet, whereas auto defrost freezers utilize forced air circulation and heat injection to prevent frost build-up.   

Sample types: Enzymes, pharmaceuticals, MMR vaccines, and other samples that require -20°C storage

  • V-drive technology provides improved temperature uniformity that continually adapts to the lab or clinical enviroment 
  • Whisper quiet operation 
  • GMP Clean Room Class A / ISO 6 (ISO EN 14644-1) compatible with appropriate pre-install preparation
