  • Rapidly freeze non-medical samples with the new Thermo Scientific XBF40D -40°C Blast Freezer —a breakthrough sample preparation device for use prior to cold storage.
  • Your freezer is not a sample preparation device. Ultra-low and laboratory-grade freezers are designed to maintain samples at cold temperatures for long-term storage; they are not designed for and do not have the speed or refrigeration capacity to rapidly freeze plasma and other critical storage.
  • Using the new XBF40 for rapid cooling reduces the stress on your sample storage freezer, and freezes your samples quickly and efficiently.

Key Features:

  • Flexible Design: The XBF40D accommodates staggered loads and a variety of vessels such as carboys, bottles, racks with vials and more.
  • Accelerated air flow: A large, forced-air circulation freezes the product—fast!
  • Self-contained refrigeration system: Unlike previous generation blast freezers, the XBF is a plug and play requiring no customized installation and no remote compressors.
  • Trusted: All XBF40D freezers are manufactured with pride with high-quality materials and high-performance technology.


  • Durable, cold-rolled steel exterior.
  • Outer door, multi-point gaskets, maximizing temperature and security.
  • Polystyrene insulated inner doors featuring rare-earth magnets.
