ASFRZRCK11

The ice-free FreezeBox™ is a new type of energy-saving environmentally friendly, safe, additive-free freezer box. The ice core aluminum alloy shell with high thermal conductivity of the alloy module ensures that the samples can be quickly cooled. The temperature difference between the sample holes is less than 0.1°C, which maintains a uniform temperature throughout the samples. Because the FreezeBox™ is ice-free, lightweight, and easy to carry it is ideal for collection of biological samples, or even to preserve unstable nucleic acid samples. Its compact design and ice-free technology allow for convenient use in a tissue culture incubator, bio-safety cabinet or any other application with limited space. The FreezeBox™ can be used with different ice cores, and a variety of thermal test tube modules allowing for usage with different samples and temperatures.

Features:

  • Low temperature protection for biological samples
  • Uniformity of temperature between the holes ensures consistency among samples
  • Different ice cores available for different storage temperatures
  • Applicable to a variety of thermal pipes and modules
  • Lightweight, compact, easy to carry when collecting biological samples
  • Easy to clean and disinfect
  • Highly durable and suitable for frequent and repeated use

Usage:
This product is easy to assemble and simple to use. After storing the ice core in the ultra-low temperature refrigerator for several hours place the desired tube module on the chilled core, and insert your sample or plate into the tube module. If you choose to use dry ice, take the core out, directly fill approximately 200g dry ice, then lay the tube modules on top of it.
