What to Consider When Buying a Low-Temp Freezer
Modern research labs depend on ultra low-temp freezers to keep biological samples and high-tech materials cold, at temperatures much lower than other commercial refrigeration units can manage. Manufacturers offer a stunning variety of options with a wealth of specialized features for almost any application, so choosing the right one for your facility can be overwhelming. Below are some factors to consider when deciding on a low-temp freezer.
Tips for Shopping for Low-Temp Freezers
Reliability
The contents of a freezer can represent years of work and millions of dollars in research, all of which can be wiped out by an equipment failure. Read reviews of each company you’re considering to narrow down your options and ensure you get the most reliable equipment available. As a general rule, choose a trusted manufacturer, and avoid untested technology from startups promising innovative designs.
Temperature Recovery Rates
Frequently opening the freezer doors can cause dramatic temperature fluctuations, which can damage or destroy sensitive samples. The temperature mapping data for each freezer should tell you how long the machine takes to recover. The faster the recovery rate, the less time your materials will be subjected to elevated temperatures.
Uniform Temperature
Any freezer can have warm spots and colder areas, which may be inconvenient or disastrous, depending on the application. If the materials you’re storing have to be kept at a specific temperature, look for a design that creates uniform temperatures throughout the freezer, without much variance between the top and bottom.
