In the life science laboratory, most expensive samples and substances
are accumulated in laboratory refrigerators/freezers.
Main specifications for selecting a laboratory freezer involve usage
or application, freezer kind, configuration, temperature variety,
temperature constancy, and power competence. A freezer temperature
variety of –20 to –40 °C gives secure and steady storage
situations for different kinds of cells and reagents. The value and
appropriateness of the lab freezer, though, are generally considered
when in certainty the laboratory may be employing an out-of-date or
even a broken unit.
There are many sizes and patterns of lab freezers obtainable, plus under-counter,
freestanding, double-thick, and chest freezer forms. A first
consideration in selecting a freezer form is the availability of
space accessible in the lab. Upright freezers take up a slighter
footprint, and it is simpler to place samples within, but chest
freezers keep cold air improved and recover faster when uncovered.

Freezers can also be arranged for general use or particular as for sample
freezers, enzyme freezers, vaccine freezers, blast-proof freezers,
and so on. Though a unique freezer might be a very striking
alternative, a general-use freezer coupled with conventional bottles
may be well adequate for your lab’s requirements.
Freezers work best in rooms that are not excessively warm—to standby the
compressor—and with as a minimum numerous inches of authorization
about all sides to let air circulate. Rooms involving freezers should
be well-aerated, again to let chilling of compressors. Ignore placing
too many freezers in single room.
