Laboratory freezers come in distinct types broken down by temperature and configuration.


There are three common temperature categories of laboratory freezer including general purpose with pre-set temperatures between -20 and -30 degrees C, low-temp with pre-set temperatures between -30 and -45 degrees C, and ultra-low temp with pre-set temperatures between -45 and -86 degrees C. All pre-set temperatures are adjustable, but only within a narrow range, so it’s important to match freezers you’re considering with your temperature requirements. Jadwal MLS


Lab freezers come in two common configurations; upright and chest. Uprights can be further divided into free-standing and undercounter.

Upright Freezers

Upright freezers have the advantage of being easier to organize. Usually upright freezers have more shelves and you can relocate items in the freezer without having to remove other items that may be on top.

Larger uprights typically also have additional storage in the door which provides extra flexibility to store frequently used materials for quick access when needed.

Undercounter upright freezers are particularly good for storing smaller materials you need frequent access to because they can be placed out-of-the-way near the work station that uses them.

The disadvantage of upright freezers lies in temperature control. When you open an upright freezer, frigid air wants to spill down from the freezer. The drop in temperature can be dramatic making it more difficult to maintain a desired temperature. The more times you must open the door to conduct lab operations, the more pronounced the effect will be.

Something to consider when purchasing an upright lab freezer is inner compartment doors. Particularly for temperature sensitive materials, inner compartment doors allow you to control the temperature more precisely for those items protected by the doors. The temperature in the remainder of the compartment may fluctuate more with the opening and closing of the main door, while materials behind the inner compartment doors remains constant or closer to constant.

Another feature of some freezers is the ability to adjust temperature automatically and quickly each time the door is opened. This can make up for the lack of internal compartments and give you more flexibility in storage organization.
