Ultra low temperature freezers (ULT freezers) typically have a temperature range of -45C to -86C and are used for the storage of vaccine,drugs, enzymes, chemicals, viruses, bacteria, cell preparations, and tissue samples, among others. There are several designs for ultra low temperature freezers with varying sizes depending on how much storage is needed and available footprint space.

For frequent use, an upright ULT freezer allows easy access, individual adjustable interior compartments, and fast cooling after opening. A chest ULT freezer gives you safe long-term storage for lesser-used items. Table-top and under-bench ULT freezers are also available. With removable inventory racks, an ultra low temperature freezer can be used to store both freezer boxes and larger items. Look for good temperature control in fluctuating voltage conditions or extreme ambient temperature, and a range of temperature controls from simple manual settings to remote electronic monitoring with alarm systems.

Some types of materials require especially low temperatures. In these instances, you will likely need an ultra-low temperature freezer. These are designed to reach temperatures as low as -85° or -86°, making them an ideal appliance for any facility that requires a consistent temperature to properly store sensitive materials. Ultra low temperature freezers are typically great for consistency and power, but they may also use a lot of energy to maintain those extra low temperatures. This is important to note, as it is possible that you will see a little extra cost when it comes to your energy bill.


Upright ULT freezers

Upright freezers are one of the most common types you will come across. They come in a variety of sizes. You can find small ones that fit easily on a counter, an ideal solution for offices with limited space or only needing to store a small quantity of samples or medications. From there the sizes available will gradually grow larger, with the biggest capacities designed to satisfy the storage requirements of research facilities or hospitals.

Upright freezers often include some shelving to allow users to take optimal advantage of the space available. The upright design is useful for minimizing the space the freezers take up, particularly for the larger models that don’t take up much floor space for the amount of storage capacity they offer.

Chest ULT freezers

Chest freezers look a lot like other chest freezers. They tend to be large and they open from the top rather than the front. They offer quite a bit of storage space, but without the shelving upright medical freezers have that allow for orderly organization. Chest freezers are especially useful in cases where you need to be able to fit large items within the device. Unlike a deep freezer you’ll see in homes, they often come with some of the same special features found in other types of medical freezers, such as alarm systems to alert users if the temperature changes, digital temperature displays or a lock on the door.
