Looking for an Ultra-low temperature freezer? Read this first! 
 
Summary - Deep ultra-low temperature (ULT) freezers are used to keep stuff 
under extremely low temperatures. This article talks about when to use this 
freezer and how to choose the best one. 
 
Labs have varied needs. It creates their requirements for different kinds of lab 
freezers. Depending on the kind of supplies and samples that the lab intends to 
store, one can go ahead and purchase a freezer that meets their requirements. 
Ultra-low temperature freezers are a mainstay in most of the biological labs. The 
freezer can keep the samples safe at -80 degrees centigrade. It also maximizes 
the storage space as per the lab footprint. 
 
Purchasing an ultra-low temperature freezer can be difficult. With a lifespan of 
almost 15 years, it is important to do thorough research and understand when 
and how should you specify a deep freezer for your lab. So take your time to 
make a purchase but before that let us first understand what a ULT freezer is. 
 
 
What is an ultra-low freezer? 
The ultra-low freezers are used to keep samples at a low temperature. These 
find a lot of use in the science labs. The pharmacy and lab freezers control 
temperature ranges of -10 to -25 degree centigrade. The low-temperature 
freezers function to almost -40 degree centigrade. 
 
The ultra-low freezers control temperatures further lower to even -85 degrees 
centigrade. All these freezers are equipped with temperature control. 
 
 
 
Ultra- low freezers applications   
The ultra-low freezers find a lot of use in biotech and biological storage 
applications. These are used in laboratories, blood banks, medical centers, 
research institutes, and recently to store the Covid-19 vaccine. The labs that are 
into performance testing use the ultra -freezers to understand their ability to 
perform at very low temperatures. 
 
The deep freezers find a lot of applications and if you wish to get one for your 
lab, then here is how you can pick the right deep freezer 
 
Picking a deep freezer for your lab 
The ULT freezers find use in the lab environment as these are used to ensure 
safe sample storage. These operate in the -50 to -80 degree centigrade 
temperature range. It lets researchers store many biospecimen samples, drugs, 
and enzymes. 
 
The lab professionals usually look at reliability, energy usage, storage, and noise 
when they select a deep freezer. It lets them see how it will impact their workflow 
and their operational cost. There are quite a few factors that need to be 
considered before you select the right ULT freezer. To be able to evaluate the 
options, here are the points that you should consider. 
 
Security 
You will be storing some precious samples in the deep freezer. The freezer must 
come equipped with an electronic lock system and a temperature monitoring 
system built into it so that you know that your sample is safe. 
  
Temperature control 
The lower you set the temperature of the freezer, the more will be the 
consumption of energy. It is thus vital that you match the storage and the 
temperature capacity to be environmentally-friendly 
  
Record keeping 
The deep freezer must offer accurate record-keeping. It is especially when you 
are storing valuables or samples that are sensitive to temperature. 
  
Specimen isolation 
Select a freezer that comes with separate compartments in the interior with 
insulated doors. This will not let the air access the compartment. The 
compartments can also be fitted to hold individual specimens with cell dividers. If 
you can label the compartments and the racks, then this will make sample return 
and removal easy and this enhances your efficiency. 
 
Sustainable freezers 
A sustainable deep freezer can save the planet as well as cut on your energy 
bills.  
 
Sound reduction 
The modern deep freezers are equipped with a sound reduction system. The 
front vent with fluid and the rear balcony vent lets the noise level stay at a 
minimum. 
 
Personalized solutions 
Before you order a deep freezer, make sure to check the variables like the 
number of compartments, right or left-handed door configuration, and voltage 
consumption. Some ULT freezers come with an inverter technology built into 
them, which lets the same freezer be used at varied volts. 
 
Ease of use 
Usability is another factor to consider when buying a deep freezer. Look at the 
inherent features and search for the interface that offers control and monitoring 
support. If the deep freezer offers remote monitoring, it can reduce the risk of any 
malfunctions. Else these may go undetected during a natural event like a storm. 
Also, check how ergonomic the freezer is to use it every day. 
 
Conclusion 
Deep freezers are a crucial part of the pharmaceutical, life science, and clinical 
labs where the scientists need to preserve the sample for long at a precise 
temperature. Take your time and do proper research before buying a ULT freezer 
for your laboratory. 
The deep freezer technology has advanced quite a bit in the last few years. The 
good news is that the ULT freezers available today have solved most of the 
problems that you may have encountered in your older model.
