Best Laboratory Refrigerators : Top 8 Pick For 2022 with Buyer’s Guide

Since there are a variety of refrigerators to choose from, the odds are good that you'll choose a one-size-fits-all refrigerator meant for domestic use. Although they're great for keeping beverages and perishable food cold, they aren't meant to be used in the lab.

Domestic refrigerators, even those from the best brands, fluctuate in temperature and usually have a range of 0 to 10 degrees Celsius. However, such a system is not sufficient to store medications and vaccines. Therefore, the most important aspect of a laboratory refrigerator is that its temperature system remains constant rather than fluctuates frequently.

If you're in charge of a laboratory or a medical store, you know how important it is to keep all your valuable items in pristine condition. But, unfortunately, even a tiny mistake in the temperature system can cost you thousands of dollars. For this reason, it is inevitably necessary for you to have the best laboratory refrigerators available.

Don't get worried; we have compiled a few refrigerators for you, examining their features and functions. So sit back there and enjoy the article.

How to Choose the Right Refrigerator

In the midst of financial constraints, researchers often decide to purchase domestic refrigerators and freezers to save money, but before choosing such a product, consider these factors:

Accurate Temperature Monitoring

Especially for storing biological items, the temperature should be monitored very carefully. And this is one of the primary features of the best laboratory refrigerator. Sometimes, unfortunately, the clinics and laboratory authorities compromise this by purchasing low-quality freezers just to save a few bucks that might cost them thousands of dollars instead.

In the CDC's definition, vaccines and medical items need to be treated immediately if the temperature exceeds the manufacturer's recommendation. It is possible for materials and substances to be harmed if the authority fails to keep them properly. Because of this, it is important that we, as the authority, search for devices that provide intelligent temperature monitoring.

Extensive Alarm System

Nearly every top brand offers a comprehensive alarm module for laboratory refrigerators nowadays. In addition to the temperature fluctuations, you can see their records later to evaluate.

Sensor alarm, power alarm, and normal temperature fluctuation alarms are all included in an intelligent alarm system. This is why we strongly recommend choosing a freezer that is equipped with these kinds of features.


Oh, yeah. This is a somewhat general view of how a freezer should appear. It's not just for laboratory freezers. It could be any device that requires some space. From its own perspective, both interior and exterior sizes are equally important. The freezer should fit well in the space designated for it. It also needs some space around it since it leaves some heat.

Furthermore, be sure that the unit you choose has the right capacity as well. Although this is crucial, we often ignore it. The reason for this is that if you expect to buy a large refrigerator and you don't have many items to store inside, it will have more temperature fluctuations. In other words, the fuller the freezer, the more stable the temperature is.

You should therefore decide on the size of your laboratory refrigerator according to how much you're going to store there.

Safety and Security

When you're doing your best to manage a high-profile refrigerator to keep your medications and vaccines well, what happens when the power goes out, and someone opens the freezer and leaves it ajar? Lab freezers, in particular, should be equipped with a good security system as well as temperature regulation.

Look for features such as self-locking, auto-closing, etc. In case you frequently open your freezer, pick an appliance that offers a rapid cool-down setting to return the freezer to its ideal temperature in a timely manner. Details read here.

An additional heavy-duty fan: In order to deal with hot conditions, many medical refrigerators are equipped with additional fans or at least an additional heavy-duty fan. Even if a lab has air conditioning, it can still be a hot place to work due to the number of people and equipment involved.

More sturdy: door construction- the doors of a medical refrigerator will most likely be opened and closed frequently during normal operation. As a result, the door seals and hinges need to be more sturdy as they are designed to endure heavy use.

Low noise: Garages, factories, and laboratories tend to be loud with the combination of people talking and mechanical noise. Medical refrigerators tend to be quieter, so the sound level can be kept low.

Visual and audible alarms: Due to the increased noise level, alarms that are both visible and audible are necessary to inform users when they leave a door ajar.

Frequently Asked Questions

1. What can I store in a laboratory refrigerator?

Well, this is one of the fundamental questions that one should ask before a lab refrigerator purchase. According to the capacity, functions, and temperature- the answer varies. A certain type of refrigerator or freezer is designed to house a certain type of material.

If you, for instance, want to store samples and reagents, make sure the unit suits your need. However, generally, when you're purchasing a medical lab refrigerator, you're likely to stock any medication, vaccine, drugs, purpose equipment, etc. And nearly every refrigerator above suits these requirements.

2. What's the difference between a lab and a household refrigerator?

There are so many additional options in a lab fridge. Even you can add new features to it as you like. On the other hand, with a household or domestic freezer, you get what you buy. In other words, they are only designed to keep your food cold; you don't have any other choice there.

For example, in a laboratory refrigerator, we get automatic dialers, an extensive alarm module, adjustable shelves, and much more.

When it comes to longevity, it is important to take the product's strength into consideration. Stainless steel and other high-quality materials make lab freezers more likely to withstand tough conditions. Since domestic refrigerators are not designed to withstand the humidity and chemicals present in laboratories, they can significantly reduce their lifespan if used in this setting.

Therefore, it may be tempting to choose domestic refrigerators due to the low price, but in the end, it doesn't lead to savings.

3. Can I store hazardous chemical substances and flammable liquids?

Of course, you can because the good thing about lab refrigerators is that they are explosion-proof. Furthermore, it is safe for combustible materials to be stored here since it lacks electrical equipment, which prevents sparks from causing a fire.

Aluminum and stainless steel are common materials found in laboratory refrigerators for adjustable shelves. Coated wire shelves are also available. By design, most refrigerator shelves are safe and easy to use.

4. Which refrigerator is more energy efficient?

As opposed to private homes, laboratories, pharmacies, and hospitals frequently house more than one refrigerator in a room. It is possible that there could be hundreds of refrigerators throughout the entire site. It is for this reason that power consumption for fridges in a laboratory environment is so important. The energy efficiency of domestic refrigerators is already rated, but medical refrigerators are even more efficient.
