A freezer is a piece of must-have equipment for your laboratory. You need to select the right freezer, but that is not as easy as it seems to be. You might believe it or not; there are many aspects to consider to select the right freezer.
If you install the wrong freezer, it can damage the items you store in the unit, which will entail money wastage in replacing your item inventory.
The Necessity of a Laboratory Freezer
The necessity of a laboratory freezer stems from the fact that temperature-sensitive items need to be stored at the right temperature environment.
Items like vaccines, blood samples, specimens, etc., require stable temperature environments to retain their potency and minimize the risk of complications, such as bacterial growth or developing instability.
Such freezers provide the appropriate cold storage facility for laboratories for storing temperature-sensitive items in a controlled temperature environment.
To help you to invest in the right freezer for your laboratory, we outline here the key aspects you should look at before you purchase a freezer for your laboratory:
Firstly, assess what items you will store in your freezer, which will dictate the temperature range required for your prospective freezer. The standard temperature ranges for laboratory freezers are:
- General-purpose laboratory refrigerator ( 0 to 10 degrees C).
- Commercial freezer( -30 to 0 degrees C).
- Ultra-low temperature freezer (-86 to -40 degrees C ).
- Cryogenic freezers (up to -125 degrees C).
The items you will store in the freezer will have specific temperature requirements, so assess the temperature requirement before finalizing a purchase.
Figure out what volume of items you are going to store in the freezer. So, choose a freezer that can hold that capacity. It is a good idea to look at the outside dimensions of a freezer to determine whether it will fit into the location you have reserved for it in your laboratory. You can also purchase multiple smaller freezers to ensure that there will be less downtime if one of the units goes off. Usually, more extensive facilities, like research laboratories, institutes, hospitals, medical laboratories, require larger freezers.
Ventilation is one of the critical considerations for selecting a freezer for your laboratory. Keep in mind that ventilation in freezers varies from model to model. Usually, the larger the ventilation area within the freezer, the more energy-efficient it is. Check out if there is any blockage in the air inlet and outlet. If there are any ventilation regulations in your area, ask the provider to custom it accordingly.
Temperature Monitoring System
Check out if your prospective freezer has a temperature monitoring system, which is a must if you will store temperature-sensitive items, like vaccines. When you keep such items, you need to monitor the temperature to ensure it does not go out of range. And if it happens, the items will get damaged and become unfit for use.
You should go for a freezer with a temperature alarm to send an alarm if the freezer temperature goes out of range. Besides, it would be best to go for a freezer with a digital key lock on doors, temperature chart recorder, backup battery system to ensure the unit keeps working even during electricity outages. Most laboratory freezers come with digital temperature displays, enabling you to keep an eye on whether the temperature is within the prescribed range.
Broad Parameters for Choosing a Laboratory Freezer
Despite a laboratory freezer’s ability to keep items in cold temperature environments, there does not exist any universal freezer that is ideal for all laboratories. So, it would help if you chose a freezer that is:
It should maintain the necessary temperature and be safe. Ensure that there is no prospect of any hazards or sparks. Moreover, it should maintain a stable temperature, so test the freezer on these aspects before you purchase.
Laboratory freezers have to withstand heavy usage, so they need to be robust. So, go for a freezer that has a ducted air waft for quick temperature recovery, self-closing doors, and strong shelves. Ensure that it can withstand heavy usage in your laboratory.
High standards of security are a must for a laboratory freezer. Everybody in your laboratory should not get access to your freezer. Ensure that the freezer you choose has a lock to prevent any unauthorized access.
Bear in mind that the right freezer can make your business go round, but the wrong one can break it. Therefore, make sure that you invest in the right cold storage for your laboratory. And we believe that the steps outlined in this article will help you to spot the right freezer.
