Four Aspects of Medical Freezers

From extremely low temperatures to unique locking mechanisms, medical freezers offer many different features that a normal fridge cannot. Medical freezers can maintain extremely constant temperatures and can be installed with alarms to keep your most vital medicine and lab specimen safe. So how, exactly, do medical freezers differ from normal home coolers?

Temperature
The major difference between regular and normal freezers is a variance in temperature abilities. For vaccines and tissue storage, a medical freezer must be much cooler to maintain a constant and sterile environment. Depending on needs and location, a freezer can be a variety of different temperatures, including:

  • Home: For the home, a freezer should stay around -17 degrees Celsius. This temperature can fluctuate greatly without harm to freezer contents.
  • Restaurant: While most restaurant freezers stay around the temperature of a home freezer, some specialty foods require temperatures that plummet to -30 degrees Celsius. These temperatures may also change slightly without harm.
  • Medical: These freezers must remain much cooler for vaccine and specimen storage. You can purchase vaccine freezers that maintain temperatures down to anywhere from -30 to -86 degrees Celsius (the lowest medical freezer storage capacity for labs.) Interestingly, some cool storage can dip down to an amazing -209 degrees Celsius in cryobanks.

The most important temperature feature of these freezers is the fact that they can maintain extremely precise temperatures that don’t fluctuate like most appliances do. In the medical field, it’s important to keep a steady temperature and humidity, a main component of most medical freezers.

Locking Mechanisms
Locking mechanisms and alarms are another specialized aspect of medical freezers that differ from normal commercial coolers. Often, expensive and vital specimens, evidence, and medicine are stored in medical grade freezers. Because of this, locks and alarms can be easily installed in most of these appliances. If security is especially important to you, it’s a good idea to inspect a model of the freezer before purchasing. If you can’t clearly see the locking mechanism, ask a sales representative about the engineering that goes into keeping your cold items secure.

Installation versus Portability
There is a wide variety of models and installation types of medical freezers that tailor make them for a number of different situations. Chest coolers are common for bulk storage. If you know that you’ll be in and out of your freezer often (such as in a lab), consider purchasing an upright freezer. Multiple compartments will make sure that temperature is isolated and kept constant. Portable freezers are a good idea for tissue transport. Be aware that these smaller models can’t maintain as even of temperature.
Choosing a Medical Freezer
Often, medical freezers tout many different features that normal freezers do not. These aspects can include extremely low temperatures, mechanical locks, alarms and even portability and installation options. When choosing your medical freezer, you may also want to inspect the model before purchasing to make sure that all of your special features are up to par

Mini Freezers

Mini freezers come in a variety of different types. When considering a mini freezer purchase it is important to consider the particular storage needs you are attempting to address before selecting a particular type of mini freezer unit.
There are five basic types of mini freezer available for shoppers to select from. These are small upright freezers, small chest freezers, medical freezers, blood freezers, 12 volt portable freezers and mini commercial freezers.
Mini Upright Freezers
There are many different models of upright freezers that can be purchased in miniature sizes.   Small freezers like these are ideal for situations where a front opening freezer appliance is required, but only a minimal capacity is needed. These are simply scaled down versions of full sized stand-alone upright freezer models – they are often used as bar fridge freezers.
Mini Chest Freezers
Also available in stores are lots of small chest freezer options. These devices are handy when energy efficiency is required in a freezer – they are more efficient than upright units. Appliances of this type are very handy for constrained spaces where there is not room to open a front mounted door. Being able to access the freezers contents from above reduces the floor space required for installation a chest freezer.
Mini Medical Freezers
Small medical freezers are appliances specifically designed for freezing products in medical and laboratory settings. A medical freezer is usually a very well insulated appliance designed to keep the contents in very deep freezer. Many models are capable of freezing to -20, -30 or -35 degrees Celsius, an important requirement in scientific applications.
Mini 12 Volt Portable Freezers
12 Volt freezers are used for a variety of diverse applications. They are very popular for use on fishing and camping trips as they provide easy to use off-grid frozen produce. Some buyers even purchase 12v car refrigerator freezer units for their vehicles – both for in town use and major off-road expeditions.
Mini Commercial Freezers
Many retail establishments require small glass door display freezers for their premises. Mini display freezers are frequently found in gas stations and convenience stores where they are used for the display of spontaneously purchased items like ice-cream and the like. Small commercial freezers also are often frequently seen in the checkout lanes of supermarkets.
As I have discussed, there are many different types of mini freezers available. Whatever your needs for frozen items, one of these different small freezer categories will certainly be appropriate for your particular application.
