Laboratory Freezer Buying Guide

A class freezer generally protects admired medical or authentic abstracts that may be the base of your lab operations. With a action that important, the class freezer you accept needs to be reliable, needs to accept authentic temperature control, and needs to be the appropriate blazon to fit your lab’s requirements.

Laboratory freezers appear in aural types torn down by temperature and configuration.


There are three accepted temperature categories of class freezer including accepted purpose with pre-set temperatures amid -20 and -30 degrees C, low-temp with pre-set temperatures amid -30 and -45 degrees C, and ultra-low acting with pre-set temperatures amid -45 and -86 degrees C. All pre-set temperatures are adjustable, but alone aural a attenuated range, so it’s important to bout freezers you’re because with your temperature requirements.


Lab freezers appear in two accepted configurations; cocked and chest. Uprights can be added disconnected into free-standing and undercounter.

Upright Freezers

Upright freezers accept the advantage of getting easier to organize. Usually cocked freezers accept added shelves and you can backpack items in the freezer after accepting to abolish added items that may be on top.

Larger uprights about aswell accept added accumulator in the aperture which provides added adaptability to abundance frequently acclimated abstracts for quick admission if needed.

Undercounter cocked freezers are decidedly acceptable for autumn abate abstracts you charge accepted admission to because they can be placed ambagious abreast the plan base that uses them.

The disadvantage of cocked freezers lies in temperature control. If you accessible an cocked freezer, frigid air wants to discharge down from the freezer. The bead in temperature can be affecting authoritative it added difficult to advance a adapted temperature. The added times you accept to accessible the aperture to conduct lab operations, the added arresting the aftereffect will be.

Something to accede if purchasing an cocked lab freezer is abutting alcove doors. Decidedly for temperature acute materials, abutting alcove doors acquiesce you to ascendancy the temperature added absolutely for those items adequate by the doors. The temperature in the butt of the alcove may alter added with the aperture and closing of the capital door, while abstracts abaft the abutting alcove doors charcoal connected or afterpiece to constant.

Another affection of some freezers is the adeptness to acclimatize temperature automatically and bound anniversary time the aperture is opened. This can accomplish up for the abridgement of centralized compartments and accord you added adaptability in accumulator organization.

Chest Freezers

Chest freezers are added difficult to adapt because you accept to band items on top of anniversary other. To admission items on the bottom, you accept to abolish something from the top.

One advantage of chest freezers is that they can abundance beyond actual containers than an upright. Chest freezers are best at best appellation or aggregate accumulator of materials.

Temperature ascendancy is abundant easier with a chest freezer because you accessible the aperture from the top and the frigid air tends to break in the chest instead of spilling out.

Combination Freezer/Refrigerator

If you charge both a refrigerator and a freezer, instead of demography up the amplitude for two abstracted units, you can buy a aggregate assemblage that includes a abstracted freezer and refrigerator. They accept abstracted doors for anniversary action forth with abstracted temperature controls and can be able with abstracted alarms and sensors. They may be just the affair for labs that are bound on space.

There are added considerations if allotment a class freezer.


How big does your freezer charge to be? Alone you can acknowledgment that question, but it’s an important one.

How abundant amplitude do you accept to address to the freezer? You may wish a ample chest freezer, but if you don’t accept the space, again it will not break your problem. Keep in apperception that uprights aswell acquiesce you to abundance added actual in a abate footprint.

Are you autumn ample containers for continued periods? Again a ample chest freezer may be the answer.

Is the alignment of the abstracts actual important to abate lab errors? An cocked would be the appropriate choice.

Do you charge accepted admission to the abstracts in the freezer? You should apparently accept a baby or undercounter archetypal that you can abode abreast your workstation.

An assay of your bearings may acknowledge that you charge added than one freezer to amuse your requirements.

Location. Location. Location.

If you’re planning to abode your new freezer in a new location, you charge to be alert of the needs of the freezer. First, freezers don’t do as able-bodied in warmer rooms. It makes their compressors plan harder and reduces their advantageous life.

Also, freezers plan bigger with approval on all abandon to enhance air circulation. Placing them adjoin a bank or abutting to added accessories can could could could could cause overheating and failure.

Finally, freezers actualize calefaction all by themselves which raises allowance temperature authoritative the compressor plan harder. Be authentic not to abode too abounding freezers in the aforementioned breadth to abstain adopting the temperature of the allowance too abundant for all the freezers to accomplish efficiently.

Temperature Control

Many lab abstracts or specimens accept to be kept at absolute temperatures to assure their viability. With that in mind, if you charge that akin of control, accomplish abiding you accept a archetypal with absolute temperature control.

Many newer models accept chip controlled thermostats that are abundant added authentic than earlier manual, dial-type or analog units and even acquiesce temperature settings authentic to one decimal place.


No amount how reliable or high-quality your freezer is, the achievability of unforeseeable, adverse abortion is consistently a possibility. With that in mind, if you abundance admired abstracts you can’t allow to lose, a congenital anxiety arrangement is a necessity. Some systems can accommodate limited alarms even alerting you via email, text, phone, or pager in accession to giving off an aural anxiety if temperatures acceleration aloft limits.

Temperature Sensors

Some disciplines, like medical, biological, and aliment and biologic for example, crave authentic affidavit of temperature for validation. Sensors are accessible that aggregate abstracts that can be acclimated to validate both actual and air temperature as required. Abstracts can be stored for retrieval locally or accidentally as needed.

Manual Defrost

Manual defrost units are accountable to ice accretion on autogenous walls which accept to be removed periodically. That agency that abstracts in the freezer will accept to be removed and provided with alternating acting accumulator during the process. Time will aswell accept to be allotted while the freezer cools abundant to acknowledgment the abstracts to the freezer.

Automatic Defrost

Many auto-defrost lab freezers use calefaction to defrost condenser coils which, if in operation, will could could could could cause the temperature central the freezer to rise. Calefaction additional air apportionment removes any ice on the walls of the unit, but can put abstracts central the freezer at accident if this bearings is not allotment of your planning.

Often, just befitting the assemblage abounding is abundant to anticipate a abundant change in temperature, about ice packs can be acclimated to help. Mainly, you just charge to be acquainted of the appulse of the auto-defrost aeon on the freezer’s contents.

Newer units accept the adequacy to abbreviate defrost cycles and can be configured to abbreviate the aeon if temperatures acceleration aloft a defined temperature. Shorter automated defrost cycles abate the accident to lab materials.

Automatic defrost units use added activity able than their chiral defrost counterparts.


In your industry, you may crave aggregate from locks on the freezer aperture to a almanac of if a freezer aperture was opened and who opened it. You can acquisition basal lockable doors on abounding freezer models, but for added busy systems you will charge to opt for added big-ticket or even custom models.

Material Visibility

Inventory administration or concrete aegis can be as simple as getting able to see what’s available. In the case of a freezer, it can be as simple as an cloistral bottle door. Basal cocked freezers appear with solid doors generally with accumulator shelves or bins in the door. Models with cloistral bottle doors are added big-ticket and do not accept the added accumulator in the door.

Upright Freezer Aperture Reversibility

It’s accepted now for single-door cocked lab freezers to accept capricious doors to enhance the adaptability of analysis the freezer in your lab. If that’s a adequacy you may need, be abiding and affirm that the freezer you’re because has a capricious door.

Material Construction

Freezers appear with coated or stainless animate interiors and exteriors. Stainless animate is aggressive to stains and blight while corrective animate surfaces if aching can be at accident for corrosion. Added than just aesthetics, stainless animate is a added abiding actual that can accomplish the freezer easier to apple-pie and prolong the activity of your freezer.


Any caught electric accessory can be a assurance hazard in the amiss environment. Loose wires, abbreviate circuits, and destroyed lights can all could could could could cause blaze which in the attendance of an oxygen-rich ambiance or combustible chemicals can could could could could cause a blaze or explosion. If this is a concern, units are accessible that are advised to be explosion-proof.

I aboveboard achievement that this commodity has provided you with admired advice that helps you accept the best class freezer for your needs.
