Laboratory freezers in stock now

Click here to see the laboratory freezers in stock now at American Instrument Exchange.

We always have a lot of equipment in stock in our warehouse just north of Boston, including a variety of laboratory freezers. 

We have general purpose freezers with both automatic and manual defrost. We have undercounter freezers and giant double-door 50 cubic foot capacity freezers. We have ultralow freezers, cryogenic storage freezers, freezers designed for biomedical use, chest freezers, and more.

Below is a short list of some of the units we currently have in stock.

General purpose lab freezers

General purpose lab freezers are designed to store samples at consistent temperatures around -20°C. Some of these units have auto defrost features to prevent frost buildup; these defrost cycles can result in temperature swings of 4°C. For tighter temperature control manual defrost units might be an option but the tradeoff is a potential buildup of frost that has to be scraped off periodically. Examples include the VWR Symphony SCMPF models and Thermo Revco UGL series.

-30°C laboratory freezers

Lab freezers with temperature ranges down to -30°C or -35°C are designed for more critical storage applications than standard general purpose models, with high-performance lab and clinical grade refrigeration systems. These units are often used for storage of blood and blood components as well as enzymes, culture media, reagents, specimens and vaccines. Examples include Panasonic MDF series units, the Thermo ULT2330 and 3030, and Follett lab freezers.

Flammable material and explosion proof freezers

Safe cold storage of volatile or otherwise hazardous materials need specialized freezers: spark-free internal cabinetry is required, and in some cases top-mounted hydraulic explosion-proof thermostats and non-sparking compressors. These units are also manual defrost. Check out this Fisher Isotemp explosion proof model as well as these Fisher Isotemp flammable material options. We also have some nice LabRepCo flammable material storage freezers available.

Ultralow freezers

Ultralow freezers can be set to and run at temperatures of about -55°C to -86°C and are designed to preserve biological samples, drugs, enzymes, chemical, viruses, cell preparations, or tissue samples in an extremely cold temperature stable environment. Many labs opt for space-saving upright design ultralow freezers while other labs prefer larger footprint but generally more energy efficient chest freezers. For a long time the Themo Revco ULT2586 was the industry standard, but in recent years we’ve seen Thermo Forma ULT models become more popular as well as Thermo UxF units and Thermo TSX units. Some customers are brand-loyal to Nuaire and Sanyo models too, although we’ve only begun to sell these recently and don’t have a strong opinion of them one way or another.

So if you’re looking for a laboratory freezer please check out the selection at American Instrument. We’re happy to provide advice or guidance to help you select the unit that will work best for your lab. Thanks!
