Ultra-Low Temperature (ULT) Freezers
Authorized-distributor pricing on ULT freezers from Haier Biomedical, Scientemp, and True Scientific, with Southern California freight coordination and nationwide shipping.
What Is a ULT Freezer?
An ultra-low temperature (ULT) freezer holds samples at -40°C to -86°C, well below the range of a standard laboratory or low-temperature freezer. Labs rely on ULT freezers for long-term biobanking, cell line preservation, vaccine and reagent storage, and any application where sample integrity depends on a stable, deep-cold environment.
Legacy Lab Supplies is an authorized distributor of ULT freezers from Haier Biomedical, Scientemp, and True Scientific, and coordinates freight for Southern California labs while shipping to buyers nationwide. Every unit carries the full manufacturer warranty.
Which ULT Freezer Brands Does Legacy Lab Supplies Carry?
Haier Biomedical
Upright and chest ULT freezers for biobanking, pharmaceutical research, and clinical sample storage.
Scientemp
American-made ULT and low-temperature freezers built for continuous laboratory duty.
True Scientific
Laboratory-grade freezers and refrigerators engineered for sample and reagent preservation.
What Temperature Range Do ULT Freezers Cover?
ULT freezers span -40°C to -86°C, with select models reaching -90°C. Within that band, upright and chest configurations are available with single or dual cascade compressor systems, and capacities from benchtop-adjacent units to 25+ cubic feet.
| Range | Typical Use |
|---|---|
| -40°C to -50°C | Reagents, enzymes, and samples that need colder storage than a standard freezer but do not require deep-cold preservation. |
| -70°C to -80°C | The common band for biobanking, cell lines, and vaccine storage. |
| -86°C to -90°C | Long-term repository storage where maximum sample stability is required. |
Are ULT Freezers Eligible for ENERGY STAR or California Rebate Programs?
ENERGY STAR maintains a certification category for laboratory-grade freezers, and several California utilities run rebate or incentive programs aimed at high-efficiency lab equipment. These programs exist and cover ULT freezers in general, but certification status and rebate eligibility vary by specific model, utility territory, and program cycle.
We do not promise or guarantee that any specific ULT freezer will qualify for ENERGY STAR certification or a utility rebate. Confirm current program terms and equipment eligibility directly with the certifying program or your utility provider before you purchase, and ask us for the manufacturer's efficiency documentation on the model you are considering.
How Is ULT Freezer Freight Handled in Southern California?
ULT freezers ship LTL freight due to their size and weight. Legacy Lab Supplies coordinates freight quotes and delivery scheduling for labs throughout Southern California and ships to buyers nationwide. Freight cost and lead time are confirmed on your quote before you place an order.
Upright vs. Chest ULT Freezers, Which Should I Choose?
Upright ULT freezers organize samples on shelves for easier access and a smaller footprint, which suits labs that open the freezer frequently. Chest-style units generally hold temperature better after a door opening and use floor space instead of height, which suits labs prioritizing sample stability over frequent access. The right choice depends on your lab layout, sample volume, and access pattern.
