The Haier DW-86L51J is a compact, front-loading -86°C ultra-low temperature freezer sized to slide under a standard laboratory bench. With 51 L (1.8 cu ft) of upright storage, an upright cabinet just tall enough to fit beneath a counter, and a standard 115V/60Hz plug, it brings true -80°C storage to point-of-use workflows — PCR benches, tissue-culture suites and satellite labs — where floor space for a full-size freezer simply is not available.

Application Profile
The DW-86L51J exists to solve a placement problem. Most -86°C freezers demand a dedicated footprint and clear overhead, but many workflows only need to store a working subset of samples close to the bench. At an undercounter height with a front-loading door, this model tucks into cabinetry or under a counter and still delivers the full -40°C to -86°C range on a normal 115V circuit — no 208V receptacle or dedicated cold room required.
Inside, a single stainless-steel adjustable shelf and one insulated inner door organize up to 30 2-inch cryoboxes, and a 25 mm side porthole accepts an independent temperature probe. Despite the small cabinet, it carries the full Haier alarm suite — high/low temperature, power failure, door ajar, hot condenser, low battery, sensor error and high-ambient — plus USB and remote-alarm outputs, so a benchtop unit is monitored to the same standard as a central freezer.
Frequently Asked Questions
Does the DW-86L51J really reach -86°C on a standard outlet? Yes. It reaches a cooling performance of -86°C (range -40°C to -86°C) on a standard 115V/60Hz supply, making it easy to site without electrical upgrades.
Will it fit under a lab bench? Yes — it is an upright, undercounter, front-loading design intended to be placed beneath a standard counter to save floor space.
How many samples does it hold? Up to 30 standard 2-inch cryoboxes, on one adjustable stainless-steel shelf behind a single inner door.
Is it monitored like a full-size ULT freezer? It carries the full alarm package (high/low temperature, power failure, door ajar, hot condenser, low battery, sensor error, high ambient) and provides USB, remote-alarm and RS232/485 outputs.
Ordering & Configuration
The DW-86L51J is a capital purchase. Add it to a quote and a Legacy Lab Supplies specialist will confirm dimensions against your bench opening, ventilation clearance and delivery details, and route factory warranty registration. Lead time is quoted per configuration; contact us for current availability.
Choose the DW-86L51J when you need genuine -86°C storage at the point of use and floor space is the constraint. If your sample volume is growing beyond ~30 boxes, step up to the freestanding DW-86L100J or the ENERGY STAR DW-86L578J for full-size upright capacity.
