-86° Ultra Low-Temp Freezer HNZXIB 28L Lab Refrigerator Copper System

Description

Product Overview

The -86° Ultra Low‑temperature Freezer is engineered for demanding laboratory environments where precision, reliability, and energy efficiency are paramount. With a compact 28 L internal volume, the unit delivers ultra‑low temperatures suitable for preserving delicate biological specimens, cryogenic metal parts, and premium deep‑sea seafood such as tuna and sashimi. Its core refrigeration system utilizes a full copper tube evaporator and condenser, providing superior heat exchange performance and long‑term durability. The interior liner is crafted from 304 stainless steel, offering excellent corrosion resistance and easy cleaning, while the double‑door gaskets ensure a hermetic seal that prevents temperature fluctuations.

Designed with a single‑compressor architecture, the freezer minimizes the number of moving parts, resulting in a lower failure rate and reduced maintenance requirements compared to dual‑compressor models. The compressor operates continuously, delivering stable 24/7 cooling while consuming only 300 W of power, translating to less than 4 kWh per day. This low energy footprint makes the freezer an economical choice for laboratories that run multiple units around the clock.

The unit’s exterior dimensions of 22.44 × 21.56 × 30.9 inches and a weight of 102 lb provide a footprint that fits comfortably on standard lab benches or within dedicated refrigeration cabinets. A 120 mm thick insulation layer safeguards the internal temperature against external thermal influences, ensuring consistent performance even during harsh winter conditions. The freezer also features an intuitive digital control panel that allows users to set and monitor temperature with high precision, and an alarm system that alerts staff to any deviations from the set parameters.

Usage

This freezer excels in a variety of scientific and industrial applications. In biomedical research labs, it serves as a reliable repository for cell cultures, tissue samples, and reagents that require ultra‑low temperature storage to maintain viability and integrity. Cryogenic treatment facilities benefit from the freezer’s ability to achieve and sustain temperatures that facilitate metal hardening processes, extending the lifespan of critical components. Additionally, food science laboratories and gourmet culinary establishments can use the freezer to store high‑value seafood, preserving freshness and texture for extended periods.

Because of its energy‑efficient design, the freezer is well‑suited for continuous operation in environments where power consumption is a key consideration. Its robust construction and low failure rate make it a trusted asset in long‑term storage scenarios, where any temperature excursion could compromise valuable samples. The unit’s user‑friendly interface and clear temperature readout enable technicians to quickly verify conditions, reducing the risk of human error.

Whether placed in a dedicated cold‑room, a standard laboratory space, or a specialized research facility, the freezer integrates seamlessly with existing workflows. Its compact size allows for stacking or side‑by‑side placement with other equipment, optimizing lab real estate without sacrificing performance.
