Product description

Ultra low temperature freezer -80°C, 728L capacity, dual refrigerants R290/R170, advanced alarms, digital control panel.

The Haier DW-86L728J ultra low temperature freezer offers reliable cryogenic storage down to -80°C with an effective volume of 728 liters, making it essential for biomedical research, molecular diagnostics, and biomanufacturing workflows. This -80°C freezer features a dual refrigerant cooling system using environmentally friendly R290 (130g) and R170 (95g) to ensure efficient and stable temperature maintenance.

Key technical specifications include:

  • Voltage: 120V, 60Hz operation suitable for laboratory and clinical environments
  • Power rating: 18A rated current, optimized for energy efficiency in continuous use
  • Temperature control: Digital control panel provides precise temperature setting and monitoring
  • Alarm systems: Multi-parameter alarms cover high/low temperature deviation, power failure, door ajar, probe failure, low battery, hot condenser, and high ambient temperature, ensuring sample integrity and operational safety
  • Construction: Includes three internal shelves to maximize organized sample storage for cell imaging reagents, synthetic biology materials, and cryopreserved bioproducts
  • Weight: 345 kg, indicating a robust build for stable, vibration-free operation

This ultra low temperature freezer is widely used in biotechnology laboratories, clinical diagnostics, and bioprocessing facilities where maintaining strict storage conditions for sensitive biomaterials is critical. It is particularly suited for molecular biology research, live-cell imaging sample preservation, and synthetic biology projects requiring stable deep-freeze environments. The Haier DW-86L728J supports demanding workflows by combining durable construction with advanced temperature control and comprehensive alarm functions tailored for modern laboratory cold storage needs.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
