Product description

Ultra low temperature freezer with multi-stage refrigeration, maintaining -80°C for biobanking and molecular diagnostics storage.

The Harris Classic HLT-21V-85E29 is a -80°C ultra low temperature freezer designed specifically for laboratory environments requiring stable, reliable sample preservation. It incorporates a multi-stage refrigeration system utilizing environmentally optimized refrigerants: R-404A (42 oz), R-134A (10 oz), R-23 (4.4 oz), and R-290 (0.8 oz), ensuring sustained cryogenic temperatures essential for molecular diagnostics, synthetic biology research, and bioprocessing workflows.

Key technical features include:

  • Voltage operation at 208/230 V with a 9 A amperage rating.
  • Multiple internal storage drawers (five total) offering organized and efficient sample management, suitable for biobanking and cell imaging applications.
  • High and low test pressures rated at 400 psig, supporting robust multi-stage refrigeration performance.
  • Ideal for research fields including biotechnology, biomedical engineering, and clinical diagnostics, where maintaining specimen integrity at ultra-low temperatures is critical.

This freezer is widely adopted in biopharmaceutical production pipelines and gene editing laboratories for its dependable temperature stability and optimized storage capacity, making it a key asset in synthetic biology and molecular cloning workflows.

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.
