Product description

Ultra-low temperature freezer -86°C to -40°C; 19.4 cu ft storage; 40,000 vial capacity; energy-efficient for biotech labs.

The Thermo Scientific TSX40086FA Ultra-Low Temperature (ULT) Freezer is engineered for secure cryogenic storage in biotechnology, molecular diagnostics, and biopharmaceutical research. Featuring a temperature range of -40°C to -86°C, it maintains precise thermal stability with a peak variation below 3.6°C, critical for preserving sensitive biological samples in live-cell imaging and synthetic biology workflows.

Key technical features include:

  • Dual-stage natural refrigerants (R290 and R170 + R290 mix) supporting eco-friendly, energy-efficient operation through the V Drive adaptive control system.
  • Robust vacuum insulation and water-blown polyurethane foam construction for optimal insulation and reduced warm-up times.
  • Spacious interior volume of 19.4 cubic feet, accommodating up to 400 two-inch boxes or 40,000 2 mL vials—ideal for large-scale bioprocessing and biomanufacturing sample storage.
  • Onboard data center with real-time monitoring and touchscreen interface: Enables comprehensive temperature logging, system diagnostics, and event history accessible via USB and Smart Vue cloud compatibility, facilitating remote monitoring central to molecular cloning and clinical diagnostics.
  • Ergonomic design with easy-to-open handles and shelf-level placement that enhance loading ergonomics for frequent sample access common in gene editing studies.
  • Quiet operation suitable for laboratory environments focused on neuroimaging and fluorescence analysis.

With external dimensions of 29"x38"x78" and weighing 679 lbs, this model runs on standard 115 V, 60 Hz power, making it a reliable and energy-conscious choice for biorepository storage and other critical biomedical engineering applications. Its manual defrost system and rapid door-opening recovery support uninterrupted workflow in high-demand research settings.

This unused Thermo TSX40086FA unit is fully inspected and supported by standard warranty coverage, ensuring dependable performance for your laboratory’s ultra-low temperature 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.
