The PHCbi MDF-DU702VHS1-PJ is a high-capacity ultra-low temperature freezer designed specifically for biomedical and biotechnology laboratories requiring reliable deep-freezing solutions. It features a robust 729-liter storage capacity within a durable painted steel enclosure and interior suitable for clinical diagnostics, synthetic biology, and molecular diagnostics workflows.

Key specifications include:*

  • Cooling performance down to -85°C with a temperature control range of -85°C to -50°C, optimized for long-term preservation of biological samples in bioprocessing and biopharmaceutical production pipelines.
  • Dual refrigeration circuits employing environmentally friendly hydrocarbon refrigerants (HC) ensuring efficient and eco-conscious cooling with natural convection cooling technology.
  • Constructed with rigorous thermal insulation: rigid polyurethane foam combined with a vacuum insulation panel (VIP PLUS 20 mm) to enhance thermal retention and reduce energy consumption.
  • Equipped with a microcomputer controller and a touch panel LCD display for precise temperature monitoring, essential in gene editing and cell imaging environments.
  • Critical safety features include multi-level alarms for high/low temperatures, door ajar status, power failure, filter status, and self-diagnosis capabilities with remote alarm outputs, enhancing lab operational reliability.
  • Designed with three heavy-duty stainless steel shelves each supporting 50 kg, multiple measurement and port openings for customized probes and sampling, and a secure cylinder lock system.
  • The freezer includes four casters with leveling bolts allowing for ease of installation and stability in high-demand laboratory settings.

This unit's combination of advanced alarm systems, dual cooling circuits, and precision control makes it indispensable in molecular biology research, cell imaging labs, and biomanufacturing environments, supporting the stringent temperature requirements necessary for live-cell imaging, biological sample storage, and molecular diagnostics workflows. Sold as used, it is offered as-is without guarantees that original manufacturer specifications will fully remain, therefore recommended for labs equipped to perform detailed pre-purchase validation.

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?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
