Ultra-low temperature freezer MDF-DU702VHS1-PJ with 729L capacity and -85°C cooling for bioprocessing storage
The PHCbi MDF-DU702VHS1-PJ is an ultra-low temperature freezer designed for biomedical and biotechnology laboratory applications requiring reliable cryogenic storage. Featuring a large 729-liter capacity, this ultra-low temperature freezer operates down to -85 °C, using a dual refrigeration circuit with hydrocarbon refrigerants compliant with non-fluorocarbon environmental standards. The unit is equipped with thick vacuum insulation panels and rigid polyurethane foam combined for superior thermal efficiency. It includes a microcontroller-based temperature control system with precise LCD touchscreen display, alarms for high/low temperature, door status, filter alert, power failure, and battery backup to ensure critical sample integrity. The physical design incorporates painted steel plates for exterior and interior durability, stainless steel shelves rated for 50 kg each, and multiple measurement ports for sensor integration. Mounted on leveling casters, it facilitates safe and stable placement in laboratory environments.
Ideal for advanced biotechnology workflows involving molecular diagnostics, bioprocessing, and biomanufacturing, this freezer supports stable cryogenic storage essential for live-cell preservation, gene editing sample storage, and long-term reagent conservation. Its reliable performance and comprehensive alarm system make it critical for maintaining the cold chain in biopharmaceutical production pipelines and synthetic biology research environments. Sold as used, the unit is provided as-is with condition-specific considerations impacting performance relative to new units.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
