Ultra-low temperature freezer with 729L capacity, precise microprocessor control, and dual refrigeration circuits for biotech storage.
The PHCbi MDF-DU702VHS1-PJ is a robust ultra-low temperature freezer designed for advanced biotechnology and biomedical storage applications requiring stable deep freezing performance. It features a large 729-liter capacity with durable painted steel interior and exterior and includes three stainless steel shelves capable of supporting 50 kg each, ideal for high-density bioprocessing sample storage such as molecular diagnostics and biomanufacturing.
Key specifications include a dual refrigeration circuit utilizing eco-friendly hydrocarbon refrigerants (non-fluorocarbon) with independent compressors (750 W each for high and low temperature sides) enabling rapid and reliable cooling down to -85°C, essential for gene editing workflows and cryopreservation in synthetic biology research. The freezer control system is a microprocessor-based unit with LCD touchscreen display providing precise temperature regulation from -85°C to -50°C, suitable for live-cell imaging sample preservation.
Safety and monitoring features include multiple alarms for high/low temperature thresholds, filter status, door open alerts, and power failure notifications with delayed buzzer activation and remote alarm outputs, critical for continuous monitoring in clinical diagnostics and bioprocessing pipelines. Enhanced insulation combines rigid polyurethane foam with a 20 mm vacuum insulation panel (VIP PLUS), reducing thermal loss and energy consumption.
Physical dimensions (103 cm W × 88.2 cm D × 199.3 cm H) and weight of 279 kg make it suitable for laboratory environments requiring stable ultra-low temperature conditions. This used unit is sold as-is; performance may slightly differ from new but maintains essential functions for demanding biotechnology and biomedical research applications.
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.
