32L super-insulated cryogenic dewar for efficient liquid nitrogen storage and dispensing in labs and medical use.
The Quality Industries QMM-4 Marinator is a laboratory-grade cryogenic liquid nitrogen dewar designed for secure storage and controlled dispensing of liquid nitrogen. This model features a 32-liter net capacity with a low static evaporation rate of 0.22 L/day, ensuring efficient liquid nitrogen conservation essential in molecular diagnostics, biotechnology, and biomedical engineering workflows.
Key technical specifications include:
This cryogenic vessel is critical for bioprocessing applications, cell imaging protocols, and synthetic biology research requiring stable, long-term cryogenic preservation. The super-insulated design minimizes nitrogen boil-off, making it a reliable component in biomanufacturing setups and molecular cloning workflows where consistent temperature control is vital. Widely adopted in both medical facilities and advanced research laboratories, the QMM-4 Marinator supports diverse applications in live-cell imaging and fluorescence analysis by maintaining ultra-low temperatures with minimal evaporation loss.
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.
