Our most secure ultra-low temperature freezers for the storage of high value samples

The TwinGuard MDF-DU702VX-PE -86°C Ultra Low Temperature Freezer satisfies an industry demand for safe, long-term storage for the most high-valued materials. Two, independent refrigeration systems, combined with optional liquid CO2 back-up systems, offer a circle of protection unmatched in the marketplace.

With two independent refrigeration systems TwinGuard freezers maintain a reliable and uniform -86ºC ultra low temperature environment. Should one cooling system suffer an unexpected failure, the other circuit will keep irreplaceable samples safely around -70ºC until service can be arranged.

Cleanroom Classification

To ensure that our equipment can be trusted as an essential tool for cleanroom applications, we have invested in the classification of our flagship cold storage and cell culture incubators. The MDF-DU702VX-PE is ISO 14644-1 part 14 Classified and falls in ISO Class 6.0. Find out more in the brochure at the download section on this page.

Ultimate Sample Protection

The Dual Cooling System offers the highest level of protection through the use of two independent refrigeration systems. If one system unexpectedly fails the other can maintain the freezer in the -70°C range. Securely store valuable and irreplaceable samples with the upmost confidence that they won’t be lost in the case of compressor failure.

Efficient Sample Storage

The combination of VIP PLUS vacuum insulation and an enhanced cabinet design with insulated outer door, ensures optimum temperature uniformity, while the reduced wall thickness maximizes storage capacity.

Flexible shelf layout

Multiple shelf configurations allow a variety of storage options. Organize your samples by transferring your current inventory racks.

Intelligent Interface

The EZlatch makes access to stored samples even easier. A colour LCD touch panel allows full user control, even with gloved hands, while the USB port makes transferring logged data to a PC convenient.
