MDF-DU302VX TwinGuard ULT Freezers (-86°C)

MDF-DU302VX TwinGuard ULT Freezers (-86°C)

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

The TwinGuard MDF-DU302VX -86°C Ultra Low Temperature Freezer meets the demand for safe, long-term storage of high-value materials.
Two independent refrigeration systems, combined with optional liquid nitrogen or liquid CO₂ back-up systems, provide unmatched protection in the marketplace.

With two independent refrigeration systems, TwinGuard freezers maintain a reliable and uniform -86ºC ultra-low temperature environment.
If one cooling system fails unexpectedly, the other circuit keeps samples safely around -70ºC until service is arranged.

Ultimate Sample Protection

The Dual Cooling System ensures the highest level of protection through two independent refrigeration systems.
If one system fails, the other maintains the freezer in the -70°C range, protecting valuable and irreplaceable samples even in the event of compressor failure.

Efficient Sample Storage

VIP PLUS vacuum insulation and enhanced cabinet design with an insulated outer door ensure optimal temperature uniformity, while reduced wall thickness maximizes storage capacity.

Flexible Shelf Layout

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

Intelligent Interface

The EZlatch makes sample access easier.
A color LCD touch panel allows full user control, even with gloved hands, and a USB port enables convenient data transfer to a PC.
Extended response time to mechanical failures and data logging functions make it ideal for high-security applications such as pathogenic research.
