PHCbi | MDF-DU702VX TwinGuard ULT Freezer

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

The TwinGuard MDF-DU702VX -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 nitrogen or 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.

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 utmost confidence that they won’t be lost in the case of compressor failure.

Efficient Sample Storage

The combination of VIP PLUS vacuum insulation and enhanced cabinet design with an 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. Significantly extended time to react to any sudden mechanical failures and data logging is ideal for high-security applications such as pathogenic research.
