MDF-DC700VX-PE TwinGuard ULT – A Chest Freezer for Storing High Value Samples




TwinGuard -86 ˚C MDF-DC500VX chest freezer delivers the unsurpassed level of safety and sample security that is critical for valuable biological samples alongside exceptional ease of use and data monitoring.

Two independent refrigeration systems offer 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.

Valuable Sample Storage

Securely store valuable and irreplaceable samples with the upmost confidence that they won’t be lost in the case of compressor failure.

Significantly extended critical time to react to any sudden mechanical failure. Ideal for high security applications.
