MDF-DC500VX TwinGuard ULT Chest Freezer

The most secure ultra-low temperature freezers for the storage of 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."
 

Improved Temperature Performance

TwinGuard chest freezers maintain even better temperature stability and uniformity during routine door openings than equivalent upright models as less cold air leaves the freezer while the door is open.
