MDF-DU702VX TwinGuard ULT Freezers (-86°C)

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 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, provide unmatched protection.

If one cooling system fails, the other maintains approximately -70°C, ensuring sample safety until service is arranged.

Ultimate Sample Protection

The Dual Cooling System ensures maximum protection with two independent refrigeration circuits. Even in case of compressor failure, the freezer maintains -70°C, safeguarding irreplaceable samples.

Efficient Sample Storage

VIP PLUS vacuum insulation and optimized cabinet design ensure temperature uniformity and maximize storage capacity by reducing wall thickness.

Flexible Shelf Layout

Multiple shelf configurations allow flexible storage options and easy organization of existing inventory racks.
