Ultimate Sample Protection

TwinGuard® ultra-low temperature freezers feature a dual cooling system with two independent compressors and circuits. In the event of a malfunction in one circuit, the second circuit seamlessly takes over, sustaining the in-chamber temperature as low as. -75°C, reducing the risk of sameple loss. Designed for reliability in high-stakes environments, TwinGuard freezers ensure continuous protection for irreplaceable research materials.
