Ultra-Low Temperature Freezer LTF Twin

LTF Twin Freezer

LTF Twin Ultra-low temperature freezers with double cooling technology offer a maximum of safety for your high-quality samples. In addition to the exceptional ease of use and data monitoring, the Dual Cooling System provides the highest level of protection by using two independent cooling systems.

Should a cooling system fail unexpectedly, the other can maintain the freezer´s temperature uniformly in the range of -70°C.
The freezers are managed and monitored by an integrated microprocessor controller with a comprehensive alarm system and diagnostic functions.

Certified as a Class IIa medical device (93/42/EWG and 2007/47/EU).
