Ultra Low Temperature Freezer, Ultra Low Deep Freezer

ultra low deep and temperature freezer

Ultra low deep and temperature freezer:

True  -86°C Ultra Low Deep Freezer itself, the samples stored in it are the most important issue for a customer. For this reason Roch only chooses the most reliable components available in the world. The reliable proven compressors are Used in a unique cascade system with very low pressures and a completely sealed cooling system.
The Roch Ultra Low Freezer is a very durable and reliable system with an extremely low noise level.
This low noise level is created by a very efficient and effective use of the cascade compressor system with non CFC refrigerants.Temperature controller, Lock and Alarms are built in features.



Roch Ultra Low Deep Freezer is widely used in Universities, microbiology, genetic, biotech, Hospitals  Also used for preservation of red blood plasma, white blood cell, skin, bone, bacteria, semen, biomedical product in small medium and large blood centers.

Deep Freezer ideal laboratory freezer to provide a perfect freezing environment for the preservation of vaccines, blood plasma, test samples, specimens at desired temperature (Available in various Models i.e.,-70ºC,-80ºC,-86ºC.)
