Thermo Scientific TDE Series Ultra-Low Temperature Freezers are powered by H-drive and feature four upright models maximizing storage capacity from 30,000 to 60,000 2mL vials. The TDE Series is a sustainable and reliable solution with ultimate sample security and operational savings for every lab. Designed for daily usage, these ULT freezers recover cabinet temperature 20% aster after opening the door. A quiet sound output below 53 dBA enables the freezer to come out of the hallway and conveniently into the laboratory. Each unit meets ±10°C validation protocols at -80°C with strong peak variation and steady-state temperature variation. The natural hydrocarbon refrigerants reduce system operating stresses promoting outstanding reliability and worry-free sample protection.
