Protocols can be based on ‘sample temperature event’ triggering, which combined with the fast cooling rates and forced laminar flow of the system, ensures high efficiency cooling at the fusion temperature. This enables efficient latent heat removal, creating optimum sample viability post thaw. The easy access front opening door is closed via a 3 point closure system, ensuring a leak free seal which helps to prevent the door freezing closed at low temperatures; additional protection is provided by heated door seals. The freezer’s control system is operated via a two button process which helps prevent accidental running of a wrong protocol. This also helps with rapid user training and process verification. The system can also be operated via Planer’s software application - DeltaT™ which then offers multiple protocols and data viewing on-line, as well as data capture and storage for validation.
