Description
The Kryo 750 is an integrated controlled rate freezer for cryopreservation of larger volume samples or samples in larger numbers.
The controlled rate freezer is designed for freezing of samples in bags, vials and straws.
It has a simple 2 button operation with standard PC software to enable password protected multiple protocols. A forced laminar flow cooling system ensures most efficient, even cooling and the machine has Top or Front opening for easy loading. Heated door seals prevent the lid freezing shut at cryogenic temperatures.
Protocol stage “trigger on sample”, or chamber temperature, or time and the inner chamber is removable for sterilisation. The 750 has a Comms port - for PC connection and has flexible and fast cooling rates.
This controlled rate freezer is designed for freezing of bigger volumes of samples in bags,vials and straws. It has a simple 2 button operation to prevent the user accidently running the wrong protocols. By using our PC software, DeltaT, enables password protected multiple protocols, online data-viewing, capture and storing for validation.
Batch freezing is possible using our DeltaT software. Large sample numbers can be deposited in different machines with the subsequent freezing profile for allsamples being displayed on the same graph.
A forced laminar flow cooling system ensures efficient, even cooling. The machine has top or front opening for easy loading.
The heated door seals prevent the lid from freezing shut at cryogenic temperatures. Protocol stage“trigger on sample”, or chamber temperature, or time.
The inner chamber is removable for sterilisation. The 750 has a Commsport for PC connection and hasflexible and fast cooling rates.

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.
