CBS 2101 Controlled Rate Freezer
Optimized freezing
The CBS 2101 Controlled Rate Freezer is designed to freeze samples at a controlled, reproducible rate. This helps protect sample integrity and viability during the transition to long-term cryogenic storage.
Unlimited programming capability
Limitless programmes can be set to advance sample or chamber temperature, with up to 30 data fields available for each run. Six common pre-set programmes are provided as standard.
Temperatures can be set between +50°C and -180°C, with programmable cooling rates from 0.01°C/min to 99.9°C/min. Final temperatures can also be held after completion of the freezing programme.
Controller and sample security
The CBS 2101 Controlled Rate Freezer comes equipped with a dedicated laptop controller and 2100 programming software for user convenience. The Windows-based operating system allows clear display of multi-colour freeze run graphs and simple programming.
Individual user accounts and passwords can be set up with different access levels. When security is enabled, a full audit trail can track freeze runs, user changes, profile changes, invalid logins and system lockouts after repeated failed attempts.
Key benefits
Increased viability
Supports high viability for stem cell and IVF applications through controlled and reproducible freezing.
Flexible storage
Multiple rack types and unlimited programming support a wide variety of research sample formats.
Traceable results
Freeze data can be saved, printed and reviewed to support documentation and quality workflows.
Diverse sample types
Each CBS 2101 Controlled Rate Freezer comes with a choice of cane, vial or bag canister rack as standard, with additional racks available as required. Optional sample probes support vial, straw and blood bag applications.
