  1. Isothermal-190°C Dry Storage Freezer

  2. Isothermal Dry Storage Freezers • CBS Isothermal Freezers feature a patented liquid nitrogen jacket to provide uniform storage temperatures in the -190°C range, free from liquid nitrogen contact. • This innovative design eliminates the risk of cross-contamination through liquid nitrogen and the need for additional packaging to protect valuable cells and tissue. • With minimal temperature gradient, the full internal volume of each freezer is available for storing samples at liquid nitrogen temperatures making the most efficient use of available capacity. • CBS Isothermal Freezers also provide added user safety by eliminating contact or splashing of liquid nitrogen.

  3. Temperature Uniformity • Patented design including liquid Nitrogen jacket and vents cools samples by conduction via internal surfaces and by convection though vents. • The result is exceptional temperature uniformity which allows the whole freezer capacity to be utilized saving space and money. • Circulation of vapor also results is less cold air loss during lid opening and improved visibility.

  4. Temperature Uniformity

  5. Temperature Uniformity

  6. Temperature Uniformity Increased temperature safety zone from -130°C (Tg) compared to conventional vapor phase storage allows the whole freezer capacity to be utilized saving space and money. ~ -120C ~ -190C ~ -195C ~ -195C Isothermal Conventional Vapor Storage

  7. No Liquid Nitrogen Contact • CBS Isothermal Freezers are cooled by a patented liquid Nitrogen jacket and vents which direct vapor into the storage area. • There is no liquid Nitrogen in the storage area. • This eliminates the risk of cross-contamination through liquid nitrogen and the need for special packaging. • The Isothermal design also provides added user-safety eliminating contact or splashing of liquid Nitrogen.

  8. IVF inventory System • Specialized IVF storage system makes use of the entire freezer • 3-level carousel system with retrieval tool for convenient use • Built-in work area means no samples are exposed to ambient aire temperature when working with goblets/straws. • 2448 Goblet Capacity • 24,448 Straw Capacity (each Goblet holding 10 straws • Goblets and straws not included.

  9. Series 2300 Auto-Fill and Monitor System • The Series 2300 Auto-Fill and Monitor System provides sample security and ease of use. • System Status Display. • Programming of LN2 Auto-Fill Levels and Cycles. • Start/Stop Fill. • Comprehensive Alarm System with Remote Alarm Contact. • Output Data to PC / Printer.

  10. Series 2300 Auto-Fill and Monitor System • Sample Security – Alarm Functions • Visual and Audible alarms for: • High and Low LN2 Level in jacket. • Temperature Deviation • LN2 Supply • Sensor or Valve Abnormality • Remote Alarm Terminal (NC/NO) for connection to a central alarm system or auto-dialler. Operates on: • Alarm condition • Power failure • Sample Security - Construction • Lid Lock • Key Pad Lock
