Isothermal Carousel LN2 System

Isothermal Carousel LN2 System

Biolife Solutions "Isothermal" Liquid nitrogen vapor storage system allows frozen sample storage at liquid nitrogen temperatures without liquid nitrogen contact. This innovative design provides storage temperatures in the -190 degree Celsius range with absolutely no liquid nitrogen in the sample storage space.

The PATENTED system totally eliminates the need to submerge any type of sample in liquid nitrogen. Each vapor storage system includes the advanced 2301 auto-fill / monitoring control to provide security and ease of operation.

Four vapor storage systems are available, with sample storage capacities from 16,800 to 42,000 vials of 2ml or 434 to 2,400 blood bags of 25 ml. An extensive selection of inventory racks or bag canisters and frames are available to complete the system. Custom configurations can also be designed to meet any requirements.

Salient Features:

  • Stores samples at liquid nitrogen temperatures with no liquid nitrogen contact 
  • Dry storage totally eliminates the risk of cross contamination.
  • Added user safety by eliminating liquid nitrogen contact or splashing of Liquid Nitrogen.
  • 2301-ST Smart Touch Controller with 6" Touch screen display to easily set temperature controls and display settings
  • Programmable Lid Alarm to alert when lid is left open for user specified time
  • Global Remote Alarm - dry contact that switches during any alarm condition
  • Two-Level temperature display option
  • 0-5V or 4-20mA output signals for connecting to EMS/BMS or third party independent monitoring systems
  • Data Log - Print or display Temp. A, Temp. B and level with date and time stamp using Thermal Printer
  • Utilize the entire storage space; no space lost to bulky platforms.
  • Vapor circulation provides better visibility in the storage area, Increased Interior Visibility
  • Fallen samples can be retrieved using Cryo Tongs
  • Minimal Interior Temperature Gradients
  • Higher storage capacity than other carousel-type freezers.
  • Square lid opening allows access to square racks.
  • Hatch-style lift off lid with built in holder
  • Rotation of the carousel by the unique ratchet handle on top of the freezer reduces operator hazard.
  • It is easy to access one rack at a time.
  • No unnecessary exposure to room temperatures helps to maintain critical temperature stability.
  • Square lid opening allows access to square racks and helps reduce LN2 consumption.
  • Includes 2301 Controller to log Temperature and Alarm data
  • Security lock to prevent unauthorized access to samples and the performance parameters
  • Caster mounted, Round Space Saving Design
  • An extensive selection of standard inventory racks or canister and frames are available to complete the system (to be ordered separately).
