Sophisticated Refrigerator, Freezer Systems Provide Control

Refrigeration has long been a critical component of myriad clinical and biological research applications. Nowhere is the need for precision refrigeration and freezing in greater demand than in laboratories that handle blood, blood products, DNA, enzymes, and tissue samples, and in those involved in human reproductive technology.

CRYOGENIC FREEZER: Revco Scientific’s Ultra-Low freezer can chill to -86°C

While the use of refrigeration is common in laboratories, increasingly sophisticated systems are in demand to meet evolving clinical and cryobiological applications. "These are the areas where there is a lot of work under way," says Steve Brothman, vice president and general manager of Southland Cryogenics Inc., a manufacturer of liquid nitrogen units in Carrollton, Texas. Researchers and clinicians want greater control over the processes of chilling and superchilling specimens, he points out. State-of-the-art systems involve computers and software packages, microprocessors, robotics, and a variety of exotic refrigerants.
