Custom Biogenic Systems

Dry storage in liquid nitrogen

Custom Biogenic Systems is a leader in the design and manufacturing of laboratory products and supplies. By understanding the needs of the biotechnology industry, Custom Biogenic Systems provides superior laboratory freezers and complete rack systems that support veterinarian, horticulture, pharmaceutical, industrial, scientific and medical research laboratories, as well as cell and tissue banks.

Liquid nitrogen freezers


Storage in liquid nitrogen can make vials shrink. This may cause liquid nitrogen to seep into the vials, which on re-warming, expand and subsequently explode as nitrogen vaporizes inside the vials. Dry storage eliminates this possibility. Also, the design of CBS systems provides added user safety by eliminating contact with or splashing of liquid nitrogen.


Cross Contamination

Studies have shown that viral, bacterial and fungal pathogens can survive after suspension in liquid nitrogen. Infected samples can cross contaminate other samples in the same liquid nitrogen tank. Dry storage eliminates the possibility of cross contamination.
