What comes to mind when you hear the phrase Cold Preservation?

Food is probably near the top of the list.



Yes, yes and yes.

How about wood?

Ship wrecks?




Recovering sunken timber from the deep cold depths of Lake Superior has proven very rewarding. Logs originally cut over 100 years ago that were too water logged to float are now being recovered and are highly valued by architects, furniture makers, builders and musical instrument makers worldwide for their unique characteristics.







The cold deep waters of the Great Lakes (and other bodies of water) have also preserved shipwrecks for over 200 years.

Photographs, film and even books maintain their integrity and quality in cold storage







Seeds are cold stored and frozen in seed banks worldwide. Mechanical freezers and liquid nitrogen freezers are used to ensure the viability of all plant life.



For long term storage of some biological samples the preferred method is Vapor Phase Liquid Nitrogen Storage. The vapor phase (dry storage) of liquid nitrogen produces a storage environment in the -190°C range without liquid nitrogen contact. Studies have shown that at least two different viruses, Hepatitis B and Vesicular Stomatitis retain infectivity after suspension in liquid nitrogen. Vials or other storage medium can break, contaminating the liquid nitrogen and possibly contaminate the other samples in storage. Strict safety measures should be followed at all times to ensure the safety of the user should this occur.





Custom BioGenic Systems of Romeo, Michigan manufactures a wide range of liquid nitrogen freezers including Isothermal Vapor Phase Liquid Nitrogen Freezers, Controlled Rate Freezers, various dry shippers and dewars for industries that include life sciences, research laboratories, veterinarian, horticulture, pharmaceutical, industrial, scientific and medical, as well as cell and tissue banks.
