Freeze drying

Freeze drying for preservation

Preserve materials through freeze drying (also known as lyophilisation) by first freezing them with liquid nitrogen, and then dehydrating them in a vacuum so that the frozen water sublimes directly from liquid to gas.

Air Products advantage

Air Produce can provide a range of nitrogen cooling solutions to help you:

• Improve performance
• Reduce costs
• Optimise your freeze drying applications

Low temperature storage

This is the best way to preserve materials that cannot withstand oxygen or heat, or materials that lose activity as a liquid – enabling them to remain highly stable in their dehydrated form. Examples include antibiotics, vaccines, antibodies, protein, enzymes, blood products, bacteria, viruses, and fine chemicals.
