Aramus Single-Use Bag Assemblies For Cryogenic Temperature Compatibility

This application note explores the cryogenic temperature compatibility of the Aramus™ bag assembly material through freezing and drop testing after 24-hour minimum immersion in the liquid nitrogen (LN2) vapor phase.

Aramus 50 mL, 250 mL, and 500 mL bags were tested for frozen compatibility at LN2 temperatures (-196°C [-321°F]) by multiple freeze/thaw cycles and a single frozen drop test. In addition, the freeze rates and temperature profiles were monitored. All bags were exposed to above 25 kGy gamma irradiation prior to testing.
