Technical Information
Average cooling rates, from 4°C to -40°C (39°F to -40°F), observed with Aramus bags stored in cassettes. Data on rates shown in use with different freezers prior to storage in LN2 temperatures.

Cassettes shown to increase robustness by maintaining bag integrity post-LN2 vapor phase storage. Aramus bags in cassettes were frozen in LN2 vapor for 24 hours and then subjected to 12” drops three times:
| Bag size | Fill volume | Drop test result |
| 20 mL | 20 mL | Pass (8/8) |
| 50 mL | 50 mL | Pass (8/8) |
| 100 mL | 100 mL | Pass (8/8) |
| 250 mL | 200 mL | Pass (8/8) |
| 500 mL | 350 mL | Pass (8/8) |
Note: Entegris has not performed performance-specific testing on 36 ml or 80 ml cassettes, but views performance challenges as low risk due to relative geometries that are similar to larger and smaller cassette sizes. Entegris has performed limited performance-specific testing on 1 L or 2 L cassettes. Please contact your Entegris account manager for more information on these sizes.
