Flask-mounted freeze-drying loads samples into individual dry flasks that attach to the freeze dryer's manifold, where sublimation removes water under vacuum at low temperature. The 120 mL dry flask is the small-batch size for concentrated or precious samples, and a 5-pack lets an operator run several flasks per cycle or keep spares on hand for turnaround. These are the manufacturer's matched glassware for the DC401, so the joints seat correctly and hold vacuum.
Pair the flasks with the dry flask caps (212570) for storage and transfer, and choose the 250 mL size (212821) for larger volumes.
