These Labconco Fast Freeze Flasks are quick to handle and load, this flat borosilicate glass fast-freeze flask comes with a silicone rubber snap-on top to provide reliable, high-vacuum seals and eliminate risks of contaminants in samples. The vacuum grease also aids in eliminating contamination while also reducing spillage and sample loss.

The Fast-Freeze Flask features a wide mouth to load samples fast and a flat bottom to reduce spills and provide balance. They are compatible with all major brands of freeze-dry equipment. Fill the flask no more than one-third of the volume so that maximum surface area is attained. Purchase tops, bottoms and filter paper separately. Adapters are also required to attach flasks to freeze dry valves—40 and 80mL flasks use a 1/2 in. (1.3cm) adapter; while larger sizes use a 3/4 in. (1.9cm)
