Fast-Freeze® flasks for FreeZone® Freeze Dry Systems are designed to be easier to handle, faster to load, and more convenient to use in the laboratory for freeze drying.

• Compatible with all major brands of freeze drying equipment, including Labconco and Virtis™

Flask adapters attach to Fast-Freeze® flasks for connection to valve ports on drying chambers or manifolds for freeze dry systems. Choose borosilicate glass or stainless steel, straight or 45° angle adapters in 0.63cm (¹/₄") and 1.9cm (³/₄") diameters.

Flat bottom, high-strength borosilicate glass flask withstands high heat and deep vacuum. Uniform glass walls maximize heat transfer while maintaining structural strength. Wide-mouth design provides full access to entire inner diameter of glassware for easy loading and cleaning. Silicone rubber snap-on tops provide reliable high-vacuum seals. Flasks should be filled no more than one-third of the volume so a maximum surface area is achieved and efficient lyophilization is assured.

Flask adapters attach to Fast-Freeze® Flasks for connection to valve ports on drying chambers or manifolds for freeze dry systems. Choose borosilicate glass or stainless steel, straight or 45° angle adapters in 0.63 cm (¹/₄") and 1.9 cm (³/₄") diameters.

Flask Holders help to prevent sample melt back. They allow a small Fast-Freeze Flask Bottom containing the sample to be placed inside a larger Fast-Freeze Flask so that the vacuum surrounding the sample insulates it from the room atmosphere. Stainless steel. Flasks not included.
