Lyph-Lock Flasks simplify your lyophilization procedures
because they have only three pieces per flask — a high
strength borosilicate glass top and bottom with a silicone
rubber ring seal. The unique wide-mouth design helps you
load samples easily and lyophilize efficiently.
How to select Lyph-Lock Flasks for
your Freeze Dry System
Select the Lyph-Lock Flasks based on your sample sizes.
Flasks should be filled to no more than one-third of their
volume so that maximum surface area is achieved and effi-
cient lyophilization is ensured. A complete Lyph-Lock Flask
includes a glass top and bottom and a rubber ring seal. Tops,
bottoms and seals are available separately as replacement
components. Adapters are required to attach flasks to freeze
dry valve ports.
