Fast-Freeze Flasks are specially designed to be easier to
handle, faster to load and more convenient to use than other
freeze dry glassware now in your laboratory. Compatible
with all major brands of laboratory freeze dry equipment,
Fast-Freeze Flasks eliminate the risk of contamination from
vacuum grease, reduce spillage of valuable samples and
require no washers, gaskets or retainers.
How to select Fast-Freeze Flasks for
your Freeze Dry System
Select Fast-Freeze Flasks based on your sample sizes. Flasks
should be filled no more than one-third of their volume so
that maximum surface area is achieved and efficient
lyophilization is assured. A complete Fast-Freeze Flask
includes a rubber top, glass bottom and a supply of filter
paper. Tops, bottoms and filter paper are available separate-
ly as replacement components. Adapters are required to
attach flasks to freeze dry valve ports.
Adapters
Add the Adapters for connecting
the Fast-Freeze Flasks to the valve
ports on your drying chamber or
manifold. Choose borosilicate glass
or stainless steel adapters in 1/2"
and 3/4" diameters.
