All-Glass Vacuum Filter Holder
The all-glass vacuum filter holder is suitable
for membrane filters with a diameter of
50 mm (or 47 mm). It comes complete with
a vacuum-resistant glass flask, which you
can use to retain the filtrate.
A 6 mm wide, non-ground glass rim, located
above the ground glass neck of the filtrate
flask, prevents contamination of the filtrate
by contact with the ground glass area
(e.g., by grease) while it is being poured out.
The filter support consists of a glass frit
in a PTFE ring. All other parts of the filter
holder that come in contact with filtration
medium are made of glass.
The glass funnel and glass base are held
together securely by a metal clamp.
A centering rim on the filter support makes
it easy to position the funnel and prevents
the inserted membrane filter from being
displaced.
