Single Stage Glass Impac-
tor Glaxo (EP App. A)
The unit operates on the principle of liquid im-
pingement to divide the dose emitted from the
inhaler into the non-respirable dose impacting
on the mouth and oropharynx wich is swallowed
and the remaining respirable dose.
The apparatus is relatively simple, easy to use
and rugged in construction and is ideal for rou-
tine Quality Control applications. The Glass
Single Stage Impactor comes complete with
base plate and appropriate clamps, bossheads
and fittings as standard. 70-907-0001

Single Stage Metal
Impinger Fisons
(EP App. B)
The principle of operation is similar to that of
the glass impinger in that the unit splits the
aerosol cloud into the respirable fraction that
effectively passes through to the final filter
stage and the non-respirable fraction that is
trapped in either the throat or on the sintered
glass disc of the stage plate. The Metal Single
Stage Impinger comes complete with base
plate and appropriate clamps, boss heads and
fittings as standard. 70-908-0001
