Ampoule Testing Apparatus
polarizing filters, for rendering foreign matters clearly visible on dark
testing apparatus integrates a light casing (1) being equipped with a
100-watt opal glass lamp (2) and a light scattering opal glass plate (3).
In order to prevent the heating of the polarizing filters being used under
conditions of continued service which must whenever possible not be
reaching more than 70°
Centigrade, mounting of filter (4) which is
being held in a heat insulating synthetic material frame, allows
for a distance in front of the light casing. The second filter (5) which
is held in a metallic mount (6) being right in front of magnifying lens
(7) permitting twofold magnification renders it possible that a rotary
motion of 90 degrees is being realized out of the polarization plane.
Frame (6) is adjustable in the longitudinal direction for the purpose of
focussing what is intended to be magnified. The testing of filled ampoules,
both white and brown, should be accomplished whenever possible, in a room
not being too bright. Before testing, the polarizing filter (5) should be
set to the maximum degree of polarization, i. e. nearly complete
obscuration of the visiual field, by having knob (8) moved. Should there
be any foreign matters in the ampoule held between the two filters, they
will be seen flashing up brightly and
very clearly visible in polarized light. The stand (9) is adjustable to
various heights to set the most convenient viewing height.
testing method does not overstrain the eyes of the operator, thus avoiding
any fatigue even when used for prolonged periods. The two filters and the
lens are 120 mm in diameter. This apparatus also enables ampoules and
injection vials of larger size to be tested satisfactorily.
