Each of these indicator
sprayers provides a fine, uniform spray ideally suited for development of
chromatography patterns. Spray pattern is adjustable by varying the coverage
of the vent hole with thumb. They are also suitable for uses in
electrophoresis, benezidine tests for blood, and many other tests. The
sprayers are made of borosilicate glass and consist of an atomizer top attached
with a screw top and O-ring to the reservoir flask. The screw top delivers a
positive seal between spray head and reservoir, eliminating the possibility of
“blow back”. Unit is autoclavable for sterilizing because the nut and O-ring
are easy to remove. Operation of the unit is by low pressure air (5 lbs).
