These indicator sprayers use low pressure air (5 lbs.) to provide a fine, uniform spray that is ideally adjusted for development of chromatography patterns

The sprayers are made of borosilicate glass and consist of atomizer tops attached with a screw top and O-ring to reservoir flasks. The screw top delivers a positive seal between sprayer head and reservoir, eliminating the possibility of “blow back.” The easy to remove nut and O-ring allows the unit to be autoclavable.

Spray pattern is adjustable by varying the coverage of vent hole with thumb. Suitable for uses in electrophoresis, benezidine tests for blood, and many other tests.
