Description

Closure for bottles with 18 mm thread, DIN18 or GL18.
The insert vertical dropper is made of polyethylene plastic (PE) in natural colour.
The diameter of the outlet hole is 0.7 mm. The ease of dripping the fluid will depend on its density and the size of the hole in the plug. To choose the best dropper, we recommend testing the density of the fluid to be contained in the container.
Its use is not recommended when work processes require a high degree of precision in the quantity of liquid to be poured, for these cases there are more suitable instruments such as the pipette or the volumetric burette.
