Description
Spray insert GL 18 is a replacement or complementary spray insert for laboratory bottles fitted with a GL 18 thread. It is specified for use with 50 ml and 100 ml bottles, enabling directed dispensing when paired with matching screw-neck vessels. The GL 18 thread ensures correct seating on compatible narrow-neck laboratory bottles used for wash, rinse or reagent application tasks. Net and gross weight are each only 0,006 kg, reflecting a compact insert intended as a functional accessory rather than a full bottle assembly. This spray insert from manufacturer Witeg supports laboratories that maintain modular bottle systems and need spare or dedicated inserts for small-volume PE or glass bottles with GL 18 closures. Typical contexts include sample preparation, rinsing of small glassware and controlled delivery of wash liquids from 50 ml or 100 ml containers. Selecting the correct GL 18 insert helps restore or standardise spray performance without replacing the entire bottle. The component fits workflows built around threaded laboratory bottles in chemistry, biology and teaching labs where interchangeable inserts simplify stock and maintenance.

Questions about Spraying insert GL18
What is this article?
Spraying insert GL18 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Bottle accessories (pouring rings, dispensers, caps), inside Bottles & containers, in Labware.
Bottle accessories are the pieces on the neck: a pouring ring, a dispenser seat, a cap liner, a tamper ring. They decide how the bottle delivers and whether the closure still matches after the original cap is gone.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
