Description
Sealed screw closure with dropper, DIN-18, white is a polyethylene screw cap fitted with an integrated dropper insert and sealing feature for controlled dispensing from laboratory glass bottles. The dropper opening measures 4 mm in diameter, supporting consistent dropwise delivery of liquids in routine analytical, preparation and storage workflows. Designed for DIN-18 neck finishes, this white closure pairs with glass bottles from the FRGN, FRGA, FRGB and FRGG series, helping laboratories standardise bottle–cap combinations across reagent lines. Supplied in a pack of 1000 pieces from manufacturer Labbox, the format suits high-throughput filling, kit assembly and stock replenishment where many identical sealed dropper closures are required. Polyethylene construction provides a practical balance of chemical resistance for common laboratory solvents and aqueous media together with reliable thread engagement on matching glassware. The combined seal and dropper insert reduces the need for separate pouring aids while maintaining a closed system between uses. Net weight of the pack is 3,550 kg. Ideal for dispensing stations, sample preparation benches and production of dropper-ready reagent bottles in research, quality-control and teaching laboratories.

Questions about Dropper screw cap DIN-18 with security seal, white, 1000 pcs
What is this article?
Dropper screw cap DIN-18 with security seal, white, 1000 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Pasteur pipettes, inside Pipettes & pipette tips, in Lab consumables.
A Pasteur pipette is an uncalibrated glass or plastic transfer pipette. It moves a drop. It does not measure. Glass ones are pulled to a tip. Plastic ones are a single piece. Neither belongs in a result that needs a stated volume.
A pipette moves a measured volume. A volumetric pipette delivers one line. A graduated pipette delivers along a scale. A Pasteur pipette is an uncalibrated transfer. A piston pipette uses a tip, and the tip has to seal on that pipette. A filter tip adds a barrier so aerosol from the sample does not reach the piston. Serological pipettes are the long graduated tubes used with a controller. The volume and the fit are the specification. Piston pipettes are treated under ISO laboratory apparatus. In-vitro work also meets ISO in vitro diagnostic systems.
