Description
Sealed screw closure with dropper, DIN-18, black is a polyethylene screw closure equipped with a dropper insert and seal for controlled dispensing from DIN-18 laboratory glass bottles. The dropper opening diameter is 4 mm, supporting reproducible dropwise delivery of liquids in analytical, preparative and storage applications. Compatible with glass bottles of the FRGN, FRGA, FRGB and FRGG series, the black cap helps laboratories maintain uniform bottle–closure systems for reagents and working solutions. Supplied in a bulk pack of 1000 pieces from manufacturer Labbox, the format is intended for high-volume filling lines, kit production and central stores that require large numbers of identical sealed dropper closures. Polyethylene construction provides a secure screw fit on matching necks together with practical chemical resistance for common laboratory aqueous and solvent systems. Combining seal and dropper insert in a single component reduces handling steps and supports a closed container between dispensing events. Net weight of the pack is 3,550 kg. Well suited to production of dropper-ready reagent bottles, dispensing stations and standardised laboratory packaging workflows in research, quality control and teaching facilities.

Questions about Dropper screw cap DIN-18 with security seal, black, 1000 pcs
What is this article?
Dropper screw cap DIN-18 with security seal, black, 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.
