Description
Sealed screw closure with dropper, DIN-18, black is a polyethylene screw cap that combines a dropper insert with a sealing function for precise liquid handling on laboratory glass bottles. The dropper orifice has a diameter of 4 mm, enabling controlled dropwise addition of reagents, solvents and aqueous solutions during preparation and analysis. Intended for DIN-18 threaded necks, the black closure is compatible with glass bottles carrying the article designations FRGN, FRGA, FRGB and FRGG, supporting consistent pairing of bottles and dropper caps across laboratory inventories. Offered as a convenient pack of 20 pieces from manufacturer Labbox, this unit size is well suited to method development, small-batch filling, teaching sets and laboratories that need only limited numbers of sealed dropper closures. Polyethylene material offers dependable mechanical fit on matching glassware and practical resistance for everyday laboratory media. Integrating seal and dropper in one component simplifies dispensing while helping keep contents protected between uses. Net weight of the pack is 0,071 kg. Suitable for bench-top dispensing, sample aliquoting and preparation of dropper-ready bottles in research, QC and educational environments.

Questions about Dropper screw cap DIN-18 with security seal, black, 20 pcs
What is this article?
Dropper screw cap DIN-18 with security seal, black, 20 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.
