Description
Screw cap with dropper, DIN-18, graduated, black, for 5 ml bottles is a polypropylene (PP) closure assembly designed to convert matching laboratory glass vials into practical dropper bottles. The black DIN-18 screw cap incorporates a sealing insert, a silicone pipette bulb and a graduated glass pipette, giving controlled dropwise dispensing for routine wet-chemistry and sample-handling work. Acid- and base-resistant construction supports use with a wide range of aqueous reagents. Fitted to glass bottles from the FRGA, FRGN, FRGB and FRGG series, the assembly turns standard 5 ml vials into dedicated dropping bottles for titration, indicator addition or small-volume transfer. Supplied from manufacturer Labbox in packs of 20 pieces, the unit is suited to teaching laboratories, quality-control benches and general analytical workflows where repeatable drop delivery and chemical resistance are required. Net weight is approximately 0,150 kg per pack. The graduated glass pipette aids visual volume estimation during dispensing, while the polypropylene body and seal maintain a secure fit on DIN-18 neck finishes.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Black graduated counterdrop screw cap for 5 ml DIN-18 neck bottle, 20 pcs
What is this article?
Black graduated counterdrop screw cap for 5 ml DIN-18 neck bottle, 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.
