Description
Screw cap with dropper DIN-18 for 20 ml vials is a polypropylene closure complete with seal, silicone pipette bulb and glass pipette, converting matching glass vials into practical dropping bottles. Intended for laboratory and medical workflows that need controlled, dropwise dispensing of reagents and solutions, the assembly supports clean handling at the bench. The DIN-18 thread provides a secure fit on compatible 20 ml glass vials from the FRGA, FRGN, FRGB and FRGG series, so existing stock can be used as dropper bottles without extra adapters. Supplied as a pack of 20 pieces from manufacturer Labbox, the set offers a ready-to-use dropper solution with integrated pipette components. Polypropylene construction suits routine chemical contact, while the silicone bulb and glass pipette enable consistent drop formation for sample preparation, titration support and general liquid transfer. Categories include dropping bottles and pipette bottles, reflecting everyday use in research, quality control and teaching laboratories where reliable dropwise delivery is required.

Questions about Counter drop screw cap for 20 ml DIN-18 neck bottle, 20 pcs
What is this article?
Counter drop screw cap for 20 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.
