Description
Screw caps with dropping pipette are ready-to-use laboratory closures for controlled, dropwise dispensing from matching reagent bottles. Each assembly combines a white polypropylene screw cap with DIN thread GL 18 and a glass dropping pipette fitted with a bent ball tip plus a white rubber suction bulb. The dropping pipette length is approximately 60 mm, making the closure suitable for dropping bottles article number 3665127. These units from manufacturer Marienfeld support precise liquid handling in analytical chemistry, quality control, pharmaceutical preparation and general laboratory workflows where dropwise addition is required. The polypropylene cap provides a secure threaded seal on GL 18 bottles, while the glass pipette and rubber bulb allow reliable aspiration and release of reagents. The bent ball tip promotes consistent drop formation and reduces uncontrolled runoff. Supplied in packs of 100 pieces, the closures offer a practical consumable format for routine bench work, sample preparation and reagent storage systems that rely on dropper bottles. Their integrated design simplifies bottle setup and helps maintain clean, repeatable dispensing performance across standard laboratory applications.

Questions about Screw cap with dropping pipette,
What is this article?
Screw cap with dropping pipette, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Pipettes Pasteur, inside Pipettes & embouts de pipette, in Consommables.
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.
