Beschrijving
Screw caps with dropping pipette are laboratory closures engineered for controlled dropwise dispensing from matching dropper bottles. Each assembly features a white polypropylene screw cap with DIN thread GL 18 together with a glass dropping pipette that has a bent ball tip and a white rubber suction bulb. The dropping pipette length is approximately 77 mm and is compatible with dropping bottles article number 3665103. These closures from manufacturer Marienfeld are intended for analytical chemistry, quality-control, pharmaceutical and general laboratory workflows where precise liquid addition is needed. The polypropylene cap forms a secure seal on GL 18 bottles, while the glass pipette and rubber bulb allow reliable uptake and release of reagents. The bent ball tip assists uniform drop formation and cleaner application. Supplied in packs of 100 pieces, they provide a convenient consumable format for routine bench work, sample preparation and reagent storage based on dropper bottles. The integrated design simplifies setup of dispensing bottles and supports repeatable performance in everyday laboratory handling of solutions and reagents.

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 Pasteurpipetten, inside Pipetten & pipetpunten, in Verbruiksartikelen.
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.
