Description
Screw cap with dropper PP28 for 30 ml vials is a compact laboratory closure for converting matching small bottles into dropper bottles. Constructed from polyethylene with a seal and fitted with a silicone pipette bulb, it supports controlled aspiration and dropwise delivery of liquids in everyday laboratory practice. The PP28 screw interface is compatible with glass vials FRAN and FRAA, PET vials FPET and FPTA, and HDPE vials FRIP, so those formats can be used as pipette or dropper bottles for dosing, sample preparation and reagent handling. This 30 ml variant is supplied in packs of 10 pieces from manufacturer Labbox and is listed among dropper-bottle and pipette-bottle accessories. Net weight is 0,090 kg. By pairing a sealed polyethylene head with a soft silicone suction element, the cap offers a practical route to droplet dispensing on smaller vial volumes without redesigning the bottle itself, keeping workflows tidy at the bench.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Counter drop screw cap for 30 ml PP28 neck bottle, silicone teat, 10 pcs
What is this article?
Counter drop screw cap for 30 ml PP28 neck bottle, silicone teat, 10 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.
