Description
Screw cap with dropper, DIN-18, graduated, for 30 ml bottles is a polypropylene screw closure fitted with a seal, silicone pipette bulb and glass pipette so matching glass vials can serve as dropper bottles. Graduation on the pipette aids controlled dispensing, and the construction is acid- and base-resistant for everyday laboratory reagents. The DIN-18 thread is intended for 30 ml bottles and allows glass vials with article numbers FRGA, FRGN, FRGB and FRGG to function as dropper bottles in pipette-bottle workflows. Material of the cap is polypropylene (PP), combined with a sealing element, silicone suction bulb and glass pipette as a complete dropper assembly. Supplied as 20 pieces per pack with a net weight of 0,350 kg, the set is practical for stocking benches that regularly convert small glass bottles for dropwise application. Manufacturer Labbox provides this graduated screw-cap dropper as a dedicated accessory for the listed vial series, supporting analytical, educational and general lab use where a sealed PP finish and glass dropper pipette are needed together without altering the base bottle system.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Graduated counterdrop screw cap for 30 ml DIN-18 neck bottle, 20 pcs
What is this article?
Graduated counterdrop screw cap for 30 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.
