Description
Screw cap with dropper, DIN-18, graduated, for 50 ml bottles is a polypropylene screw closure with seal, silicone pipette bulb and glass pipette for turning compatible glass vials into dropper bottles. The graduated glass pipette supports measured, dropwise delivery, and the assembly is acid- and base-resistant for typical laboratory reagents. Made for the DIN-18 neck on 50 ml bottles, it enables glass vials with article numbers FRGA, FRGN, FRGB and FRGG to be used as dropper bottles in standard pipette-bottle applications. The polypropylene (PP) cap with sealing element, silicone suction bulb and glass pipette forms one integrated dropper unit ready for bench use. Packs of 20 pieces have a net weight of 0,355 kg, convenient for laboratories that equip multiple small bottles for controlled transfer. From manufacturer Labbox, this graduated DIN-18 dropper cap complements the listed vial ranges and suits analytical, teaching and general wet-lab settings where a sealed PP screw finish plus glass dropper pipette are required without changing the underlying bottle platform.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Graduated counterdrop screw cap for 50 ml DIN-18 neck bottle, 20 pcs
What is this article?
Graduated counterdrop screw cap for 50 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.
