Description
Screw cap with dropper DIN-18, black, is a polypropylene closure designed to convert matching 50 ml glass vials into practical dropper bottles for laboratory dispensing. The assembly combines a sealed polypropylene screw cap with a silicone pipette bulb and a glass pipette, giving controlled dropwise delivery of reagents, solvents and sample solutions. Threaded to the DIN-18 standard and finished in black, the cap seats securely on compatible glass vials referenced under article series FRGA, FRGN, FRGB and FRGG, turning standard bottles into dedicated dropper units without additional adapters. Supplied as a pack of 20 pieces from manufacturer Labbox, the set is suited to routine wet-chemistry workflows, sample aliquoting and preparation of drop-dispensed media where a reliable seal and inert contact materials are required. Net weight of the pack is 0,355 kg. The polypropylene body, silicone bulb and glass pipette together provide a straightforward, reusable dropper interface for analytical and general laboratory use.

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