Description
Screw cap with dropper DIN-18 for 5 ml vials is a polypropylene closure assembly that converts matching glass vials into practical dropper bottles for laboratory dispensing. The cap combines a polypropylene screw closure with sealing, a silicone pipette bulb, and a glass pipette, enabling controlled dropwise delivery of liquids from small-volume containers. It is intended for glass vials with article designations FRGA, FRGN, FRGB, and FRGG, turning those bottles into dropper-style vessels for reagents, standards, or sample aliquots. Supplied as a pack of 20 pc(s) from manufacturer Labbox, the DIN-18 format suits 5 ml vial necks commonly used in analytical, pharmaceutical, and general laboratory work. Material of construction is polypropylene (PP) for the screw cap body, paired with the silicone bulb and glass pipette for chemical handling and visual control of drop formation. Net weight is 0,150 kg. Ideal where repeatable manual dosing from compact vials is required without separate external droppers.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Counter drop screw cap for 5 ml DIN-18 neck bottle, 20 pcs
What is this article?
Counter drop screw cap for 5 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.
