Description
Screw cap with dropper, DIN-18, graduated, black, for 15 ml bottles is a polypropylene closure intended to turn compatible small glass vials into convenient dropping bottles. It comprises a sealing screw cap, a silicone pipette bulb and a glass pipette, enabling controlled dropwise delivery of liquids in everyday laboratory practice. Graduations on the pipette assist approximate volume reading during transfer. Acid- and base-resistant materials make the assembly suitable for many aqueous reagents and solutions used in analytical, preparative and teaching laboratories. Glass bottles from the FRGA, FRGN, FRGB and FRGG series can be fitted with this closure and used as dropper bottles without altering the vessel format. Supplied in packs of 20 pieces from manufacturer Labbox, the black DIN-18 thread matches the neck finish of corresponding 15 ml bottles. Net weight of the pack is 0,250 kg. The product supports reagent dosing, sample handling and instructional workflows that require simple, repeatable drop dispensing from compact glassware.

Questions about Black graduated counterdrop screw cap for 15 ml DIN-18 neck bottle, 20 pcs
What is this article?
Black graduated counterdrop screw cap for 15 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.
