Beschreibung
Screw cap with dropper, DIN-18, graduated, black, for 20 ml bottles is a polypropylene closure that equips matching glass vials for use as dropping bottles. The unit integrates a sealing screw cap, a silicone pipette bulb and a glass pipette to provide controlled dropwise dispensing in laboratory routines. Graduations on the pipette allow approximate volume assessment while transferring reagents or solutions. Acid- and base-resistant construction supports handling of many aqueous media common in analytical, preparative and educational settings. Compatible glass bottle ranges FRGA, FRGN, FRGB and FRGG can be converted into dropper bottles without changing the underlying vessel design. Available as a pack of 20 pieces from manufacturer Labbox, the black DIN-18 thread fits the corresponding neck finish on 20 ml bottles. Net weight of the pack is 0,325 kg. This accessory is suited to sample handling, reagent dosing and teaching applications that need straightforward, repeatable drop delivery from standard small glassware.

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