Description
Dropper closure for 250-500 ml EH bottle, LDPE natural is a laboratory accessory intended for controlled dropwise dispensing from matching EH bottles. Manufactured from low-density polyethylene (LDPE) in natural colour, the closure combines flexibility with chemical resistance suitable for routine handling of aqueous and many organic laboratory liquids. Its gross weight of 0,005 kg keeps the assembly light while maintaining a secure fit on 250–500 ml EH bottles. Supplied as a single piece, the dropper closure enables precise volume delivery during sample preparation, reagent addition or titration workflows. The natural LDPE construction permits visual inspection of the contents path and supports repeated use under typical bench conditions. This component from manufacturer Kautex integrates readily into existing bottle systems used in analytical, pharmaceutical and general research laboratories where reliable drop formation is required. The design focuses on straightforward attachment and consistent flow control without additional adapters.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Dropper cap f. 250-500 ml Narrow neck bottle, LDPE natural
What is this article?
Dropper cap f. 250-500 ml Narrow neck bottle, LDPE natural is the article on this page. Luminix Health distributes Kautex 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.
