Description
Dosing pump with screw cap is a hand-operated liquid-handling accessory made from HDPE for controlled dispensing from laboratory containers. It is configured for a DIN 50 thread, has a length of 175 mm and delivers approximately 30 ml per stroke, supporting repeatable transfer of aqueous media, buffers and process liquids from canisters or bottles. The robust polymer construction suits everyday bench and store-room use where chemical resistance and simple manual operation are preferred over powered pumps. Supplied as 1 pc with a weight of 0,070 kg, the unit is easy to mount, clean and keep as a dedicated dispenser on a single container. This dosing pump from manufacturer ROTH SELECTION belongs to the canister and barrel pump family used in liquid-handling workflows across research, production support and general laboratory logistics. Typical applications include aliquot preparation, reagent top-up and measured emptying of stock solutions without pouring. The screw-cap interface helps secure the pump on compatible vessels during use and storage, reducing spills and simplifying routine dispensing tasks.
This article is part of Plastic bottles (narrow & wide mouth), in Bottles & containers.

Questions about Dosing pump with screw cap, HDPE, DIN 50, L 175 mm, 30 ml/stroke, 1 unit(s)
What is this article?
Dosing pump with screw cap, HDPE, DIN 50, L 175 mm, 30 ml/stroke, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Plastic bottles (narrow & wide mouth), inside Bottles & containers, in Labware.
A plastic bottle is polyethylene, polypropylene or a fluoropolymer, narrow-mouth for pouring or wide-mouth for powders. It is the choice when the bottle must not shatter, and it is the wrong choice for solvents that swell the plastic.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
