Description
Tropf-Boy, HDPE, 25 ml, with separate closure is a compact dosing bottle for precise dropwise or splash delivery of small liquid volumes. Made from tough, chemically resistant high-density polyethylene (HDPE), it supports controlled, uniform dispensing that helps minimise waste of expensive media and avoids direct contact with the contents. The bottle is resealable with a separate screw cap. Its long, very fine dropper tip is supplied closed and is cut open before first use; the tip can be shortened so that drop size is set to the application. The stable, handy round form sits comfortably in the hand for routine work. Nominal volume is 25 ml (0,025 l) with a net weight of 0,009 kg. Tropf-Boy bottles are well suited to medicine, cosmetics, and chemical or biological laboratories for exact addition of reagents and chemicals, titrations and other analytical steps. They are also used in food and kitchen applications for accurate mixing of oils and flavours, and in furniture making for precise placement of adhesives. This dosing bottle from manufacturer Bürkle offers straightforward, hygienic liquid handling for fine laboratory and technical dosing tasks.

Questions about Drop Boy, HDPE, 25 ml, w/ separate cap
What is this article?
Drop Boy, HDPE, 25 ml, w/ separate cap is the article on this page. Luminix Health distributes Bürkle 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.
