Description
DOS25 behrotest dispenser is an adjustable laboratory dispenser intended for the controlled dosing of sulphuric acid in the working range from 2,5 to 25 ml. The unit supports precise volume setting within this interval, making it suitable for routine acid addition steps in wet-chemical workflows, sample preparation and analytical procedures where sulphuric acid must be metered reproducibly. Compact single-piece supply simplifies integration into existing bench setups alongside digestion, titration or sample-conditioning equipment. Designed as part of the behrotest instrument line from manufacturer Behr, the DOS25 focuses on practical handling for sulphuric acid dosing rather than multi-reagent versatility. Laboratories performing standardised wet chemistry, environmental analysis or process control can use the adjustable 2,5–25 ml range to match common protocol volumes without changing hardware. The dispenser is offered as a complete unit ready for laboratory installation and everyday dosing tasks involving sulphuric acid.
This article is part of Bottle-top dispensers, in Liquid handling.

Questions about DOS25 behrotest metering dispenser, adjustable 2.5-25 ml
What is this article?
DOS25 behrotest metering dispenser, adjustable 2.5-25 ml is the article on this page. Luminix Health distributes Behr for laboratory use. It sits in Bottle-top dispensers, inside Liquid handling, in Lab instruments.
A bottle-top dispenser meters a reagent directly from the bottle it is mounted on, by a piston. The volume range and the chemical compatibility of the wetted parts, glass, ceramic, PTFE, are the specification. It is for the same reagent again and again, not for changing liquids every sample.
A piston pipette delivers a set volume of liquid by air displacement or, for viscous and volatile liquids, by positive displacement. A single channel is the ordinary tool. A multichannel repeats the same volume across a row of a plate. A bottle-top dispenser meters reagent from the bottle it sits on. The accuracy is a property of the pipette and of how it is used, which is why calibration and a certificate exist. Piston-operated apparatus is treated under ISO laboratory apparatus. The volume unit sits with the BIPM and NIST.
