Description
Tipping Dispenser 3 ml NS 29/32 is a complete laboratory tipping dispenser configured for accurate manual release of fixed 3 ml liquid portions in analytical, preparative and teaching laboratories. The system includes a 1 litre reservoir bottle fitted with a core ground joint NS 29/32 and a tipping mechanism calibrated to deliver 3 ml per tip. This arrangement supports titration, controlled reagent addition, sample dilution and repetitive volumetric transfers where a slightly larger fixed aliquot is advantageous. Supplied as a ready-to-use assembly from manufacturer Witeg, the dispenser integrates reservoir and dispensing head into a compact glass unit that connects directly to standard laboratory ground-joint apparatus. Net weight of 0,712 kg ensures convenient handling and stable bench placement during successive operations. The substantial reservoir volume reduces the need for frequent refills when running extended series of measurements, while the fixed 3 ml delivery promotes consistency across classical wet-chemistry protocols. Suitable for chemistry, biochemistry and quality-control settings, the design emphasises simplicity, chemical resistance and reliable manual performance without electronic components.
This article is part of Bottle-top dispensers, in Liquid handling.

Questions about Automatic pipette 3 ml ST 29/32
What is this article?
Automatic pipette 3 ml ST 29/32 is the article on this page. Luminix Health distributes Witeg 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.
