Description
Tipping Dispenser 20 ml NS29/32 is a complete laboratory tipping dispenser for controlled liquid delivery from a reservoir bottle. It comprises a 20 ml tipping unit with NS 29/32 ground joint, content indication and a 1 litre reservoir bottle supplied as a ready assembly. The arrangement enables repeated dispensing of a defined 20 ml volume directly from the bulk supply, supporting analytical and general laboratory procedures that require consistent volumetric transfer. The NS 29/32 joint ensures compatibility with standard glassware interfaces, while the 1 litre bottle acts as both storage and feed vessel. From manufacturer Witeg, this complete tipping dispenser has a net weight of 0,66 kg and an identical gross weight of 0,66 kg. It is delivered as one piece and originates from Germany. Content indication on the assembly aids identification of the contained liquid during routine use. The design emphasises simple handling of the reservoir and tipping action for reliable release of the nominal 20 ml volume without separate intermediate containers, making it practical for laboratories needing a jointed dispenser linked to a 1 litre supply bottle.
This article is part of Bottle-top dispensers, in Liquid handling.

Questions about Automatic pipettes 20 ml ST 29/32
What is this article?
Automatic pipettes 20 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.
