Description
Tipping Dispenser 25 ml NS29/32 is a complete laboratory tipping dispenser designed for controlled release of liquid reagents from a bulk reservoir. The assembly includes a 25 ml tipping mechanism with NS 29/32 ground joint, content indication and a 1 litre reservoir bottle, supplied ready for use. This configuration allows repeated delivery of a fixed 25 ml volume straight from the supply bottle, suited to analytical, preparative and everyday laboratory dispensing tasks. The NS 29/32 joint offers standard compatibility with common laboratory glass connections, while the integrated 1 litre bottle functions as the storage and feed vessel. Manufactured by Witeg, the complete unit has a net weight of 0,65 kg and a matching gross weight of 0,65 kg. It is provided as one piece and originates from Germany. Content indication supports clear identification of the liquid during routine handling. The overall design centres on straightforward operation of the reservoir and tipping action to achieve consistent release of the nominal 25 ml volume without additional intermediate vessels, serving laboratories that require a jointed dispenser system coupled to a 1 litre supply bottle.
This article is part of Bottle-top dispensers, in Liquid handling.

Questions about Automatic pipettes 25 ml ST 29/32
What is this article?
Automatic pipettes 25 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 Instruments de précision.
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.
