Description
Tipping dispenser 4 ml NS29/32 is a complete laboratory tipping dispenser for controlled delivery of fixed liquid aliquots. The unit provides a dispensing volume of 4 ml and is equipped with a standard ground joint NS 29/32 for secure connection to compatible glassware. It is supplied together with a 1 litre reservoir bottle, enabling convenient reagent storage and repeated tipping cycles directly from the bottle. This tipping dispenser from manufacturer Witeg is offered as a ready-to-use assembly for routine laboratory liquid handling. Operation is based on tilting the reservoir to fill the measuring chamber and then tipping to release the measured 4 ml volume. The complete unit has a net weight of 0,692 kg and a gross weight of 0,692 kg and is supplied as one piece. Originating from Germany (Baden-Württemberg), the dispenser is intended for general laboratory workflows that require simple, repeatable fixed-volume dispensing via a conical NS 29/32 joint. The combination of reservoir bottle, defined 4 ml content and standard joint makes it a practical choice for everyday reagent handling at the bench.

Questions about Automatic pipettes, with 1 l reservoir b
What is this article?
Automatic pipettes, with 1 l reservoir b 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.
