Description
Bottle-top MINISPENSOR 50+100 µl is a fixed-volume precision dispenser for accurate small-volume dosing directly from a reservoir bottle. This yellow high-quality instrument, manufactured in Germany by Witeg, offers two preset volumes of 50 µl and 100 µl with accuracy of ±1,5 µl and deviation of ±0,3 µl, meeting error limits better than ISO 8655 requirements. As a universal direct-displacement system it resists most chemicals and is well suited to crystallising liquids, while avoiding the need for pipette tips and thus providing an economical alternative to microlitre pipettes. Volume selection is simple, operation is one-handed with automatic refill, and the cannula rotates 180° for fully drip-free dispensing. The unit is easy to clean and fully autoclavable at 121 °C, and carries DE-M marking in accordance with the German weights and measures ordinance. Scope of supply includes the MINISPENSOR, GL28/GL32 thread adapter, 100 ml reservoir bottle, operating instructions and an individual certificate.
This article belongs on Bottle-top dispensers, in Liquid handling.

Questions about Bottletop-Minispensor 50+100µl
What is this article?
Bottletop-Minispensor 50+100µl 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.
