Description
Variable microlitre pipette 20 - 200 µl WITOPET professional is an adjustable air-displacement pipette for precise liquid handling in the microlitre range. The volume range covers 20 to 200 µl with a subdivision of 1,0 µl, supporting controlled dispensing for sample preparation, assays and routine analytical work. At 200 µl the stated accuracy is ±1,6 µl with a deviation of ±0,60 µl, in line with DIN EN ISO 8655 requirements for accuracy and precision. This model from manufacturer Witeg is made in Germany, features colour coding, an ergonomic lightweight body and optimised spring force for comfortable pipetting, together with a firmly seated stainless-steel tip ejector compatible with most common pipette tip brands. The instrument is fully autoclavable at 121 °C, carries DE-M marking under the German measurement and verification ordinance and is supplied with an individual certificate. Robust construction and competitive positioning make it suitable for quality-conscious laboratories that need reliable single-channel performance day after day. Pack size is 1 piece; net weight is 0,125 kg.
This article is part of Single-channel pipettes, in Liquid handling.

Questions about Microliter-pipette variable 20-200µl
What is this article?
Microliter-pipette variable 20-200µl is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Single-channel pipettes, inside Liquid handling, in Lab instruments.
A single-channel piston pipette delivers one volume through one tip. Fixed-volume pipettes are more accurate at their one volume. Variable pipettes cover a range and are specified at several points in it. Air displacement fails on viscous and volatile liquids.
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.
