Description
Volumetric pipettes 4,5 ml class AS blue are single-mark glass instruments engineered for precise delivery of a fixed 4,5 ml volume under class AS accuracy conditions. They incorporate a 5 s waiting time, are calibrated for delivery (KB) and feature a blue DIFFICO finish for clear visual differentiation. Belonging to the volumetric and glass pipette product groups, these pipettes enable reliable liquid transfer in analytical chemistry, quality control and research workflows. The single graduation mark defines the exact delivery volume once the prescribed waiting period is observed. Supplied in packs of 12 pc(s) from manufacturer Witeg, the pipettes originate from Germany (Baden-Württemberg). Their class AS tolerance supports quantitative laboratory procedures that require high volumetric fidelity. The blue DIFFICO surface improves handling recognition and contributes to durable everyday performance. These tools are appropriate for standardised sample preparation, titration sequences and any protocol where a calibrated 4,5 ml aliquot must be dispensed consistently and without intermediate volume selection.
This article is part of Volumetric pipettes, in Pipettes & pipette tips.

Questions about Volumetric pipettes 4,5 ml class AS blue
What is this article?
Volumetric pipettes 4,5 ml class AS blue is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Volumetric pipettes, inside Pipettes & pipette tips, in Lab consumables.
A volumetric pipette has a single mark and a bulb, and it delivers one volume with a tighter tolerance than a graduated pipette. It is for preparing standards. It is not for reagents that attack glass, and it is not a blow-out pipette unless it is marked as one.
A pipette moves a measured volume. A volumetric pipette delivers one line. A graduated pipette delivers along a scale. A Pasteur pipette is an uncalibrated transfer. A piston pipette uses a tip, and the tip has to seal on that pipette. A filter tip adds a barrier so aerosol from the sample does not reach the piston. Serological pipettes are the long graduated tubes used with a controller. The volume and the fit are the specification. Piston pipettes are treated under ISO laboratory apparatus. In-vitro work also meets ISO in vitro diagnostic systems.
