Description
Measuring pipettes 25:0,1 ml class B are graduated glass volumetric instruments intended for accurate liquid transfer and measurement in routine laboratory work. These class B pipettes deliver a nominal capacity of 25 ml with 0,1 ml graduation intervals and conform to ISO 835. Constructed for total delivery (Vollablauf), they empty completely under gravity for reliable volumetric results. A white colour code enables rapid visual size identification on the bench. Suitable for general analytical chemistry, sample preparation, titration support and educational use, the pipettes from manufacturer Witeg offer consistent class B performance across research, quality-control and teaching environments. Each unit has a net weight of 0,034 kg and is supplied in packs of 12 pieces. The clear glass body and permanent graduations support repeated handling of aqueous solutions and many common laboratory reagents while remaining within the stated accuracy class. These measuring pipettes form a practical addition to any standard glassware inventory requiring graduated volumetric tools for everyday liquid handling tasks.

Questions about Graduated pipettes, measuring, class B,
What is this article?
Graduated pipettes, measuring, class B, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Graduated pipettes, inside Pipettes & pipette tips, in Lab consumables.
A graduated pipette delivers a chosen volume along a scale, to contain or to deliver as marked. Class A and class B differ in tolerance. A serological pipette is a different, usually plastic, article. Reading the meniscus and delivering correctly, blow-out or not, is printed on the pipette.
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.
