Description
Volumetric pipettes 7,0 ml class AS blue graduated are single-mark glass pipettes intended for precise delivery of fixed liquid volumes in analytical and routine laboratory work. They belong to accuracy class AS and are blue graduated, with a green colour code that allows rapid visual identification of the nominal volume. Calibration is to deliver (KB) and includes a defined waiting time of 5 s, supporting reproducible results in titrations, standard preparations and sample aliquoting. Offered in packs of 12 pieces from manufacturer Witeg, each pipette has a net weight of 0,024 kg. The clear blue graduation lines improve meniscus readability under typical laboratory lighting, while the robust glass body withstands repeated cleaning and handling. These volumetric pipettes are well suited to quality-control laboratories, research facilities and teaching environments that require class AS tolerances for aqueous solutions and many organic solvents. Their single-mark design minimises reading error and ensures consistent delivery performance across the pack.

Questions about Volumetric pipettes 7,0 ml class AS blue graduated
What is this article?
Volumetric pipettes 7,0 ml class AS blue graduated 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.
