Description
Volumetric pipettes 4,0 ml class AS blue graduated are single-mark glass pipettes intended for accurate volumetric delivery in laboratory applications. These class AS instruments carry one calibration mark, KB calibration and a waiting time of 5 s, ensuring reliable transfer of liquids under controlled conditions. Blue graduation markings improve visibility of the meniscus while the red colour code allows rapid identification of the 4,0 ml nominal volume. Offered in packs of 12 pieces from manufacturer Witeg, each pipette has a net weight of 0,024 kg and suits routine analytical tasks, sample preparation and reagent dispensing. The combination of class AS accuracy, clear blue graduation and durable construction supports consistent performance in chemical, pharmaceutical and research environments. Proper technique together with the prescribed waiting time helps achieve reproducible results. These blue-graduated volumetric pipettes fit seamlessly into standard glassware sets for everyday precision liquid handling.

Questions about Volumetric pipettes 4,0 ml class AS blue graduated
What is this article?
Volumetric pipettes 4,0 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.
