Description
Volumetric pipettes 4 ml, class AS are precision single-mark glass pipettes designed for accurate liquid delivery in analytical and research laboratories. Each pipette carries one ring mark and is adjusted to deliver (Ex), ensuring the nominal volume is released under standard conditions. Manufactured from soda-lime glass, the pipettes feature brown graduations together with colour coding and tolerance indication for rapid identification and verification. These class AS instruments from manufacturer Marienfeld are supplied in cartons of 30 pieces, supporting efficient stocking for routine laboratory work. The soda-lime glass construction provides reliable handling characteristics for aqueous solutions and many common reagents while remaining practical for everyday use. Suitable for volumetric analysis, preparation of standard solutions, titrations and quantitative sample work, the 4 ml capacity meets frequent needs in chemistry, biology and quality-control environments. Clear brown markings reduce reading errors, and the single-mark design simplifies operation compared with multi-graduation pipettes. Class AS accuracy supports consistent results across multiple users and instruments in teaching and professional settings alike.

Questions about Volumetric pipettes 4 ml, class AS,
What is this article?
Volumetric pipettes 4 ml, class AS, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Volumetric pipettes, inside Pipettes & pipette tips, in Consommables.
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.
