Volumetric pipettes 0,5 ml, Class AS are single-mark glass pipettes intended for precise delivery of fixed liquid volumes in analytical and routine laboratory work. Each pipette is manufactured from soda-lime glass in a straight form, carries one ring mark, and is adjusted to “Ex” (to deliver) in accordance with DIN EN ISO 648. Brown graduation marking, colour coding and printed tolerance information support rapid identification and correct handling during serial measurements. Class AS accuracy meets the demands of quantitative chemistry, quality control and teaching laboratories where reproducible aliquots of 0,5 ml are required. The pipettes are packed 50 pieces per carton, providing a convenient stock quantity for busy benches. These volumetric pipettes from manufacturer Marienfeld combine clear optical properties of soda-lime glass with durable brown graduation for long service life under normal laboratory conditions. Straight geometry and a single calibration mark simplify cleaning and reduce reading errors compared with graduated measuring pipettes. Suitable for aqueous solutions and many common reagents, the 0,5 ml Class AS format is a standard tool for preparing standards, performing titrations and transferring exact sample volumes in research, industrial and educational settings.
This article is part of Volumetric pipettes, in Pipettes & pipette tips.

Questions about Volumetric pipettes 0.5 ml, class AS,
What is this article?
Volumetric pipettes 0.5 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 Verbruiksartikelen.
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.
