Beschrijving
Volumetric pipettes 15 ml, class AS are precision single-mark glass instruments for accurate delivery of fixed liquid volumes in analytical, biochemical and quality-control laboratories. Each pipette is adjusted to “Ex” (to deliver) and carries one ring mark together with brown graduations, a colour code and printed tolerance indication for rapid identification and reliable meniscus reading. Manufactured from soda-lime glass, they combine optical clarity with the mechanical robustness required for everyday wet-chemistry handling. Supplied in cartons of 25 pieces from manufacturer Marienfeld, these class AS pipettes support reproducible transfer of aqueous solutions, reagents and standards where a nominal volume of 15 ml is specified. The single-ring design minimises reading error compared with graduated pipettes and integrates smoothly with common pipette controllers and bulbs. Typical applications include titration setups, sample dilution, preparation of volumetric solutions and educational demonstrations that demand class AS accuracy. Their standardised format and clear markings make them a practical choice for research, industrial and teaching laboratories performing routine volumetric work.

Questions about Volumetric pipettes 15 ml, class AS,
What is this article?
Volumetric pipettes 15 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.
