Volumetric pipettes 50 ml, class AS are single-ring-mark glass pipettes calibrated to deliver (Ex) in accordance with DIN EN ISO 648. Made from soda-lime glass and featuring brown graduations together with colour coding and tolerance indication, these class AS instruments provide reliable volumetric accuracy for quantitative liquid transfer in analytical and routine laboratory work. The nominal volume of 50 ml supports precise dispensing of aqueous solutions and reagents where high accuracy is required. Each pipette carries a single ring mark for clear meniscus reading and is finished to the dimensional and tolerance requirements of the relevant standard. Supplied by manufacturer Marienfeld, the pipettes are packed ten pieces per carton, ready for immediate use in quality-control, research or teaching laboratories. The soda-lime glass construction offers good chemical resistance for general aqueous applications while the brown graduation ensures lasting legibility. Colour coding facilitates rapid identification of the 50 ml size among other volumetric glassware. These volumetric pipettes form a practical choice for laboratories seeking standardised class AS glassware that meets DIN EN ISO 648 specifications for delivery calibration.

Questions about Volumetric pipettes 50 ml, class AS,
What is this article?
Volumetric pipettes 50 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.
