Description
Volumetric pipettes class AS with brown graduation are precision bulb pipettes designed for accurate liquid measurement in analytical and day-to-day laboratory practice. Produced from AR-GLAS®, each pipette has a nominal capacity of 20 ml and an overall length of 520 mm, supporting reliable volumetric transfer where class AS accuracy is required. The brown graduation markings give clear volume indication against a range of sample colours and lighting conditions, aiding consistent reading during titration, reagent preparation and sample aliquoting. These instruments belong to the glass liquid-handling range used in research, industrial quality-control and teaching laboratories that specify calibrated volumetric glassware. Delivered as 6 pc(s) with a combined weight of 0,295 kg, the set is well suited to busy benches and shared instrument storage. The pipettes from manufacturer Hirschmann work with common pipette aids and controllers and integrate smoothly into existing AR-GLAS® collections. Their durable glass build and defined geometry support reproducible dosing in methods that call for class AS volumetric pipettes for aqueous media and many standard laboratory solutions when handled according to good laboratory practice.
This article is part of Volumetric pipettes, in Pipettes & pipette tips.

Questions about Volumetric pipettes cl. AS, brown grad., AR-GLAS®, L 520 mm, 20 ml, 6 unit(s)
What is this article?
Volumetric pipettes cl. AS, brown grad., AR-GLAS®, L 520 mm, 20 ml, 6 unit(s) is the article on this page. Luminix Health distributes Hirschmann 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.
