Description
Bulb pipettes Class AS, brown graduated are glass volumetric instruments for precise transfer of larger liquid aliquots in the laboratory. Produced from AR-GLAS®, they combine a capacious bulb reservoir with a stem carrying brown graduations for lasting readability during volume setting. The nominal volume is 50 ml and the overall length is 550 mm, addressing higher-volume dispensing needs in analytical, preparative and routine workflows. Class AS accuracy is intended for quantitative applications where reproducible delivery volumes are required. Supplied by manufacturer Hirschmann as a pack of 6 pc(s), the assortment gives laboratories a ready multi-piece stock for shared use or method-specific allocation. AR-GLAS® construction supplies the durability and chemical compatibility expected of laboratory glass bulb pipettes used with aqueous solutions and many standard reagents. The brown graduation contrast aids consistent meniscus observation under typical bench lighting. Pack weight is 2,286 kg, remaining manageable for storage and issue. Appropriate for chemistry, quality-control and teaching laboratories that specify Class AS bulb pipettes at 50 ml.
This article is part of Volumetric pipettes, in Pipettes & pipette tips.

Questions about Bulb pipettes Class AS, brown graduated, AR-GLAS®, L 550 mm, vol. 50 ml
What is this article?
Bulb pipettes Class AS, brown graduated, AR-GLAS®, L 550 mm, vol. 50 ml 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.
