Description
Howorka pipette bulb is a classic manual suction aid for controlled liquid handling with volumetric and graduated pipettes in the laboratory. With a 20 ml capacity, this pipetting ball supports aspiration and dispensing of aqueous solutions, buffers, and routine reagents during sample preparation, titration support work, and general wet-chemistry tasks. The compact format suits everyday bench use where simple, reliable suction without powered controllers is preferred. Offered as a single unit weighing about 0,045 kg, it is easy to store with other liquid-handling accessories. In pipette-controller and pipette-bulb workflows, the Howorka design remains a familiar choice for teaching labs, quality-control benches, and research groups that value straightforward manual operation. This Howorka pipette bulb from manufacturer ROTH SELECTION complements standard glass and plastic pipettes used across analytical and life-science laboratories. It helps operators regulate fill level by hand, reducing mouth pipetting and supporting safer liquid transfer practice. Suitable for educational settings as well as professional laboratories needing a durable, no-electronics suction bulb for 20 ml-scale work.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Pipettierball Howorka, 20 ml, 1 unit(s)
What is this article?
Pipettierball Howorka, 20 ml, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Pasteur pipettes, inside Pipettes & pipette tips, in Lab consumables.
A Pasteur pipette is an uncalibrated glass or plastic transfer pipette. It moves a drop. It does not measure. Glass ones are pulled to a tip. Plastic ones are a single piece. Neither belongs in a result that needs a stated volume.
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.
