Description
Howorka pipette bulb is a manual suction device for safe, controlled pipetting of larger liquid volumes in laboratory liquid-handling routines. Rated at 50 ml, this pipetting ball is suited to volumetric work, reagent transfer, and preparation steps that exceed small-bulb capacities while still relying on simple hand operation. It supports aspiration and release with standard pipettes used in analytical chemistry, teaching laboratories, and routine quality-control benches. Supplied as one piece with a pack weight of approximately 0,105 kg, the bulb is convenient to keep at the workstation alongside other pipette accessories. Within the family of pipette controllers, bulbs, and suction cups, the Howorka format remains a practical option when electronic controllers are unnecessary. This 50 ml Howorka pipette bulb from manufacturer ROTH SELECTION offers a straightforward alternative for operators who prefer tactile control of fill and discharge. It helps avoid mouth pipetting and supports consistent technique during repeated transfers of aqueous solutions and common laboratory liquids. Appropriate for education, research, and industrial labs that need a larger-capacity manual pipette bulb for everyday wet-lab tasks.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Pipettierball Howorka, 50 ml, 1 unit(s)
What is this article?
Pipettierball Howorka, 50 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.
