Description
Pipette bulbs made of soft PVC with a neck bore diameter of 6 mm and a 30 ml capacity are practical suction aids for everyday liquid handling in the laboratory. The flexible bulb design supports controlled aspiration and release when working with standard glass or plastic pipettes that match the 6 mm neck opening. Soft PVC gives a responsive feel under the hand, helping operators regulate fill and empty cycles during routine transfers, dilutions and sample preparation. This 30 ml size suits smaller working volumes and compact bench setups where a light, easy-to-squeeze bulb is preferred. Offered as a pack of 5 pieces from manufacturer ROTH SELECTION, the set is convenient for teaching laboratories, quality-control stations and multi-user research environments that need several identical bulbs on hand. The pack weight is 0,110 kg, so the units store neatly with other pipette controllers and suction accessories. These bulbs belong to the liquid-handling category of labware and provide a straightforward, reusable option for manual pipetting without electronic controllers.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Pipette bulbs, soft PVC, neck bore-Ø 6 mm, 30 ml, 5 unit(s)
What is this article?
Pipette bulbs, soft PVC, neck bore-Ø 6 mm, 30 ml, 5 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.
