Description
Pipette bulbs "Universal" are three-valve rubber pipette aids designed for safe aspiration and dispensing with volumetric and measuring pipettes of larger capacity. Made from red natural rubber, each bulb accommodates full and graduated pipettes up to 100 ml content with outer diameters of 5–9 mm. The three-valve configuration enables controlled filling, emptying, and venting during liquid handling in chemical, biological, pharmaceutical, and analytical laboratories. Units are individually packed in foil with a printed short description for hygiene and easy identification at the workplace. Bulk supply is 100 pieces per carton, supporting multi-user benches and higher-volume routines. These Universal pipette bulbs from manufacturer Marienfeld fall within macro pipette aids, Peleus balls, suction bulbs, and pipette safety accessories used to avoid mouth pipetting. Natural rubber delivers the elasticity and seal required for dependable manual operation across the stated pipette size range. They suit teaching laboratories, quality control, sample preparation, and general wet-chemistry work where controlled transfer of volumes up to 100 ml is needed without powered pipetting devices.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Pipette fillers ''Universal'',
What is this article?
Pipette fillers ''Universal'', is the article on this page. Luminix Health distributes Marienfeld 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.
