Description
Rubber bulbs for Pasteur pipettes are olive-shaped suction aids made from natural rubber in a natural transparent finish. Each bulb delivers a suction volume of 1,8 ± 0,3 ml, with a length of 36,4 ± 1,0 mm, an inner diameter at the opening of 5,8 ± 0,4 mm, and a wall thickness of 1,6 ± 0,3 mm, ensuring a secure fit on standard Pasteur pipettes. The soft, resilient natural rubber supports controlled aspiration and dispensing for routine liquid transfer in microbiology, chemistry, and general laboratory practice. Packed in units of 100 pieces, with bulk availability of 6,000 pieces, these bulbs suit high-throughput teaching and research environments. From manufacturer Marienfeld, they provide a reliable, economical pipetting accessory that pairs cleanly with glass Pasteur pipettes. Dimensions and tolerances support consistent handling, while the olive profile improves grip and seating. Use them wherever gentle suction control is needed without complex mechanical aids, keeping workflows simple and reproducible across daily sample preparation tasks.

Questions about Rubber teats for Pasteur pipettes,
What is this article?
Rubber teats for Pasteur pipettes, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Pipettes Pasteur, inside Pipettes & embouts de pipette, in Consommables.
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.
