Description
Rubber bulbs for dropping pipettes are compact suction caps intended for controlled dropwise liquid transfer. Each bulb offers a suction volume of approximately 0,8 ml and is supplied in a distinctive red colour for easy visual identification on the bench. Packed in sets of 100 pieces, they are well suited to routine laboratory work with dropping pipettes in chemistry, biology, and educational settings. The soft rubber construction allows gentle aspiration and release, supporting accurate drop formation without mechanical complexity. These bulbs serve as straightforward pipetting aids where small volumes must be handled repeatedly and reliably. Manufactured by Marienfeld, they integrate smoothly into standard glassware workflows and help maintain clean, efficient liquid handling. Their modest capacity matches typical dropping-pipette applications, from reagent addition to sample spotting. Ideal for teaching laboratories, quality-control benches, and general analytical preparation, the red bulbs provide a practical, ready-to-use accessory that keeps everyday pipetting simple, visible, and consistent across multiple users and stations.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Rubber teats for dropping pipettes,
What is this article?
Rubber teats for dropping pipettes, 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.
