Description
Pipette bulbs, silicone are laboratory accessories for manual liquid handling with standard pipettes. Each bulb is made of silicone and features an opening diameter of 5 mm, a length of 40 mm and a capacity of 1 ml. The flexible silicone body allows controlled aspiration and dispensing when fitted to the upper end of a pipette. These pipette bulbs are supplied in a pack of 10 pc(s) with a total weight of 0,020 kg, making them practical for bench stock and routine replacement. Available from manufacturer ROTH SELECTION, the set matches the stated opening, length and volume specifications for straightforward selection. The 5 mm openings define the interface with the pipette stem, while the 40 mm length keeps the accessory compact in the hand. With a nominal capacity of 1 ml, the bulbs suit small-volume transfer, sample preparation and general volumetric work. Packs of ten pieces support consistent availability across multiple workstations. Silicone construction delivers the flexibility required for repeated compression during everyday pipetting. Dimensions, capacity and pack quantity are clearly defined so laboratories can pair the bulbs with matching pipettes without guesswork.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Pipette bulbs, silicone, Ø of openings 5 mm, L 40 mm, 1 ml, 10 unit(s)
What is this article?
Pipette bulbs, silicone, Ø of openings 5 mm, L 40 mm, 1 ml, 10 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.
