Description
Pipette bulbs, silicone serve as manual liquid-handling aids for laboratory pipettes. Manufactured from silicone, each bulb has an opening diameter of 8 mm, a length of 56 mm and a capacity of 5 ml. The soft silicone construction enables controlled suction and release once the bulb is placed on the pipette. These pipette bulbs are packed as 5 pc(s) with a combined weight of 0,050 kg, convenient for stocking at the workbench. The range is available from manufacturer ROTH SELECTION and is described by the stated opening, length and volume values. An 8 mm opening diameter accommodates pipette stems of matching outer size, while the 56 mm length keeps the bulb manageable during use. The 5 ml capacity supports medium small-volume transfers, aliquoting and general volumetric tasks. Five-unit packs allow orderly replacement of worn or contaminated bulbs. Silicone provides the flexibility required for repeated compression in routine laboratory practice. All key dimensions, capacity and pack quantity are given so users can select the correct accessory alongside their pipettes.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Pipette bulbs, silicone, Ø of openings 8 mm, L 56 mm, 5 ml, 5 unit(s)
What is this article?
Pipette bulbs, silicone, Ø of openings 8 mm, L 56 mm, 5 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.
