Description
Pipette bulbs of soft PVC with a neck bore diameter of 6 mm and a 220 ml capacity provide substantial suction volume for demanding manual pipetting steps. The soft PVC material yields a flexible, easy-to-squeeze body that helps the user modulate fill and discharge when working with compatible pipette necks. At 220 ml, this size is oriented toward larger transfers and situations where extra bulb volume improves control and reduces the need for repeated squeezes. The 6 mm neck bore matches pipette stems designed for that opening diameter. Delivered as a pack of 2 pieces from manufacturer ROTH SELECTION, the set supports laboratories that require durable, matched bulbs for multi-user benches or teaching stations. Pack weight is 0,214 kg, remaining manageable for drawer or rack storage alongside other pipette controllers and suction cups. Soft PVC construction is suited to repeated laboratory handling under ordinary conditions. These bulbs belong to the liquid-handling segment of labware and offer a purely mechanical suction solution without electronic components.
This article is part of Pasteur pipettes, in Pipettes & pipette tips.

Questions about Pipette bulbs, soft PVC, neck bore-Ø 6 mm, 220 ml, 2 unit(s)
What is this article?
Pipette bulbs, soft PVC, neck bore-Ø 6 mm, 220 ml, 2 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.
