Description
PVC bulb size 9 for 224 ml pipettes is a durable suction bulb produced from flexible PVC and intended for safe macro-volume liquid handling. Tailored for 224 ml pipettes, the bulb features a bore diameter of 6 mm and a ball diameter of 84 mm that ensure a proper seal and effective generation of vacuum for aspiration and dispensing. The PVC material combines chemical resistance for many common laboratory reagents with the softness needed for comfortable one-handed control, making it a practical Peleus ball and pipetting safety aid. By replacing mouth pipetting it improves operator safety during larger-volume transfers in research, teaching and industrial laboratories. Offered as a single unit from manufacturer Witeg, the bulb fits standard pipette workflows and maintains performance through repeated use and cleaning cycles. Its ergonomic spherical shape and uniform wall thickness support consistent results in routine analytical and preparative work. Laboratories requiring a reliable accessory for 224 ml capacity pipettes will appreciate the balanced dimensions and straightforward functionality of this size 9 PVC bulb.
This article is part of Single-channel pipettes, in Liquid handling.

Questions about Suction bulb, PVC, size 9, for 224 ml pi
What is this article?
Suction bulb, PVC, size 9, for 224 ml pi is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Single-channel pipettes, inside Liquid handling, in Lab instruments.
A single-channel piston pipette delivers one volume through one tip. Fixed-volume pipettes are more accurate at their one volume. Variable pipettes cover a range and are specified at several points in it. Air displacement fails on viscous and volatile liquids.
A piston pipette delivers a set volume of liquid by air displacement or, for viscous and volatile liquids, by positive displacement. A single channel is the ordinary tool. A multichannel repeats the same volume across a row of a plate. A bottle-top dispenser meters reagent from the bottle it sits on. The accuracy is a property of the pipette and of how it is used, which is why calibration and a certificate exist. Piston-operated apparatus is treated under ISO laboratory apparatus. The volume unit sits with the BIPM and NIST.
