Description
PVC bulb size 5 for 89 ml pipettes is a laboratory suction bulb intended for safe manual aspiration and dispensing with larger 89 ml pipettes. Produced from flexible PVC, the size 5 bulb features a bore diameter of 6 mm and a ball diameter of 62 mm, providing a secure connection to the pipette top and effective vacuum control when transferring greater liquid volumes. The soft yet durable PVC wall enables comfortable one-handed operation for filling, holding and releasing aqueous solutions and many common laboratory reagents in analytical, teaching and industrial workflows. At a net weight of 0,042 kg the bulb stays manageable on the bench while offering the robustness needed for regular use. This classic Peleus-style pipette safety ball from manufacturer Witeg supports macro-pipetting tasks wherever glass or plastic volumetric and measuring pipettes are employed without powered controllers. It is appropriate for educational laboratories, research institutes and quality-control labs that prefer simple, reusable suction devices. Supplied as a single piece, the PVC bulb size 5 integrates smoothly into existing pipette sets and storage arrangements, delivering a practical and economical solution for everyday pipetting that demands reliable manual suction and straightforward handling.
This article is part of Single-channel pipettes, in Liquid handling.

Questions about Suction bulb, PVC, size 5, for 89 ml Pip
What is this article?
Suction bulb, PVC, size 5, for 89 ml Pip 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.
