Description
Blue pipetting ball with 2 valves is a practical laboratory suction ball intended for safe aspiration and controlled release of liquids with conventional pipettes. Two dedicated pressure valves handle filling and emptying, while an automatic air outlet valve simplifies operation and reduces handling steps. The automatic valve can be detached, enabling thorough internal cleaning between uses and supporting hygienic routine work. Delivered as one piece with a net weight of 0,048 kg, the blue colour coding makes the filler easy to recognise among other bulbs kept on the same bench. This classic Peleus-type pipette aid from manufacturer Witeg forms part of the macro pipette-helper and pipette safety-ball category used wherever mouth pipetting must be avoided. Its uncomplicated design is well suited to teaching laboratories, quality-control benches and general analytical chemistry. Offered in a total of five colours, the blue variant slots neatly into colour-organised lab sets and provides dependable bulb performance for standard volumetric and measuring pipettes.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Pipette filler blue with two valves, eas
What is this article?
Pipette filler blue with two valves, eas is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
