Description
Yellow pipetting ball with 2 valves is a compact laboratory suction ball for controlled aspiration and dispensing with standard pipettes. It combines two pressure valves for drawing up and emptying liquid with an automatic air outlet valve, giving simple, reliable one-handed handling at the bench. The automatic valve is removable, which allows effective internal cleaning and helps keep the bulb ready for repeated daily use. Supplied as a single piece with a net weight of 0,049 kg, the yellow colour supports quick visual identification in multi-user or teaching environments where several fillers are kept side by side. This Peleus-style pipette aid from manufacturer Witeg belongs to the established range of macro pipette helpers and pipette safety balls that replace mouth pipetting. The straightforward valve layout suits volumetric work, routine wet chemistry and educational laboratories that still prefer classic rubber-bulb fillers. Available overall in five colours, the yellow version integrates easily into colour-coded workstation systems while delivering consistent suction performance for everyday glass and plastic pipettes.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Pipette filler yellow with two valves, e
What is this article?
Pipette filler yellow with two valves, e 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.
