Description
Soaking cap for shaft 8 mm and puncture electrodes is a compact laboratory accessory designed to protect and condition electrode shafts during storage and between measurements. Intended for use with puncture electrodes and related sensor assemblies that employ an 8 mm shaft, it helps keep the sensing tip in a controlled wet environment so that response characteristics remain stable in routine analytical work. The component belongs to the electrode and sensor accessory range used alongside pH electrodes, conductivity sensors and oxygen sensors in laboratory and process setups. Supplied as a single piece with a net and gross weight of 0,01 kg, it is a lightweight part that fits easily into electrode kits and maintenance trays. This soaking cap from manufacturer Mettler-Toledo OnLine supports everyday electrode care workflows where puncture-style sensors must remain ready for use without drying out at the membrane or junction. Laboratories handling food, environmental or industrial samples that rely on robust puncture electrodes can integrate the cap into standard storage and rinsing routines. Its simple form factor makes it straightforward to place on compatible 8 mm shafts after cleaning or calibration, contributing to consistent sensor handling and longer practical readiness of the measurement chain.

Questions about Wetting caps 8mm
What is this article?
Wetting caps 8mm is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Lab instruments.
A shaft, a propeller or an impeller is the wetted end of an overhead stirrer. The diameter and the pitch decide whether the liquid turns over. The material, stainless steel or PTFE, decides what the liquid may be. The chuck size has to match the stirrer.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
