Description
Spring strip for VKS is a laboratory accessory designed to secure the stoppers of separating funnels and other vessels during shaking operations. By holding stoppers firmly in place, the strip prevents accidental opening or leakage while samples are agitated on VKS equipment, supporting safe and reliable liquid–liquid extraction and mixing workflows. It is especially valuable when working with separating funnels, where stopper retention is critical to avoid sample loss and maintain closed-system conditions throughout the shaking cycle. The spring action provides consistent pressure without requiring constant manual attention, allowing operators to focus on process control and timing. Supplied as a single piece with a net weight of 0,75 kg and a gross weight of 1,2 kg, this component integrates into VKS configurations used across analytical chemistry, preparative work and routine laboratory practice. Manufactured by Bühler, the spring strip contributes to safer vessel handling in chemical, pharmaceutical and life-science laboratories. Its dedicated design for stopper retention helps protect both samples and equipment during vigorous or prolonged agitation on compatible shaker systems.

Questions about Spring strip for VKS
What is this article?
Spring strip for VKS is the article on this page. Luminix Health distributes Bühler for laboratory use. It sits in Stirring & mixing accessories, inside Stirring, shaking & mixing, in Lab instruments.
Stirring accessories are the bosses, the retort clamps and the spare knobs that hold an overhead stirrer over the vessel. The stand has to carry the motor's mass, not only the flask's.
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.
