Description
Attachment rack Combifix VKS B is a modular frame accessory featuring four horizontal and four vertical clamping strips for holding vessels in lying or upright orientations on laboratory shakers. The Combifix VKS Set B arrangement permits lying containers to be clamped securely between opposing strips, while taller vessels can also be accommodated within the same frame. Maximum spacing between the horizontal and vertical strip pairs is 60 mm, defining the working envelope for vessel diameter or height. Extra strips may be added to extend compatibility to further vessel types. The rack is designed for direct fastening to the oscillating plate of matching shaker platforms. Net weight is 4,65 kg. This attachment rack from manufacturer Bühler supports mixed-format shaking workflows, including horizontal tube or bottle incubation, tall-flask agitation and general sample mixing where both lying and standing geometries occur. Even pressure distribution along the clamping strips helps maintain vessel position throughout extended runs. The system integrates with existing VKS shaker bases, offering laboratories a flexible, reconfigurable alternative to fixed-format trays when sample containers change frequently between experiments.

Questions about Rack system Combifix VKS B
What is this article?
Rack system Combifix VKS B 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.
