2-tier attachment SM is a laboratory shaker accessory featuring an attachment frame with two coated plates drilled for spring clips or test tube racks. Overall height is 332 mm with a 300 mm spacing between the tiers, giving clear vertical separation for vessels on upper and lower levels. The unit is supplied without vessel holders, allowing users to fit spring clips, test tube racks, Combifix SM attachments or the Universal tray SM as required. For more convenient loading of the lower tier outside the frame, Universal trays SM or slide-in plates with Combifix SM are recommended. Net weight is 7,7 kg and gross weight is 15,7 kg; the attachment is delivered as one piece. This 2-tier attachment from manufacturer Bühler expands the capacity of compatible shaker platforms in research, development and routine laboratory workflows.

Questions about 2-storey top frame SM
What is this article?
2-storey top frame SM is the article on this page. Luminix Health distributes Bühler for laboratory use. It sits in Stirring & mixing accessories, inside Stirring, shaking & mixing, in Instrumenten.
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.
