Description
ROTILABO® stirrer blades with smooth ends are laboratory stirring blades dimensioned 65 × 25 × 3,2 mm and intended for use with 250 ml round-bottom flasks. The smooth-ended blade geometry is designed for gentle yet effective agitation inside standard round-bottom glassware commonly employed in synthesis and sample work-up. These blades form part of the accessories range for laboratory agitators and stirrers. Each pack contains 5 pieces and has a total weight of 0,041 kg, making the set convenient for stocking multiple identical blades or for equipping several parallel setups. The 65 × 25 × 3,2 mm format matches the working volume and neck geometry of 250 ml round-bottom flasks, supporting controlled mixing without oversized blade sweep. Smooth ends help reduce catching on flask walls or joints during rotation and insertion. Offered under the ROTILABO® line from manufacturer ROTH SELECTION, these stirrer blades suit routine laboratory agitation tasks in teaching, research and quality-control environments. They are selected when a defined blade size for 250 ml round-bottom flasks is required as a consumable or spare accessory for existing stirrer shafts and drives, keeping mixing configurations consistent across experiments.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about ROTILABO®-stirrer blades w. smooth ends, 65x25x3.2, f. 250 ml round bottom flask
What is this article?
ROTILABO®-stirrer blades w. smooth ends, 65x25x3.2, f. 250 ml round bottom flask is the article on this page. Luminix Health distributes Carl Roth 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.
