Description
KPG-Stirrer with movable blades, DURAN® is a laboratory stirring accessory sized for 1000 ml flasks, with an overall length of 400 mm and a blade circle of 90 mm. Movable blades help the stirrer pass through a narrow flask neck and then open for effective agitation of reaction mixtures in round-bottom and related glass vessels. The DURAN® designation identifies the glass quality used for this KPG-style component in everyday chemical laboratory work. Suitable as an accessory for agitators, it supports controlled mixing in synthesis, preparative chemistry, and general laboratory stirring setups where a matched stirrer geometry is required. This model from manufacturer Lenz is offered as a single piece with a weight of 0,151 kg, making it straightforward to integrate into existing KPG ground-joint assemblies and drive arrangements. Use it wherever a 1000 ml flask volume, 400 mm length, and 90 mm blade circle are specified for reproducible mechanical stirring. The design fits standard labware workflows in research, teaching, and process-development environments that rely on glass stirrers with adjustable blades for homogeneous mixing without unnecessary complexity.
This article is part of Overhead stirrers, in Stirring, shaking & mixing.

Questions about KPG-Stirrer with movable blades, DURAN®, flask 1000 ml, L 400 mm, circle 90 mm
What is this article?
KPG-Stirrer with movable blades, DURAN®, flask 1000 ml, L 400 mm, circle 90 mm is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Overhead stirrers, inside Stirring, shaking & mixing, in Lab instruments.
An overhead stirrer drives a shaft from above, for volumes and viscosities a magnetic bar cannot move. Torque and speed range are the ratings. The chuck and the stand are part of using it. A high-speed disperser is a different head.
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.
