Metrohm 719S Titrino with 20ml burette and 728 Stirrer

Magnetic stirrer MICROSTIRRER Velp The Microstirrer magnetic stirrer is a small, simple and effectiv (more)e instrument, specially designed for microtitering. It has a high resistance to chemical agents, thanks to the metal structure and the epoxy paint. It does not overheat, even after several days of continuous use the stirrer remains cold, a characteristic that makes it particularly valuable in chemistry, microbiology and biochemistry. - The control panel is protected against liquid spills - Durable steel casing with epoxy coating - Accepts bottles up to 5 liters - Designed for maximum durability and backed by a 3-year warranty - Clear surface for viewing particles and color variations - Stays cool, even after days of continuous use - Specifically designed for microtitering - Excellent speed control, even at low speeds - Speed ​​regulation up to 1100 rpm - Universal mains voltage / frequency range - Light

The two blades that open as the speed increases generate an axial flow in the container, from top to (more) bottom. Particularly suitable for stirring in narrow-necked containers, e.g. flasks.
