Stirrers

Supplier: VWR Collection

Designed for applications requiring exceptional accuracy, stability, and repeatability these magnetic hotplate stirrers are equipped with superior heating and mixing capabilities. With temperature ranges up to 500 °C and stirring speeds reaching 1600 rpm, the VWR® magnetic hotplate stirrers are equipped to handle any research, academic and industrial application. Available in two sizes.

Supplier: VWR Collection

Cylindrical, with Alnico V magnetic core.

Supplier: VWR Collection

PTFE covered, strong Alnico V magnetic core. Smooth surface with rounded edges which enhance agitation effect even at low speeds. Inexpensive, high performance.

Supplier: VWR Collection

PTFE coated, strong Alnico V magnetic core. Round, smooth surface. For use in the smallest containers.

Supplier: VWR Collection

PTFE. Blades fit PTFE stirring shaft; hole Ø 6,5 mm, 3,2 mm thick. Inert and non scratch. The smooth surface prevents contamination and makes cleaning easier.

Supplier: VWR Collection

PTFE covered, strong Alnico V magnetic core. Smooth surface. Very effective stirrers, especially at low speeds.

Supplier: VWR Collection

Compact stirrers with a ceramic glass plate provide excellent chemical resistance. Units feature digital error code display, a 'hot' top indicator to warn users that surface is hot, a fixed safety circuit that shuts off the heater if temperature rises above 550 °C, and three operating modes to choose from (standard, safe and adjustment protection). Stirrers have a speed display scale and optional capability to connect directly to a PT1000 temperature sensor; when using this functionality, control accuracy in the medium is ±0,5 °C.

Supplier: VWR Collection

Laboratory stirrers that are ideal for simple stirring tasks, suitable for quantities up to 25 L (VOS 40 digital), or for intensive stirring tasks for quantities up to 40 L (VOS 60 control). Due to microprocessor-controlled technology, the stirrers automatically adjust the speed within the speed range of 0/30 to 2000 min⁻¹.

Supplier: JM SEPARATIONS

The Avantor 10/20 L Magnetic Mixer is a robust, flexible, high-quality, expert-designed solution for small volume single use mixing needs up to 20 L.

Supplier: VWR Collection

These microprocessor-controlled, large capacity stirrers are ideal for high volume applications. There are two models to choose from depending on capacity required. Their powerful magnetic drive is capable of mixing high viscosity materials, the stainless steel base offers durability and added stability. Ideal for biotech, pharmaceutical, university and industrial pilot-scale applications. Other applications include mixing viscous materials, polymers and pilot-scale work.

Supplier: VWR Collection

Compact stirrers with a chemically resistant ceramic top. The elevated control panel minimises contact with spills. Complete with fitting for retort rod.
