Magnetic Stirrer Torque

Magnetic Stirrer an overview ScienceDirect Topics.

A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic fieldThis device is used to make a stir bar immerse in a liquid quickly spin or stirring or mixing a solution for exampleA magnetic stirring system generally includes a coupled heating system for heating the liquid Figure 6.

Brand REMI Features PMDC motor for higher torque even at low speeds Better speed regulation even with small volume and low speeds Accurate stepless speed control maintains excellent speed stability.

The magnetic stirrer is a stirrer made of highquality magnetic steel covered with PTFE which is heatresistant wearresistant and corrosionresistantThe mixing work is carried out in a sealable container which is ideal and convenient to useThe magnetic stirrer can be integrated with auxiliary heating device which greatly facilitates.

These stirring system possess integrated magnetic couplings in 6 sizes to transmit a maximum torque of 60 to 4000 NcmThe magnetic stirring systems can be equipped with different stirring elements depending on your requirementsMagnetic Stirrer Models The rotation speed details listed in the table are the default numbers.

This Customized compact magnetic stirrer with SS topPermanent Magnet DC PMDC motor used for high torque at low speedAlso this motor maintains speed when viscosity and volume changeAccurate speed control with smooth variation display.

This magnetic stirrer for spectroscopy uses a magnetic field to transmit torque to a Teflon coated magnetic bar inside of a sample cellDue to its small size the stirring bar fits into even 2 mm thick cuvettesSince the rotation of the stirring bar is achieved with a magnetic field the stirrer can be used with hermetically sealed cells.

Torque range 50 to 5400 Ncm Temperature range 50C to 500C Pressure range full vacuum up to 500 bar 6000 psi Materials stainless steel Hastelloy Tantalum Titanium ceramic others.

Under normal fermenter operating conditions increasing the stirrer speed and gas flow rate improves the value of k L aTypical data for k L a in Newtonian fluids of varying viscosity are shown in Figure 10The strong dependence of k L a on stirrer speed is evident from Figure 1010a in this system doubling the stirrer speed N i resulted in an average 4.
