Electronic Stirrer Model 300

The Electronic Stirrer Model 300 is a motorless magnetic stirrer that operates by generating a rotating electromagnetic field in the stirring heads. The liquid to be stirred has a magnetised stirring bar placed in it. The bar and therefore the liquid, is rotated by the magnetic field produced in the heads.

The Model 300 provides great ​flexibility for use with different sizes and types of vessels; it is particularly suitable for small specialised sample holders frequently used in electrochemical and spectrometric applications.

The magnetic stirrer has several advantages over conventional motor driven stirrers:

  • The stirring heads produce less electrical noise than motor type stirrers. With no moving parts they are very reliable.

  • Multiple heads can be connected to a single magnetic stirrer controller all stirring at the same speed.

  • Stirring head size is not constrained by motor sizes.

Main Features

  • Display of stirring speeds.

  • Four Stirring Modes

    • Constant speed, clockwise.​

    • Constant speed, counter clockwise.

    • Auto reversing mode, slow acceleration.

    • Auto reversing mode, fast acceleration

  • 37 discrete stirring speeds from 100 to 1800 rpm.

  • Capture Button to allow stirrer bar pick up without having to adjust the stirring speed.

  • Memory feature allows the stirrer to operate exactly as before switch off, with soft start on power up to ensure stirrer bar pick up.

  • Three 5-pin DIN sockets allows up to twelve stirring heads (depending on type) to be simultaneously driven at the same speed. The maximum drive capacity is 15V/8 W, this allows control of up to:

  • Stirring speed independent of sample viscosity; limited only power of Stirring Head.
