magnetic separator

Magnets stirring usually involves a polymer coated AlNiCo or ferrite magnet and relies on the establishment of a liquid flow induced by centrifugal forces. These flow patterns involve a downward liquid motion towards the centre and an upward motion at the vessel wall. However, the strength of the magnetic separator decreases rapidly over a period of months when subjected to the high temperatures of microwave synthesis and the limited size of the vessel restricts the establishment of flow patterns

Stirring microwave synthesis

It is next to impossible to achieve good mixing with traditional magnetic stir bars in the cylindrical vessels used in microwave synthesis. So scientists in Austria have designed a new stir bar.magnetic filter bars is becoming more popular thanks to the dramatically reduced reactions times and improved yields it offers. However, as the majority of these reactions involve a small narrow reaction vessel, traditional horizontal stir magnet bars often result in inefficient mixing which can cause temperature gradients to develop and reduce product yields.

Test your compass

If you are not sure where your magnetic grid North is, you can determine which end of the compass needle is the North end by going outside at noon, when the sun is at the highest point of the sky. Hold the compass flat in your hand with the South end of the compass nearest to your body.Note the position of the compass needle. If you live North of the Earth’s equator, the North end of the needle will be pointing towards you and the South end of the needle will be pointing toward the sun. If you live South of the equator, the South end of the compass needle will be pointing towards you

Features Magnetic Separator

The magnetic particles in a magnetic separation equipment, except by the magnetic force, but also by the role of competitiveness. Competitiveness can be defined as the direction opposite to the magnetic force of all mechanical forces, including gravity, centrifugal force, inertia force and the hydrodynamic resistance and the like. In the magnetic separation process, the magnetic force of the magnetic particles is a collector, the collector also known as magnetic force; competitiveness of the magnetic particles from the magnetic stir bars, is also known from the force. Obviously, a necessary condition for the magnetic particles and non-magnetic particle separation is greater than the magnetic force of the magnetic particles suffered competitiveness
