The magnetic stirrer is a laboratory instrument that is used for liquid mixing, mainly for stirring or simultaneously heating and stirring liquids or solid-liquid mixtures with a certain viscosity. ATO hot plate magnetic stirrers are available with 1 litre, 3 litre, and 5 litre, and comes with adjustable heating temperature up to 380℃ and stepless speed control 0-1600 rpm, convenient operation, fast heating, uniform stirring and high durability.
The heating mantle is a kind of general heating instrument in the laboratory. It is composed of a hemispherical heating inner cover made of alkali free glass fiber and metal heating wire and control circuit. The heating mantles feature fast heating, simple use and high durability and it has magnetic stirring function to ensure the heating evenly. There is a wide selection of capacities, 100ml, 500ml, 1000ml...5L for meeting different heating requirements. These heating mantles with magnetic stirrer are ideal instrument for accurate temperature control and heating test.
A magnetic stirrer also known as magnetic mixer is a kind of laboratory equipment which is mainly used for stirring or heating stirring in low-viscosity liquid or solid-liquid mixing experiments. A rotating magnetic field is generated under the container plate, and the principle of homosexual repulsion and heterosexual attraction is used to push the magnetic stirring rod in the container to rotate rapidly, thereby achieving the purpose of stirring. The plate usually has a heating function to meet more experimental needs
The lab magnetic stirrer is usually used in the chemical and biological fields, and it is suitable for airtight containers or closed systems. It doesn’t need a complicated rotating seal structure like an electric mixer, and there is no need to maintain the rotating motor frequently or replace easily worn parts. It is quieter, more efficient, more wear-resistant than electric stirrers, and is not easily damaged (except for the simple bar magnet itself). The magnetic stirrer is more suitable for glass containers, because glass does not significantly affect the magnetic field, and it is easy to observe the stirring.
Just now, you learn the functions and characters of magnetic stirrer. Now let’s move to the features of magnetic stirrer.
In addition to these features, magnetic stirrers have other features. Magnetic stirrers are mainly used for liquid dissolution, heating and batching in pharmaceutical, food and other industries in actual life and work. The role played by the magnetic stirrer is incomparable to that of the ordinary stirrer. The magnetic stirrer can basically liberate the hands in the process of liquid stirring. And for some liquids that need temperature control, the stirring temperature can also be changed at will for better liquid mixing. For some liquids (like oil), the viscosity will change during the stirring process, and the viscosity gear needs to be adjusted to keep the speed constant.
Turn on the power, the cup is ready, open the lid of the stainless steel container, place the cup in the middle of the stainless steel container, add heat transfer oil or silicone oil to the stainless steel container to the appropriate height, and put the stirrer into the cup solution. Turn on the power switch, the indicator light is on, turn the speed regulating potentiometer clockwise, and the stirring speed is from slow to fast. Adjust to the required speed.
When heating, connect the temperature sensor probe, clamp the probe on the bracket, move the bracket so that the temperature sensor probe is inserted into the solution not less than 5 cm, but can not affect the stirring, turn on the temperature control switch, set the desired temperature, press On the temperature controller +, - set the temperature to be constant temperature, the digital display value on the meter head is the actual temperature in the cup, the heating stops, the automatic constant temperature, the heating magnetic stirrer can continuously heat the constant temperature for a long time.
If there is a jumping phenomenon in the stirrer during work, please turn off the power and then turn it on again. The speed is from slow to fast, and it can be adjusted to resume normal work.
