Common Questions About Heat-Collecting Temperature-Controlled Magnetic Stirrers

I. What Is a Bath-Type Temperature-Controlled Magnetic Stirrer?

　　A magnetic stirrer whose temperature-control range covers organic synthesis and whose temperature stability is ±1°C is described as a temperature-controlled magnetic stirrer. Compared with ordinary magnetic stirrers, it offers high sensitivity, strong controllability and a broad temperature range. It is widely used in advanced organic synthesis experiments, supports automated experimental stirring and is useful for mixing solutions for analytical instruments.

　　Bath-type magnetic stirrers offer quiet, vibration-free operation and rapid heating. They are useful laboratory tools in universities and colleges, environmental protection, public health, epidemic prevention, petroleum, chemical engineering and medical institutions.

　　II. Technical Features of Bath-Type Temperature-Controlled Heated Magnetic Stirrers

　　Bath-type temperature-controlled heated magnetic stirrers use surrounding heat so the vessel is fully exposed to intense thermal radiation. Heating is stated to be three times faster than with flat-hotplate magnetic stirrers. Uniform temperature and high efficiency make this design suitable for heated reactions in round-bottom flasks.

　　Key components use high-quality materials. A high-power DC motor provides high stirring torque and low noise. The specially made stainless-steel heating tube is aged at 8000C for 24 hours. Insulation resistance exceeds 1000MΩ, supporting safe dry heating. Neodymium-iron-boron permanent magnets form the rotor to provide strong attraction and torque.

　　III. Common Questions About Bath-Type Temperature-Controlled Magnetic Stirrers

　　Why does the temperature controller of a bath-type temperature-controlled heated magnetic stirrer fail to work?

　　The problem is probably a damaged temperature probe rather than the controller. Do not remove the probe from the oil bath during heating, as it can fail in less than ten minutes. Several units in our laboratory have failed this way.
