AI Technical Summary
In the case of high-viscosity solutions or large-capacity beakers, the rapid rotation of the magnetic rotor in traditional heating magnetic stirrers causes lateral displacement or slight vibration of the beaker, which affects the stirring efficiency and heating uniformity, and may even lead to solution splashing or beaker damage, especially in long-term high-temperature stirring reactions.
A heating magnetic stirrer with a fixing function was designed. The beaker is dynamically fixed by a limiting clamp and a motor-driven bidirectional threaded rod system to prevent lateral displacement during high-speed rotation. Combined with a detachable fixing clamp and lifting rod, the stability of the beaker on the heating plate is ensured.
It improves the overall stability of the beaker during heating and stirring, avoids beaker displacement and splashing, reduces operational risks, and improves operational safety and heating uniformity.
