The QHCJX series magnetic stirrer installs the magnetic transmission device at the bottom of the tank equipment, which can achieve low-level stirring inside the tank, especially in working conditions where the medium is prone to sedimentation during stirring or reactiongoodSex. The QHCJX magnetic stirrer is welded directly to the bottom of the tank due to the isolation sleeve, ensuring the integrity of the tank. The transmission shaft is short, the structure is compact, easy to disassemble and clean, zero leakage, allows for high speed, self-lubricating cooling, and can achieve online cleaning and online sterilization (CIP/SIP). The structural design meets GMP requirements.
