[Noise Countermeasure Case] Centrifuge Stops for Unknown Reasons! What is the Cause!

[Noise Countermeasure Case] Centrifuge Stops for Unknown Reasons! What is the Cause!

The operation of multiple analysis devices is unstable and not functioning properly! Introduction of noise countermeasure examples.

At the C Research Institute, research and development of new drugs is underway, and many facilities are in operation. In these facilities, issues such as "we want to use the centrifuge continuously for 8 hours, but the equipment stops at night" have occurred. We requested each equipment manufacturer to investigate the cause of the malfunctions and prevent their recurrence. However, since the manufacturers could not identify the cause of the malfunctions, they were only able to provide temporary repairs. Additionally, repairs for equipment under warranty are all free of charge, but once the warranty period is exceeded, repairs become chargeable, and those costs cannot be ignored. The facility manager began an investigation to improve this situation. *For more details, please refer to the PDF document or feel free to contact us.*
