Checking the effect of cleanroom washing

Measuring the particles

After washing the test samples of USCultrasonic cleaning completed and IPAIPA cleaning completed, as well as untreated test sample, with ultrapure water, we measured the number of particles floating in the ultrapure water.
The higher the cleaning power, the fewer the floating particles will be.

Test sample: SUS303 φ19×20
Test method: Automatic liquid particle counter measurement
