Thank you very much for changing of syringe!
Also thank you for support my plant tour when I was in Gammatron.
Fukuroi had not had process to change syringe.
So our production team is considering how to keep cleanness of syringe.
My recommendation is as follows.
-Cleanness check of syringe is added as a PM item. Then if contamination is found, syringe should be clean up or changed.
Next step
-If appropriate exchange frequency is identified, periodical exchange may be added in PM.
If you have any questions, please let me know.
