While cleaning the Newport AJS254-0.5K-NL Adjustment Screw, I sonicated three Newport AJS254-0.5K-NL Adjustment Screws in isopropyl alcohol at 30°C for 20 minutes. When I came back, I discovered the tip had dissolved. I thought the tip was stainless steal like the body, but it might not be. I reached out to Newport for clarification. If the crusher does work (we at least one screw on hand), we will need 3 more replacements.
