Knowledge is Power – Use it!

“I currently manage two ultrasonic clean lines and in my quest to acquire more knowledge about cleanliness, I came across the Handbook for Critical Cleaning. It is a great help for me and it is a source of valuable information.

The Handbook for Critical Cleaning is a must have for all seeking to achieve optimum cleanliness and maintain it.”

Upcoming Programs

FDA Public Workshop  - Additive Manufacturing, Medical Devices
The FDA will hold a public workshop with interactive discussion on technical considerations of 3D printing of medical devices. 

“The purpose of this workshop is to provide a forum for FDA, medical device manufactures, additive manufacturing companies, and academia to discuss technical challenges and solutions of 3D printing.  The Agency would like input regarding technical assessments that should be considered for additively manufactured devices to provide a transparent evaluation process for future submissions.”

Critical cleaning is an important factor in device manufacture; and Ed Kanegsberg has been asked to be a break out session moderator. We think you should consider attending the conference. And, of course, we’d love to discuss this important issue with us.

The workshop will be held October 8 – 9, 2014 at the FDA White Oak Campus in Silver Spring, MD. You can arrange to attend on-site or participate on-line.
