Dear Cleanroom Users, On behalf of the staff here at Birck, I just wanted to express our sincere appreciation for your diligent efforts to keep the cleanroom in top condition. We have observed a tremendous improvement in cleanliness in the hoods and around equipment. It is through your focused efforts that we are now enjoying a cleanliness level (and lack of clutter) that is truly worthy of our world-class facility. Thank you for your sustained efforts! The entire staff appreciates your support! Best regards, Ron
