The 150 mm SPIN150i spin coaters come standard with a fragment adapter and vacuum chuck. (For the 200 mm spin coater you have the option between a vacuum chuck for 200mm or a vacuum chuck for smaller substrates that fits the fragment adapter.) The fragment adapter has a 10 mm opening. It can easily be pressed over the vacuum chuck and is ready for spin coating. Optionally we also offer fragment adapters with a 1 mm or 2.5 mm opening.
