Spin Coater Chucks
We stock a range of milled polypropylene (solvent safe) chucks compatible with the Ossila Spin Coater.
The interchangeable chucks have a push-fit base that fit firmly onto the Ossila Spin Coater's coupling for ease of use.
For customers wanting to use their own substrate system, we can produce custom chucks to fit your substrates. Simply contact the Ossila office with your requirements and we can determine the right chuck for you.
Alternatively you can download the '.stl' file for free to manufacture your own chuck (see below).

The spin coating chuck has a recess designed to hold the substrate securely in place by friction and centrifugal force, while allowing excess solution to escape.
This eliminates the need for a vacuum and significantly reduces substrate warpage for better film quality as shown in the figure below.
The Ossila spin coater has been designed to make it quick and easy to change chucks so that many different substrate sizes can be accommodated.
Standard 20 x 15 mm substrate and 50 mm substrate
This two-level chuck offers full flexibility across our substrate ranges. The additional corner recesses on both levels also ensure excess solution can still escape. Further more it is ideal for use with our carrier plates allowing you to adapt the chuck to work with custom or alternative substrate sizes.
