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).

Further information

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.

 

Vacuum warping of spin coater substrate
The effect of vacuum warpage during spin coating is shown in the left hand image of a thin film of fluorescent OLED material of approximately 70 nm thickness. By eliminating the vacuum during the spin coating process a much more uniform film can be obtained (right).

In the Ossila spin coater chucks the substrates sits in a recess which holds it securely in place.

 

Changing Chucks

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.


This video shows how easy it is to remove the spin coater substrate chucks, which have a push-fit connection to the motor coupling in the spin coater, for cleaning or interchanging with other spin coater chucks.

The custom milled polypropylene chucks allow for mounting substrates of a range of varying shapes and sizes.

The recessed design holds the substrate securely in place without a vacuum, reducing substrate warpage for better film quality.

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.
