While most membranes supplied by Silson are used as simple sample supports for x-ray or electron beam imaging, in some applications they are used as vacuum windows or differential pressure windows, with a different pressure on either side of the membrane.
In relation to this, we offer a mounting service at Silson by one of three methods:
We usually use Loctite 9492 low out-gassing epoxy for gluing of our membranes into mounts. We always consider the best shipping methods for your mounted assembly: this might be a standard shipper or capsule as with our usual orders, or if the mount or flange has hole fittings, then we might be able to screw them down to their container.
Here you can see some examples of custom mounted membrane orders we have completed:
Aluminium coated membranes (left) mounted into custom mounts and bolted down into a box and uncoated membranes (right) mounted into custom mounts and packaged in our standard gelatin capsules, both for SPECS Surface Nano Analysis GmbH
For the orders below, we used metal tins (screw base and lid), to ensure the mounted membranes remained secure and clean during transport:
We are able to have the DN40 CF flange above machined to accept your preferred window, the below illustration is for a 14 mm frame with a 10 mm membrane:
And finally, here are some examples of our standard mounts and along with some technical drawings:
