Opening Diffusion Capsules

Evacuated diffusion capsules are opened and air allowed to bleed into the capsule very slowly by the following method.

The capsule 1 is placed upon V-block 2. Rotating the handle 3 lowers the wheelhousing 4 to make contact with the capsule quartz wall. The vacuum source valve 5 is opened. Rubber saddle 6 holds the vacuum between the capsule and the wheelhousing. Further rotation of the handle starts the motor and rotates the diamond wheel to cut a slot into the quartz wall. The vacuum valve 5 is closed and the bleed valve 7 opened to admit air into the capsule. A twist with a screwdriver or similar instrument inserted into the slot completes the opening of the capsule.
