Create access ports, also known as through-holes, using manual commercial punchers available for biopsy or general use. Punch the devices on top of the green cutting board to extend the lifetime of the puncher blade and to avoid marking the table. Solvents like ethanol, isopropanol and acetone can be used as lubricants to facilitate the cutting and result in a cleaner surface. | |||
Clean well the place before leaving. Dispose all cellophane liner used. Be sure no residues of PDMS are left in the work areas, and place all PDMS residues in the C-waste container. | |||
