Claim:
1. An injection cartridge apparatus comprising: reversably sealable barrel configured to withstand high pressure and/or high vacuum at elevated temperatures, the barrel having a cylindrical internal circumferential surface enclosing a hollow interior with a proximal end and an open distal end, the proximal end having structure with a reversibly sealable outlet to selectively seal or provide access to the hollow interior of the barrel; piston within the barrel that sealingly engages the distal end of the barrel, the piston configured to be longitudinally moved along a portion of the cylindrical internal circumferential surface such that a portion of the hollow interior between the proximal end and the piston changes volume by movement of the piston, the piston and the barrel having locking structure with a locked position and an open position, where the locked position prevents movement of the piston in barrel, and the open position allows movement of the piston in the barrel.
