You don't want to start a crown procedure with a two-thirds empty cartridge, but it's too much to throw away. Save up to 30% on your cost of VPS impression material by combining partially used cartridges with the innovative Lock-n-Reload coupler. Use one coupler and an extruder gun to quickly make full cartridges from a batch of "leftovers".
- Saves motion spent switching material cartridges on the fly.
- Keyed design eliminates the chance of accidental cross-mixing of impression materials during refills.
- Twist-lock prevents cartridge separation during transfer.
For use with high-performance (rounded flange) automix cartridges. 20 blue disposable plastic couplers per pack.
