Zest CHAIRSIDE Attachment Processing Material Mixing Tips, 15 Pack · 18 mL Cartridge

• Mixing Tips — The disposable part: used mixers are discarded and the cartridge is resealed with its original cap.
• Intraoral Tips — Added after the mixer, to reach into the mouth.
• Dispensing Guns & Syringes — The reusable part, chosen by cartridge size and mixing ratio. Material comes out easily through a mixer of the right size; one maker warns that excessive force can rupture the cartridge or break the gun.
• Mixing Bowls & Dishes — For material mixed by hand, where a cartridge and tip are not involved.

Fit: makers' instructions name the tip for each cartridge by colour and size, such as a yellow tip for a 50 ml cartridge and a brown tip for a 10 ml one. Some static mixers carry a built-in metal needle tip of a stated gauge, such as 17 or 19 gauge, for more precise placement.

First material out: makers instruct users to express a small amount onto a pad first, to ensure an even mix of base and catalyst.

Gloves: sulfur from natural latex gloves can contaminate the platinum catalyst of a vinyl polysiloxane and hold up its set, and the end of a mixing tip is one of the things a review names as not to be touched with latex gloves on.

Where the voids come from: a review lists mixing of base and catalyst, loading of the tray or syringe, the syringing itself, and working past the working time.
