Description
The Ritter ZWM 13 is a helical static mixer that blends two-component adhesives as they travel through a spiral element stack. The bayonet base twist-locks onto standard 50 mL cartridges, and the spiral elements fold resin and hardener into a uniform bead by the time material reaches the tip. It suits 1:1 and 2:1 systems run on manual or pneumatic cartridge guns.
Where the Ritter ZWM 13 fits
Reach for it on assembly bonding, gasketing, potting, and repair work where a two-part epoxy, urethane, or methacrylate has to leave the cartridge already mixed. The bayonet fitment matches the common 50 mL format used across many adhesive brands, so one mixer style covers a range of cartridges on the bench. Helical mixing handles general-purpose viscosities well and lays down a steady, even bead.
How the Ritter ZWM 13 performs
The spiral element seats tightly in the housing, which limits bypass so both parts blend across the full length of the tube. The plastic body dispenses cleanly and is single use, so a fresh mixer on each cartridge keeps a partly cured tube from contaminating the next pour. Keep spares staged so a run never stops for a tip change. Because each tube threads on and off quickly, an operator can swap a fresh mixer between cartridges in seconds, and the consistent bead reduces rework on parts that have to seat right the first time.
