Unguator Standard Mixing Blade 100mL. The shaft is made of a titanium-hardened stainless steel and the winged "S" blade is composed of durable polyoxymethylene plastic. Each blade is slightly larger in diameter than the equivalent jar size, allowing the blade to sweep the inner chamber wall, creating shear and promoting optimal amalgamation. The blades also have a sharp leading edge which acts as a grinding mechanism and ensures product homogeneity. The Standard Mixing Blades achieve the finest results in all formulations.
