The Yamato 231386 is a two-stage disc turbine propeller — 60 mm diameter for an 8 mm (φ8) stirring shaft — for LT-400 and LT-500 laboratory overhead stirrers. The dual-disc geometry improves mixing of viscous or multi-phase media. It is the matched blade for higher-shear stirring on the LT series.

Application Profile
A disc turbine creates strong radial flow and high shear — ideal for dispersing, emulsifying, and mixing viscous or multi-phase media where a simple propeller would just spin the liquid. The two-stage version (231386) stacks two discs on the φ8 mm shaft, extending that mixing over a taller fluid column for more uniform blending in deeper vessels. For lighter single-disc mixing, choose the 60 mm (231062) or 100 mm (231064) single turbines.
Frequently Asked Questions
What is the Yamato 231386? A two-stage (dual-disc) turbine propeller, 60 mm diameter, for an 8 mm (φ8) shaft on LT-400/500 stirrers.
Why choose a two-stage turbine? The stacked discs spread high-shear mixing over a taller fluid column — better for deep-vessel blending than a single disc.
Which stirrers does it fit? Yamato LT-400 and LT-500 overhead laboratory stirrers (φ8 shaft).
