The Yamato LT-400CA is the complete-set configuration of the LT-400C overhead stirrer — the LT-400C main body plus the stand, rod, stainless-steel shaft and 60 mm 4-blade propeller packaged ready to run. It is the same high-speed, middle-to-low-viscosity overhead stirrer (25–1200 rpm, 0.3 N·m / 3.0 kgf·cm, 35 W brushless motor) delivered as a turn-key rig rather than a bare main body.

Author confidence note: stirrer, shaft and 60 mm propeller are itemized in the manual; the stand/rod correspond to Yamato's Y-type rack (25 mm x 725 mm) — confirm the exact part supplied in the set with Yamato at order.
Application Profile
- Higher-speed mixing of thinner samples, turn-key — dilute solutions, suspensions and dispersions up to 1200 rpm, mounted-ready with stand and rod.
- Overhead stirring of small-to-mid vessels — top-driven mixing where a magnetic stir bar cannot couple.
- Quiet-bench operation — noise-prevention design for shared labs.
Overhead vs magnetic — pick the LT-400CA when overhead drive is needed at higher speed for low-to-middle viscosity work as a complete rig. Step down to the LT-400BA (15–600 rpm) or LT-400AA (10–300 rpm, 0.9 N·m) as viscosity rises.
Design Architecture
The LT-400CA is the LT-400C drivetrain on a stand. A 35 W DC brushless motor turns a ø8 mm SUS drill chuck through feedback control that holds the set speed as viscosity changes mid-stir, delivering 0.3 N·m. Load and speed show on a 4-digit digital readout with overload indication and a 20%-graduated torque indicator.
Protection layers a current-limiting circuit, a thermal protector (110 °C coil cutoff, ~30 min recovery) and a safety cover over the rotating chuck. Because this is the lowest-torque / highest-speed LT-400 build, a genuinely viscous sample will trip the overload sooner than the LT-400AA/BA would. The included stand, rod, 500 mm stainless shaft and 60 mm 4-blade propeller complete the rig.
Frequently Asked Questions
What speed and torque does the LT-400CA deliver? 25–1200 rpm with 0.3 N·m (3.0 kgf·cm) — the high-speed, middle-to-low-viscosity build in the LT-400 line, driven by a 35 W DC brushless motor.
What comes in the complete set? The LT-400C main body, stand, rod, stainless-steel stirring shaft (ø8 x 500 mm), 60 mm 4-blade propeller, clamp holder, safety cover, chuck handle, operating manual, and warranty card.
How does the LT-400CA differ from the LT-400C? The LT-400CA is the turn-key stand-mounted rig; the LT-400C is the bare main body only. Choose the LT-400CA when no stand already exists.
What if my sample is viscous? Because this is the lowest-torque, highest-speed LT-400 build, a genuinely viscous sample will trip the overload sooner — step down to the LT-400BA (15–600 rpm) or LT-400AA (10–300 rpm, 0.9 N·m) as viscosity rises.
What power does it require? Single-phase 100–120V ±10%, 50/60 Hz, 200VA. There is no 220V variant in the source.
Ordering & Configuration
In the box: LT-400C main body, stand, rod, stainless-steel stirring shaft (ø8 x 500 mm), 60 mm 4-blade propeller, clamp holder, safety cover, chuck handle, operating manual and warranty card — a complete stand-mounted stirring rig.
Optional accessories: alternate propellers (40 mm, 75 mm, 100 mm two-blade, turbine/disc types), glass blade, narrow-port blades — all sold separately.
At $1,845.00 the LT-400CA is a direct add-to-cart complete set. Choose over the LT-400C main body ($857.50) when no stand exists. Supply is 100–120V only; no 220V variant in the source. Confirm propeller size against vessel geometry.
Warranty: one year from purchase per Yamato terms.
LT-400 sets: LT-400AA (10–300 rpm) · LT-400BA (15–600 rpm) · LT-400CA (25–1200 rpm, high speed, this product). Main bodies only: LT-400A / B / C.
