The Yamato LT-500BA is the complete-set configuration of the LT-500B overhead stirrer — the higher-power (65 W) LT-500B main body plus the stand, rod, stainless-steel shaft and 60 mm 4-blade propeller packaged ready to run. It is the same higher-speed, middle-viscosity overhead stirrer (25–1200 rpm, 0.5 N·m / 6.0 kgf·cm) delivered as a turn-key rig rather than a bare main body.

Notes: figures follow the LT400A/500B manual (assigned source: 0.5 N·m, 65 W); the marketing brochure lists 0.6 N·m / 30 W — confirm with Yamato if load-bearing. Stirrer, shaft and 60 mm propeller are itemized in the manual; the stand/rod correspond to Yamato's Y-type rack — confirm the exact part in the set.
Application Profile
- Higher-speed middle-viscosity mixing, turn-key — the 65 W LT-500 drive at 25–1200 rpm for solutions and moderate suspensions, 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-500BA when overhead drive is needed at higher speed for middle-viscosity work as a complete rig; step to the LT-500AA (15–600 rpm, 0.9 N·m) when a thicker sample needs more torque at lower speed.
Design Architecture
The LT-500BA is the LT-500B drivetrain on a stand. A 65 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 0.5 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 (90 °C coil cutoff, ~30 min recovery) and a safety cover over the rotating chuck. The included stand, rod, 500 mm stainless shaft and 60 mm 4-blade propeller complete the rig; the set runs on a 400VA supply.
Frequently Asked Questions
What is the difference between the LT-500BA and the LT-500B? The LT-500BA is the complete set — the LT-500B main body plus the stand, rod, stainless-steel shaft, and 60 mm 4-blade propeller, packaged ready to run. The LT-500B is the bare main body and requires a stand.
What speed and torque does the LT-500BA provide? 25–1200 rpm with a rated torque of 0.5 N·m (6.0 kgf·cm) per the manual, driven by a 65 W DC brushless motor with feedback control that holds the set speed as viscosity changes.
What samples is it suited to? Higher-speed, middle-viscosity mixing — solutions and moderate suspensions in small-to-mid vessels. For thicker samples needing more torque at lower speed, step to the LT-500AA (15–600 rpm, 0.9 N·m).
Is there a 220V version? No. The supply is 100–120V only (400VA); no 220V variant exists in the source.
What ships in the box? The LT-500B 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.
Ordering & Configuration
In the box: LT-500B 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 $2,100.00 the LT-500BA is a direct add-to-cart complete set. Choose over the LT-500B main body ($1,036) 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-500 sets: LT-500AA (15–600 rpm) · LT-500BA (25–1200 rpm, this product). Main bodies only: LT-500A / B. Lower-power siblings: LT-400 sets (35 W).
