Yamato LT400AA Lt-400A Set Main Body, Stand, Rod, Stainless Steel Shaft And 60 Mm 4-Blade Propeller Overview
The Yamato LT-400A laboratory stirrer set (SKU LT-400AA) is a complete, bench-ready overhead mixing package: the LT-400A digital stirrer main body plus its stand, support rod, and a stainless-steel ø10 × 500 mm stirring shaft with 4-blade propeller. It runs from 10–300 rpm on a gearless direct-drive, 30 W DC brushless motor and is tuned for high-viscosity samples.
Speed-feedback control maintains the set speed as viscosity changes mid-run, with maximum torque of 0.9 N·m (9.0 kgf·cm). A 3-digit digital display shows set speed alongside an LED torque/overload indicator, while overload stop, a current-limit circuit, and thermal motor protection guard both the drive and your sample. Everything needed to clamp, mount, and start stirring ships in the box.
How to Choose the Right LT Stirrer
Across the Yamato LT series, the model letter sets the balance between speed and torque — higher top speeds trade off maximum torque, so match the model to your sample:
- Sample viscosity: this LT-400A is rated for high-viscosity samples (0.9 N·m (9.0 kgf·cm) maximum torque).
- Speed range: 10–300 rpm — confirm your process rpm falls inside this band.
- Shaft & vessel: the ø10 mm chuck takes standard Yamato shafts; size the propeller to your vessel.

Frequently Asked Questions
What is included in the LT-400AA stirrer set?
The set includes the LT-400A digital stirrer main body, its stand and support rod, and a stainless-steel ø10 × 500 mm stirring shaft with a 4-blade propeller and clamp — everything needed to mount and run. Sample vessels and glassware are not included.
What sample viscosity is the LT-400A suited to?
It is rated for high-viscosity samples, delivering 0.9 N·m (9.0 kgf·cm) of maximum torque across a 10–300 rpm speed range. For markedly higher-viscosity work, step up to a higher-torque LT model.
Does the stirrer hold a constant speed as the sample thickens?
Yes. Speed-feedback control continuously adjusts the motor to maintain the set rpm even as viscosity rises during a run, and the digital display plus LED torque indicator let you monitor loading in real time.
