Why order the LT400A from LabSupplies.com
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.

Frequently Asked Questions
What sample viscosity is the LT-400A best suited to?
The LT-400A is rated for high-viscosity samples, delivering 0.9 N·m (9.0 kgf·cm) of maximum torque across a 10–300 rpm range. For markedly higher-viscosity work, choose a higher-torque LT model.
Does the stirrer keep a constant speed as my sample thickens?
Yes. Speed-feedback control continuously adjusts the motor to hold the set rpm even as viscosity rises during a run, and the 3-digit display plus LED torque indicator let you monitor loading.
