Yamato LT / LR-Series Stirrer

From $1,611.95
List Price From $1,806.00

LT Series stirrers include LT400A and LT500A with higher torque, LT400V and LT500B with well-balanced speed and torque, and LT400C and LT400D with high speed to support different applications

  • Highly sensitive feedback system keeps the set speed even with changing viscosity during stir
  • Maintenance free DC brushless motor
  • Digital speed indicator for accurate speed setting and confirmation
  • Noise prevention measures for optimal work environment
  • More safety-oriented design

LR500A/B Series Digital Laboratory Stirrer

  • DC brushless motor considered superior in safety as there are no brushes to cause sparks ad no brush replacement required
  • Direct-drive system reduces noise and require low maintenance
  • Achieves high torque enabling stirring of high viscosity solution
  • Digital tachometer for easy speed setting and confirmation
  • Load on the stirring shaft can be monitored by LED2 display. An overload lamp turns on when exceeding the maximum load, stopping the motor automatically.
  • Revolution feedback control function can maintain the setting rate despite change of load (especially suitable for high viscosity samples)
