HUXI
ADS series high-power stirrer is a programmable top-mounted stirrer with a large LCD touchscreen display and high torque. It features a self-locking chuck, adjustable speed and time, and is used for mixing solid-liquid, liquid-liquid, or medium-to-high viscosity samples. It is primarily used in scientific research, pharmaceuticals, chemicals, petrochemicals, cosmetics, food, and biological fields.
This stirrer delivers a maximum torque of 200 N.cm and handles viscosity up to 10000 mPa.s. The microelectronic processor keeps rotating speed stable even with changing material viscosity, ensuring consistent stirring effect for long-term experiments.
The 4.3-inch touch screen works well with gloves. Screen lock function avoids accidental touch. Digital real-time speed display makes parameter recording and adjustment convenient for lab operators.
It has overload, short circuit and motor fault protection, which will auto stop and alarm abnormally. The sample temperature protection ranges from -160℃ to 600℃ to protect samples and equipment.
The plastic chuck resists organic solvent corrosion. It gives audible prompts after correct installation to avoid misalignment. The paddle penetration hole allows quick height adjustment of stirring paddles.
It supports 99-segment speed/time/rotation control and 80 groups of four-segment cycle programs. The maximum timing reaches 8 hours, fully meeting complex and continuous experimental demands.

Q: Can this stirrer work with high-viscosity samples?
A: Yes. Its max torque is 200 N.cm and it supports up to 10000 mPa.s viscosity. The stable speed system ensures normal stirring even for thick samples.
Q: Is the chuck resistant to organic solvents?
A: Absolutely. We adopt corrosion-resistant plastic chuck, which can effectively resist erosion from common lab organic solvents and extend service life.
Q: Will the machine be damaged by overload?
A: No. It has overload and short circuit protection. It will cut off power and alarm automatically to protect the motor and samples.
