BLW1200 Heavy Duty Laboratory Mixer

Description

Speed for Large Thin Batches, Torque for When They Thicken

Set any speed from 20 to 1200 rpm and automatic feedback control holds it there as the material changes under the blade. The 1200 rpm model of the 120 W Three-One Motor series brings 1.2 N·m of torque, four times the standard line, to medium-low viscosity work at pilot scale: syrups, shampoos, and solutions in the vessels a bench mixer cannot keep turning.

Solving the Hard Problems in Pilot-Scale Medium-Low Viscosity Mixing

• Overload failures that kill the mixer: The current limiter protects the motor from burning out under load. This is an instrument you service and keep, not a throw-away mixer you replace.
• Overload shutdowns that kill the batch: The same limiter keeps the motor driving through loads that cut ordinary mixers off. Your process stays running and the batch survives.
• Speed drift as the batch thickens: Automatic speed feedback compensates for rising viscosity in real time. No manual correction, no drifting results.
• A fast mixer that runs out of torque: 1.2 N·m, four times the 40 W class at the same speeds, keeps a thickening pilot batch turning at the rate you set instead of slowing toward a stall.
• Unmixed layers in the vessel: Set your forward and reverse cycles once, 5 to 60 seconds each, and the mixer alternates automatically for the entire run. The ring-shaped regions that single direction mixing leaves behind never form.

Built for the Pilot Bench

The spark-free brushless motor runs quietly in a sealed aluminum body weighing 5.8 kg on a fixed arm rod built for the load. A 13 mm drill chuck holds ø12 shafts and the large 12-series blades, and a stop timer programmable from 30 minutes to 24 hours covers unattended runs. Part of the Heidon Three-One Motor line, manufactured by Shinto Scientific and sold and supported in the US by Kett, with every configuration backed by the One-Year Total Care Warranty covering parts, labor, and specification compliance.

Three ways to order. Motor Only is the drive unit alone, ready for the shafts and blades you already run. The P configuration adds the FS7 blade set and a 500 mm stainless steel shaft for a working setup out of the box. The S configuration adds the CS2 heavy duty stand, completing a full mixing station.

Working with smaller batches? The BLH1200 High Power Laboratory Mixer brings 0.7 N·m and the same 20 to 1200 rpm range to bench-size vessels.

Want the motor to stop the moment the cover opens? The BLW1200SAF Heavy Duty Safety Laboratory Mixer adds the interlocked full-guard cover to the same drive.
