BL1200 Laboratory Mixer

Description

Speed for Thin Batches on the Everyday Bench

Set any speed from 20 to 1200 rpm and automatic feedback control holds it there as the material thickens, thins, or does something you did not plan for. The 1200 rpm model of the 40 W Three-One Motor series brings 0.3 N·m of torque to medium-low viscosity work in bench-size batches: syrups, shampoos, and solutions, and the batches that change as they run.

Solving the Hard Problems in 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 loses its speed: Feedback control keeps a thickening solution 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 Everyday Bench

The spark-free brushless motor runs quietly in a sealed aluminum body weighing just 2.0 kg, a design unchanged in its essentials since the first Three-One Motor of 1966. A keyless collet chuck makes shaft changes fast, the simple safety cover ships in the box, 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 stand, completing a full mixing station.

Need more torque at the same speeds? The BLH1200 High Power Laboratory Mixer more than doubles the torque to 0.7 N·m in the same body.

Want the motor to stop the moment the cover opens? The BL1200SAF Safety Laboratory Mixer adds the interlocked full-guard cover to the same drive.
