BL3000 Laboratory Mixer

Description

High-Speed Dispersion for the Everyday Bench

Set any speed from 50 to 3000 rpm and automatic feedback control holds it there as the material thickens, thins, or does something you did not plan for. The 3000 rpm model of the 40 W Three-One Motor series brings 0.1 N·m of torque to low viscosity work in bench-size batches: water-thin solutions, oils, and emulsions, and the batches that change as they run.

Solving the Hard Problems in 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 high-speed mixer that lurches to full speed on start: Power-on always begins at the lowest speed, so the blade meets the liquid gently and you bring it up to 3000 rpm on your terms, not the switch’s.
• 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 BLH3000 High Power Laboratory Mixer doubles the torque to 0.2 N·m in the same body.

Want the motor to stop the moment the cover opens? The BL3000SAF Safety Laboratory Mixer adds the interlocked full-guard cover to the same drive.
