Enough power to mix solutions up to 20,000 cps...

This mixer touts a powerful 1⁄10-hp maintenance-free brushless DC motor that provides 142 in-oz of torque—enough power to mix solutions up to 20,000 cps or up to 6.6 gallons (25 liters). The through-shaft housing and motor design allow easy impeller height adjustments and results in less downtime in between sample or impeller changes. The rpm of the motor is displayed and controlled to ±1 rpm or 3% of the reading (whichever is greater) so you can be certain of repeatable and accurate mixing at all viscosities. The overload protection system protects your mixer if the torque exceeds the mixer ratings.

One-touch reversing and other features...

The one-touch reversing feature allows your solutions to be thoroughly mixed faster by reversing the direction of the mixing impeller and giving a new mixing profile to the system. The timed cycle feature provides the ability to control vortexing and minimizes aeration of the solution by reversing between clockwise and counterclockwise stirring. The maximum cycle time is 2000 seconds (33 minutes) in increments of 1 second.

Countdown timer can be easily set from 1 minute to 2000 minutes (33 hours) in 1-minute increments. The mixer immediately stops when the timer reaches “0” and gives three beeps to alert when complete.

The innovative sample light illuminates the mixing area to show how well the solution is being mixed so you can make adjustments to the speed, mixing direction, or impeller.

mixer head, adjustable chuck (accepts rod up to 3⁄8" [9.5 mm] dia), chuck key, mounting support rod, external power supply, and grounded power cord with plug assembly.

  • Q:

    Dear Personnel,

    I am looking for lab high speed mixer to assimilate cowles mixer in production. What do you recommend on mixer that can retain its set speed even at different viscosity? Will this be suffice or do you have any alternatives as well?

      Fluid handling has many variables. The shape and size of a container, the impeller size and shape, and motor all play a part in putting a complete and appropriate system together. Please contact our technical application specialists for additional assistance (contact information can be found on the product web page).
