High Powered Lab Homogenizer Serves Many Functions

Lab homogenizers are offered  in several power ratings designated by wattage, recommended processing volumes and speeds. Homogenizer applications include blending, emulsifying, dispersing, cell disrupting, particle reduction and similar processing steps.   They are widely used in labs, universities and industries. High powered lab homogenizers such as the CAT Scientific X1740 homogenizer drive motor are also capable of performing more functions when coupled with the CAT DK40 flow-through chamber and AX60 analytical mill.

The powerful 1700-watt X1740 lab homogenizer drive is used when research projects involve processing samples from  500 ml to 20 liters in volume.  Designed for both research and pilot-plant applications it operates at user-controlled step-less speeds from 2,500 to 23,000 RPM with speed indicated on the LED display.

Important accessories included (unless declined by the purchaser) to support safe operating conditions  are the recommended stand and crossover clamp for stability, and wrenches for switching out the rotor and stator assemblies.  These assemblies comprise the homogenizer generator, the part of a lab homogenizer that does the work.

Powerful Lab Homogenizer Handles Range of Sample Viscosities

The CAT X1740 high powered lab homogenizer can be used with the full range of CAT Scientific’s  dispersing tools (generators) from 6  to 40 mm in diameter and immersion depths from 55 to 300 mm.  They are precision machined to handle four basic sample viscosities, and are designated as F for fine, N for low viscosity, V for medium viscosity and M for knife applications.  The CAT dispersing tool application table categorizes recommended uses.

Switching out generator assemblies is simplified allowing researchers to process a variety of sample properties using the X1740 drive motor.  Procedures for doing this are explained in our video  how to change homogenizer generators .  Rotors and stators have extremely sharp machined edges so be careful when handling them.

Comprehensive details on setting up, using and maintaining the CAT X1740 high powered lab homogenizer are found in the instruction manual.

Lab Homogenizer Accessories Improve Return on Investment

Lab and pilot plant homogenizers such as the CAT X1740 have other functions that make them an attractive investment.  A perfect example is the DK40 flow-through chamber accessory ideal for extending the exposure of samples to the homogenizing action and  performing in-line sample processing.

Why is this? When homogenizing using flasks the amount of sample exposure to homogenizing action is controlled by the speed of the drive motor and the length of time samples are processed in the flask.  But when a flow-through chamber is used it can serve as a pump to constantly draw in then discharge the sample, either to the same beaker or to another destination.

The 5000 liter per hour DK40 flow-through chamber is equipped with a cooling jacket and is mounted directly to a homogenizer drive motor operating to 23,000 rpm.  Both assemblies are firmly attached to a horizontal mounting plate.  Restricting outflow extends exposure time in the chamber.

Grinding Mill Processes Small Samples

Another accessory is the AX60 analytical mill when attached to the drive motor in much the same way as a standard rotor-stator homogenizer assembly. The two-part unit is fabricated of stainless steel.  The top portion of the assembly houses grinding blades powered by the drive motor; the  lower grind mill chamber holds up to 180 cc of the sample to be pulverized.  Top and bottom portions of the analytical mill are coupled then clamped together to provide a dust tight assembly.

Because the pulverizing mill generates heat a cooling system is incorporated in the design to circulate liquid nitrogen or chilled water.  The cooling medium passes through inlet and outlet ports built into both the top and the bottom portions of the grinding chamber assembly.
