Hello and thank you for visiting.   LUM (pronounced loom as in illuminate) makes instruments allowing you to measure particle size, stability, shelf-life, all other dispersion instability processes, in a whole new way. Please browse our products to see for yourself how we may be of service to you.

Dispersions, Emulsions, Suspensions: With the STEP Technology™ based LUMiSeries of instruments you can analyze your emulsion, suspension, dispersion instantaneously across the entire sample. Measure particle size, stability, shelf-life, and all colloidal stability and instability phenomena directly. High concentration, low concentration, high viscosity, low viscosity, high temperature, low temperature, nano particles, micron particles. The choice is yours. Understand what, if, how, why, and when.

Materials - Adhesion, Cohesion: The revolutionary LUMiFrac adhesion measuring technology (CATT) ensures accurate, fast, and repeatable adhesion measurements and data. Do more with less.

Providing real-world solutions in the areas of: emulsion stability, suspension stability, particle size, emulsion particle size, suspension particle size, predicting emulsion shelf life, predicting suspension shelf life, flocculation, aggregation, coalescence, magnetic particles, nano-particle dispersions, syneresis, dewatering, phase separation, demulsification, emulsification, sediment compressibility, quality control, product optimization, adhesion and cohesion of adhesives, sealants, paints, coatings, inks, tensile strength, pull of force, fatigue testing, and other areas for research and development.

The Whole Picture

Have you ever heard of the old story about the blind men and the elephant? In case you have not, the essence of the story is this: unless you see the whole picture, you may reach an incorrect conclusion.

Traditional analytical techniques only allow you to look at one unknown point in your sample or give you one data point. For simple products this may work, but for complicated emulsions and suspensions it may lead to the well-known "the blind men and the elephant analysis" syndrome.

This is why we invented the STEP Technology™. It is the only technology that allows you to look at and analyze your whole sample instantaneously from top to bottom. So you can analyze and understand every aspect of your dispersion, emulsion, or suspension. So you will never miss anything. So you can be confident in your results.

STEP Technology™ - giving you the complete picture


The Unabridged Merriam-Webster Dictionary defines direct as

di·rect - adjective: from point to point without deviation : by the short or shortest way
“Direct.” Webster's Third New International Dictionary, Unabridged. 2014.. Web. 05 Mar. 2014.

With the STEP Technology™ based instruments you can measure and analyze every stability & instability process directly without knowing anything about the sample. In addition you can measure shelf life directly and accurately.

No need for refractive index, density, viscosity, concentration, dielectric constants, surface tensions, interfacial tensions, etc, nothing. Just place your sample in the instrument and analyze its stability directly.

Knowledge is Power

Dispersions are beautiful but often complex systems with many different paths leading towards stability or instability. Why not have the ability to measure and understand them all?

With the STEP Technology™ you can easily, accurately, quickly measure, and quantify any and all dispersion stability or instability phenomena. Be it a change in the particle size distribution, an increase in the creaming rate of your emulsion, or your suspension flocculating. It will give you the true state of your dispersion.

After all, you want more than just numbers. You want answers so you to optimize your emulsion or suspension, as well as prevent and eliminate product performance and quality issues before they occur.

By looking and analyzing your whole sample instantaneously from top to bottom, complex problems suddenly become simple.


Who? LUM is a small family owned company focused on advancing the science of dispersion and adhesion analysis.

What? We make the LUMiSizerLUMiFugeLUMiReader MWLUMiReader X-Ray, and the LUMiFrac. In addition we offer educational seminars, consulting and analytical services.

Philosophy? Part 1. It is our goal to design and make analytical tools that are simple to sue and allow you to measure physical properties of emulsions and suspensions directly and correctly.

Philosophy? Part 2. To stand behind our products and give you all the support you need. After all, a company, product, and technology are only as good as the people who stand behind it.

Thank you for your time and consideration.
