Welcome!

We are located in Skokie, Illinois, just up the road from downtown Chicago on the Yellow Line. Our state-of-the art lab is where we make first-ever adsorbents to purify your drinking water. Using pioneering technology and brilliant minds, we convert corn into DEXSORB®.

Take a look around (goggles optional) and check out where our science happens.

Test this, analyze that

We pair our chemistry expertise with best in class analytical capabilities. The result: fast lane development. Experimental design and measurements loop around the lab to provide realtime advances. The faster we can test and analyze, the quicker we can make your water pure.

Formulations

DEXSORB safely adsorbs the pollutants other filtering media miss. Our formulations target chemicals at concentrations below one part per billion. With DEXSORB, we are making tap water drinkable again, sustainably, and affordably.

DEXSORB

Developed in 2016, DEXSORB is broadly effective against hundreds of diverse chemical compounds, including BPA, pesticides, and pharmaceuticals.

DEXSORB+

We developed DEXSORB+ in 2018 specifically to target PFAS compounds by adding a positive charge to our original DEXSORB formulation.

Why science by nature?

We say ‘science by nature’ because we use cyclodextrins, a natural adsorbent made from corn, as the mainstay of our adsorbents. You know them from products like Febreze; they are nanometer scale cups perfectly suited to capture and remove small molecule contaminants.

Why is DEXSORB special?

First ever: It’s a first ever use of cyclodextrins in water.

Renewable + reusable: Equals the definition of ecofriendly.

Cost-effective: Corn is cheap, fast and longer lasting.

Versatile: Applications range from personal water bottles and home filtration to municipal water treatment.

How does DEXSORB work?

Basically, it’s a Venus flytrap for micropollutants. Small molecule chemicals floating in water are drawn to our cyclodextrins; to be adsorbed and locked up.

Speed kills (micropollutants)

A hallmark of our adsorbents is their super fast removal of micropollutants. This facilitates lower dosing, high flow rates, and decreased fouling by other materials. Fast-acting adsorption also allows for flexible uses such as in-home and more economies for municipal plant operations.

How is DEXSORB made?

DEXSORB is formed by grouping sub-nanometer cyclodextrin cups into a yellow powder adsorbent. For scale: a sugar cube would hold one hundred quintillion cups – 1020! That is a lot of traps at work in a small volume.

A 21st century chemistry set

Using a proprietary toolbox, we are able to design adsorbents that selectively target tiny toxins. Sub-nanometer pollutants need modern technology solutions.

Catch ‘n’ release

A major advantage is that we can re-use our adsorbents with a simple wash, allowing for efficient disposal of concentrated waste.
