For over three decades, we have specialized in providing sensitive, reliable and easy-to-use fluorometers for environmental and industrial uses. We believe we supply more of these kinds of instruments than any other company in the world.
Our job is to make your job easy and risk-free. To this end, we try to understand your application. When necessary to ensure that you get the right instrument for your application, we will run your sample solution in our lab, or in some situations, we will lend you an instrument to evaluate. Additionally, we are staffed with responsive scientists and engineers to help you after you receive your instrument.

We specialize in the measurement of fluorescent tracers, algal pigments, and other naturally occurring fluorescent compounds. For these applications we provide in-depth instrument support and we offer devices designed to enhance simplicity and improve quality.

Our company is owned and operated by the people who design, produce, sell and service our instruments, so we take extra pride in our work. If we have exceeded your expectations, please let us know. More importantly, let us know if we have disappointed you so we can make things right and so we can do better for our next customer.
