Gregory S Van London - Founder

Van London Company (“VLC”) was founded in 1961 by Gregory (“Greg”) S. Van London as a distributor focused mainly on the end-users of liquid analytical equipment. Greg possessed a special dedication to providing products and services which met, and in many cases, exceeded customers’ expectations. VLC houses a full machine shop, QC Department and Assembly Department that afforded VLC the ability to customize and improve upon the products purchased from other manufacturers.

Not being satisfied with the delays and in-flexibility of then-available manufacturing companies, Greg opened pHoenix Electrode Company in 1975 as a complete manufacturing facility for electrodes. It boasted a full machine shop, a glass blowing department and production line, allowing for the complete manufacturing of special, custom and direct replacement electrodes.

The two sister-companies complimented each other, maintaining a commitment to providing quality products in a time-efficient manner to meet the customized needs of each customer. VLC focused on end-users with a specialty in harsh industrial environments, while pHoenix Electrode Company serviced the international laboratory, private-label and OEM markets. The two companies were subsequently merged into one entity in 2007, creating additional synergies for future expansion.

Today, Van London is serving world-wide industries including industrial, laboratory, biotech, food and beverage, pharmaceutical, municipalities, waste water treatment and many others, our product lines include pH, Dissolved Oxygen (“DO”), Conductivity, Ion Selective (“ISE”), Karl Fisher, Chlorine, and Oxidation Reduction Potential (“ORP”). We offer direct replacements for most major brands.

Van London’s manufacturing campus is located in Houston, Texas, USA, and employs over 150 employees. We are a registered Small Business, allowing us to contribute to larger corporation’s needs for diversity procurement fulfillment.

Committed to continuous improvements in our business, Van London consolidated, expanded, and improved our manufacturing space, resulting in 35,000 square feet of space for our state-of-the-art, stream-lined, manufacturing facility. The manufacturing plant includes sophisticated machine and glass-blowing shops, bar-code tracking technology, and other strategic investments which improve productivity and quality.

Our research & development department plays a key role in developing new products, helping Van London to remain a technology and application leader in the industry. As well, our professional sales and marketing teams help ensure high levels of customer service and satisfaction.

Since our inception, Van London Company’s goal has remained the same: to consistently produce a high quality product that exceeds each client’s unique needs in a timely fashion at a reasonable cost. It is our desire to not be another “vendor”, but a true “partner”… working closely with you to promote your success.
