ASCO Introduces Space-Saving O55 Series Isolation Valves For Analytical and Medical Instruments

Florham Park, New Jersey, U.S.A. - December 19, 2016 - ASCO has introduced the 055 Series line of chemically inert PTFE isolation valves for analytical and medical instrument applications that require space-saving components.

"Our new 055 Series isolation valves incorporate a form factor that is half the height of competitive products, making them ideal for benchtop liquid chromatography, DNA sequencing, and liquid sample preparation systems that are used in laboratories with limited space," said Robert W. Kemple, Jr., executive vice president, sales and marketing - Americas, ASCO.

The 055 Series is designed for use with highly aggressive fluids. It shields internal components from chemical attack through a 100% PTFE fluidic path. The valves also feature low-wattage solenoid coils with minimal heat generation and thermal transfer to protect valuable samples and reagents.

Compared to competitive products, the new 055 Series PTFE valves address a wider range of market and OEM needs in terms of orifice sizes and flow rates. The valves are available in 2-way normally closed, 2-way normally open, and 3-way universal versions, and come with #10-32, 1/4-28, or 1/8 NPSC in-line porting for exceptional versatility. They are manufactured in ASCO's Class 8 clean rooms to eliminate contamination.

The isolation valves have excellent self-draining capability and an easy-to-flush low-volume internal cavity. They have superior vacuum and pressure ratings and are available in custom designs for specialized applications.

"ASCO 055 Series valves are supported by the company's AMT team, the industry's only group of engineering and application specialists dedicated to serving the analytical and medical industries," said Kemple.

The valves can be ordered as part of the company's Rapid Engineered Solutions Program, which cuts the lead times for customized valve and manifold assemblies by up to 50% for the analytical and medical instrument markets.
