Marquest Scientific

Family owned and operated since 1979, Marquest Scientific’s roots in ThermoPlastic injection molding of corrosion resistant and high purity plastics began in the late 1950s, when our founder brought over the first reciprocating screw type injection molding machine to the USA from Ankerwerk, a company based out of Nurnberg, Germany. It was this machine that solved the problem of molding highly rigid PVC industrial parts and gave our founder the confidence to mold the industrys first all plastic ball valve in 1964. This spirit of innovation and expertise is what drives our company today. Our RedBook quality program provides both daily and weekly product evaluations to ensure that our product evolves and is currently meeting the most demanding industry applications. A sample of some of our industry leading products include: Throttle Master™ Needle Valves, Tuff Guard™ Gauge Isolators, and the Series LG/LT Laboratory Fixture line, available in PVC, CPVC, Polypro, & PVDF. As a compliment to our proprietary product offering, Marquest provides Custom Product Development and Manufacturing for a number of well known, leading companies in our industry.
