Silonite Low-Profile Male Micro-QT Valve

The MQT-ST400S is a shortened SiloniteTM Male Micro-QTTM Valve with tube connection. It can be utilized along with the Entech TrueSeal valve to enable tool-free operation or auto-sampler compatibility of classical sampling canisters such as the 2.7L, 3.2L, or 6L canisters.  See complete applications list below.  For the uncoated equivalent of this valve simply remove the “S” from the part number.

Product Description

The Micro-QT is a next generation gas valve offering uncompromised leak-tight performance in an ergonomic design. The Micro-QT is also versatile, providing numerous connection options to cover a wide range of applications. After the Micro-QT valve is installed on tubing with a compression fitting, mating male and female valve ends is literally just a “snap”.

Originally designed for environmental air sampling and analysis, the Micro-QT has found a place in numerous other applications. Micro-QT’s feature a distinctively bright and colorful SiloniteTM coating that prevents gas phase compounds from interacting with the metal surface. The rugged, solid design stands up to thousands of connections while maintaining leak-tight operation. For scientists and professionals working with VOC and SVOCs, the Micro-QT’s compact internal volume reduces exposure to potentially contaminated surfaces and allows for easy cleaning.
