Tool Free, Leak Free - Micro-QT™

The Micro-QT is a next generation gas valve offering uncompromising leak-tight performance in an ergonomic design. The Micro-QT is also versatile, providing numerous connection options to cover a wide range of applications. Once the valve is connected to tubing using compression fittings, mating male and female valve ends is literally just a quick “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 distinctive bright and colorful Silonite 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.

Designed specifically for tool-free air sampling and hassle-free analysis.

The Most Durable and Accurate Sample Collection Valves for EPA Methods TO-14A and TO-15.
There are several ways to fill a Micro-QT™ canister or Bottle-Vac™.
Grab Sampling
MiniCan™ or Bottle-Vac™ samplers are filled within 0.1–0.3 minutes using an unrestricted sampler with a Micro-QT™ valve.
Restricted Critical Orifice Sampling
Sample collected using a filtered orifice restricted sampler. Fill rates are constant until the canister reaches ½ atmosphere.
Time Integrated Sampling
Time-integrated sampling is used for slow filling of canisters to determine average target compound concentrations. Fill times are 10–50 times longer than with critical orifice restricted samplers. Use CS1200E and the PN: 30-22800 adapter for Micro-QT™ Valve Samplers.
