Manage and Control Micro Flows.

Experience a total freedom on changing parameters with the best precision in automation.

Gas Blender


The MCQ GB100 Series is a compact Gas Mixer specifically designed for laboratories by MCQ Instruments. A powerful tool for managing and controlling MICRO FLOWS in gas mixing and gas dilution processes. Easy to install, to set, and to use, it is the fastest instrument on the market.

Gas Mixers vs. Mass Flow Controllers: LEARN THE DIFFERENCES

Our Gas Mixers


e.g. Considering a flow range of 0-500 mL/min, the instrument starts to work properly from 0,1 mL/min


e.g. If you need a flow of 100 mL/min you are free to modify and change the new values on a micro-scale of 0,01 mL/min, for example 99.99 mL/min with stable results.


Our instruments have such an incredibly stable control even on micro-values, that you can use them to create high dilution up to a scale of 1:1000

18 Calibration-Points

Our instruments calibration consists in a high-quality control process, setting a Calibration Curve on 18 calibration-points, each one measured and repeated for 6 times. We made everything to guarantee you precision and accuracy!

Traditional MFC


e.g. Considering a flow range of 0-500 mL/min, the instrument starts to work properly from 50 mL/min


e.g. First, consider the Cut-Off that makes difficult to any MFC to regulate flows under a certain value.
Second, if you set the flow at 100 mL/min you can modify values only on a scale of 1 mL/min, so if for example you need a flow of 99,50 mL/min the MFC will wobble between 99 mL/min and 100 mL/min with unstable results.


A great instability with low-flow does not allow to manage and create high dilution with precision.

5 Calibration-Points

Regular Mass Flow Controllers are calibrated based on a Calibration Curve of only 5 calibration-points.

• All the MCQ Instruments are a whole lab in single boxes ready-to-use. The traditional MFCs need instead of a tube system, external power supply and a large amount of space and budget to consider after.

• All the MCQ Instruments are shipped with a bundled Software (.FREE Version) for full automation. The traditional MFCs need instead of a manual approach.

• All the MCQ Instruments have been created to control every single parameter up to the whole management of every aspect of a gas mixture. The traditional MFCs were created instead to control only a single source of gas.

MCQ Gas Blender 100 Series is shipped with our Mixture Creator Software that allows to manage the mixing process by intervening directly on the single channel to modify and control the final blending or the final dynamic dilution. It also allows the management of each channel to define the input gas type provided from your own cylinder.



MCQ Gas Blender 100 Series is easy to install and use. You will only need a laptop or a desktop computer to connect the instrument via a simple USB connection. An easy push-in tube fittings system will allow you to connect your cylinders to the instrument and the output to lead your final mixture into your system.
