The MCQ Gas Blender 4000 is an automated Gas Mixer created for laboratories, designed to generate, manage, and monitor gas mixtures with standard flow rates of non-corrosive, pure gases.


It offers an ideal replacement for pre-mixed gas cylinders, which are not only expensive and space-consuming, but also create significant logistical challenges in terms of delivery, storage, and workflow organization. At the same time, it provides a modern alternative to multi-channel mass flow controllers, which are typically inaccurate and slow when dealing with low and steady flows. We refer to our gas mixer as a true “Lab in a Box.”
Operate using percentages of gas, not just in flow rates
Complete and Ready-to-use System
Superior alternative to Pre-Mixed gas cylinders

MCQ Instruments provides bundled software with all of its devices for full automation. Our instruments are designed to control every parameter, from the individual components of a gas mixture to the management of the entire process.

Create Custom Gas Mixtures starting from Pure Gas
No specific skills are required. Easy to use and fully automated


Easy blending of gases, runs without user input (Programmable sequences).

The immediate availability of any gas mixture required (5% CO2, 0-18% O2) is a potentially substantial time saving feature, as ordering custom gas mixtures can take 1 month.

Running experiments is easy and straightforward.
