Gas Mixing Station with Multi Channel Float Flowmeters Gas Control System
Highly Economical Gas Mixing Station with Multi Channel Float Flowmeters Gas Control System – Mobile, electricity-free mixing cabinet designed for budget-conscious inert gas purging and atmosphere management.
The GYS-xF Series is a practical, CE-compliant gas mixing system engineered to deliver cost-effective and highly reliable flow control of inert gases. Operating on clean mechanical principles with an accuracy threshold of 4%, it requires absolutely no electrical power connection. It is available in modular 2, 3, or 4-channel configurations, with the entire gas manifold, mixing vessels, and high-purity piping integrated into a heavy-duty mobile cabinet with locking caster wheels.
Featuring highly readable mechanical glass flowmeters, fine-tuning needle control valves, and high-purity fluid pathways, this robust gas mixing station serves as the perfect companion system for tube furnaces, glove muffle enclosures, plasma cleaners, and basic CVD setups across UK institutions.

Gas Mixing Station with Multi Channel Float Flowmeters Gas Control System – GYS-xF Series
Benli Lab is the Exclusive UK Distributor of Hefei Weiyuansu Laboratory Equipment. The GYS-xF series gas delivery system (featuring GYS-2F, GYS-3F, and GYS-4F builds) provides academic and industrial laboratories across the United Kingdom with a budget-friendly, highly robust gas-purging hub. By removing the electronic complexities of standard MFCs, this purely mechanical float-flow system operates entirely without electricity, eliminating risks of signal interference or power-drop interruptions. Outfitted with high-durability glass rotameters, an integrated stainless steel mixing tank, and smooth manual needle adjustment valves, it represents an incredibly stable baseline for managing inert atmospheres inside high-temperature muffle or tube furnaces.
Key Features & Benefits
- Purely Mechanical Flow Control – Requires no electrical power to operate, making it exceptionally safe, highly durable, and immune to power fluctuations or electrical line noise.
- High-Readability Rotameters – Clear glass float tubes provide instant, highly accurate volumetric feedback (4% accuracy) under low-pressure laboratory environments.
- Heavy-Duty Mobile Workspace – Integrated within a structural metal cart equipped with rolling casters and brake steps. The cabinet's robust top-plate serves as an excellent space-saving platform to hold your tube muffle furnace directly.
- Homogeneous Gas Mixing – Built with an internal, high-integrity stainless steel mixing vessel (Φ76 × 154 mm) connected to front-facing manual needle valves, assuring perfect gas homogenization before introduction to the process tube.
- Reliable Gas Seals & Fittings – Built with high-purity 6.35 mm (1/4 inch) PTFE and stainless steel plumbing paths coupled with reliable double-ferrule compression Swagelok-style connectors to prevent backflow and leaks.
- Flexible Multi-Channel Scale – Available in modular 2-channel (GYS-2F), 3-channel (GYS-3F), or 4-channel (GYS-4F) builds with customizable rotameter limits.
