"Four‑Layer‑Defense" Intelligent Gas Supply System Sets New Benchmark for Laboratory Gas Safety
Recap of VIGOUR's Keynote Speech: Safety Solution for Hazardous Gases in University Laboratories
On August 26, 2026, the Laboratory Safety & Smart Laboratory Technical Exchange Salon, hosted by Shanghai Laboratory Association, was successfully held. As a premium supplier of intelligent fluid control systems with long‑term expertise in fluid handling, VIGOUR was invited to attend. Ms. Cao Yuna, Sales Manager, delivered a keynote speech titled Safety Solution for Hazardous Gases in University Laboratories. Centered on the core topic of laboratory piping‑valve gas‑circuit safety, she systematically presented VIGOUR's Four‑Layer‑Defense Intelligent Gas‑Supply Safety System. This end‑to‑end solution covers top‑level design through on‑site implementation for university laboratory safety management, earning positive feedback from attendees.

Data Insight: Hidden Risks Behind 38% of Safety Incidents
At the opening of her speech, Ms. Cao cited alarming statistics: according to incomplete statistics, roughly 38% of safety accidents in China's university laboratories over the past five years are directly gas‑related, with more than 120 gas‑involved incidents publicly reported.
Invisible and intangible, hazardous gases pose high risks across storage, transmission, usage and management links: unsecured gas cylinders, improper co‑storage of flammable‑explosive and oxidizing gases, loose compression fittings, cumulative micro‑leaks, uncontrolled terminal pressure, lack of intelligent monitoring data, and more. Negligence at any point may lead to catastrophic consequences.

Meanwhile, national and industrial standards covering laboratory safety, fire‑protection in building design, cylinder safety and university laboratory specifications have come into force. Laboratory gas systems are now required to be traceable, monitorable and zero‑tolerant to failures. As a co‑developer of group standard T/SLEA 0071‑2023 Technical Specification for Gas‑Supply Valves and Accessories for Laboratories, VIGOUR fully recognizes this compliance imperative: safety is not optional‑‑it is mandatory.

Four‑Layer‑Defense: Full‑Link Safety Closed‑Loop from Gas Source to Intelligence
Addressing these pain points, Ms. Cao introduced VIGOUR's four‑layer‑defense safety system for hazardous laboratory gases, with multi‑level interlocking safeguards:

▌Layer 1 - Gas Source Level
The GC‑Series Specialty Gas Cabinets and automatic switch‑over panels enable isolated cylinder storage, mechanical ventilation and nitrogen purging. PLC‑based intelligent control realizes automatic switch‑over between primary and backup cylinders for non‑stop gas supply. Real‑time monitoring and interlocked alarms cover pressure, temperature, leakage and residual gas volume. Remote monitoring and SCADA system integration support unattended operation.
▌Layer 2 - Transmission Level
316L EP tubing and VCR metal‑face‑seal joints establish polymer‑free gas flow paths. Combined with automatic orbital welding, the overall leak rate reaches ≤ 1×10⁻⁹ mbar·L/s, inner surface roughness Ra < 8 μin (EP grade), cleanliness ISO Class 5, eliminating gradual micro‑leak accumulation at source.



▌Layer 3 - Terminal Level
VSR‑Series high‑purity pressure regulators (max. inlet pressure 100 bar, Hastelloy C276 diaphragm, PCTFE/PEEK seat, external helium leak rate 1×10⁻⁸ mbar·L/s) paired with VFB200 flashback arrestors deliver triple protection: pressure stabilization, flashback prevention and emergency shut‑off, preventing out‑of‑control conditions at end‑use points.


▌Layer 4 - Intelligent Management Level
The VGDS Gas Box integrates valves, filtration and pressure regulation. Built upon customer‑specific PID 3D modeling and 1:1 prefabrication, the modular design cuts footprint by over 50%. Full‑parameter SCADA integration transforms safety management from manual patrols to data‑driven visibility and traceable incident records.
These interlocking four layers underpin VIGOUR's robust commitment for laboratory gas systems: overall leak rate ≤ 1×10⁻⁹ mbar·L/s, particle count ≤ 1 particle per cubic inch.

VIGOUR - Surface Finish: Magnifier for Material Purity
Material purity directly determines surface‑treatment performance. Even for electropolishing (EP), regular 316L and VIM‑VAR remelted 316L yield distinctly different surface roughness:
Regular 316L after EP: Ra ≈ 10‑25 μin (0.25‑0.63 μm)
Remelted 316L after EP: Ra down to 5 μin (0.13 μm)
Smoother surfaces generate fewer particulates during gas flow and reduce micro‑crevices that trap contaminants. In semiconductor manufacturing, a single particle can cause wafer rejection - this is why UHP systems demand remelted base materials.

Rigorous Validation: Five‑Fold Testing & Authoritative Certifications for Quantifiable, Traceable Safety
Safety is not a slogan, but an verifiable engineering commitment. According to Ms. Cao, every VIGOUR product undergoes 100% five‑fold stringent factory testing: pressure holding test, helium leak test, moisture test, oxygen content test and particle test.
24‑hour pressure holding at 1.2× rated pressure (ΔP < 0.5%)
Helium leak detection down to 1×10⁻⁹ mbar·L/s
Moisture & oxygen content returning to baseline within 4 hours
Particle count ≤ 1 particle per cubic inch (≥ 0.1 μm)
Fully traceable test reports are issued for each unit; third‑party helium‑leak inspection reports are available upon request.

For manufacturing, VIGOUR adopts 316L VIM‑VAR ultra‑high‑purity raw materials. Automatic orbital welding is performed in ISO‑Class‑5 clean‑rooms under 99.99999% purified argon shielding, with 100% weld inspection. Electropolishing and passivation deliver smooth, corrosion‑resistant inner wetted surfaces.
The product portfolio is backed by over ten authoritative certifications including CE, BAM, ATEX, ISO 9001, ISO 14001, SEMI F1/F106 and RoHS, plus salt‑spray qualification. As a council member unit of Shanghai Laboratory Equipment Association, VIGOUR participates in industrial‑standard development, building a complete quality barrier covering materials, processing and certification.

Proven Practice: Mature Solutions Validated Across Four Application Scenarios
Real‑world projects prove solution performance. Ms. Cao shared four university‑laboratory field references:
Synchronized management of dozens of gas circuits for university chemistry labs, covering inorganic, organic, analytical and physical‑chemistry workflows.
Safe delivery of corrosive gases for marine‑energy, environmental and biological‑resource research in university marine‑science projects.
GC carrier‑gas control with 0.1 psi‑level fine pressure adjustment for mass‑spectrometer matching.
Bioreactor mixed‑gas supply with multi‑channel O₂/CO₂ blending accuracy of 0.1%, validated for high‑temperature steam sterilization.

From fundamental chemistry to cutting‑edge research, VIGOUR solutions have passed real‑world validation at multiple universities.
Laboratory safety leaves no room for negligence; gas management tolerates zero errors. As a trusted supplier of intelligent fluid‑control systems, VIGOUR will keep leveraging its Four‑Layer‑Defense safety framework and robust manufacturing capabilities to safeguard gas‑system safety in laboratories, laying a solid safety foundation for university scientific research.
