1、 Application in core experimental scenarios

Combustion and Thermodynamics Experiment

Combustion efficiency testing: In engine fuel combustion analysis, it is necessary to strictly control the oxygen concentration to simulate different air-fuel ratio conditions.G190The series can be adjusted by adjusting the output pressure（0-10bar）Accurately control the oxygen flow rate and fine tune it with the flow meter to ensure the reproducibility of the experiment.

Thermogravimetric analysis（TGA）In material thermal stability testing, oxygen as a reactive gas needs to be supplied stably. The single-stage pressure reducing structure of the pressure reducer can avoid the influence of pressure fluctuations on experimental data and improve the accuracy of the results.

Catalyst activity evaluation

Oxidation reaction research: In catalyst performance testing, oxygen pressure directly affects the reaction rate.G190The series can be paired with a mass flow controller to provide stable low-pressure oxygen for fixed bed reactors (such as...)0.5-2bar）Meet the requirements of microreactors or high-throughput screening.

In situ characterization experiment: inXX-ray absorption spectroscopy（XAS）In Raman spectroscopy combined systems, the pressure regulator needs to adapt to narrow spaces. Its lightweight design (only)0.90kg）It can be flexibly installed on the experimental bench to reduce interference with the optical path.

Biology and Medicine Laboratory

Cell metabolism research: In a closed oxygen controlled incubator,G190The series can provide low concentration oxygen to cells (such as...)5% O₂）Simulate a hypoxic environment. Its built-in safety valve can prevent overpressure from causing gasification of the culture medium, ensuring experimental safety.

Animal respiration experiment: In rodent metabolic cages, the pressure reducer needs to be paired with an anesthesia machine or ventilator to provide stable oxygen output. its2″The pressure gauge can display pressure in real time, making it easy for experimenters to quickly adjust parameters.

2、 Technical adaptability: dual guarantee of precision and stability

Pressure control accuracy

G190The series adopts a single-stage pressure reducing valve core, with a pressure fluctuation range of less than±0.5barIt can meet the high requirements for gas purity in experiments such as chromatographic analysis and mass spectrometry. For example, in gas chromatography（GC）Stable carrier gas (oxygen) pressure can avoid baseline drift and improve detection sensitivity.

Compatibility and Scalability

Interface adaptation: SupportsCGA540Standard oxygen interface, which can seamlessly integrate with the existing gas system in the laboratory.

Modular design: The output end of the pressure regulator can be equipped with pressure sensors or flow meters to achieve real-time data collection and automated control.

Security protection design

Built in filter: The sintered bronze filter can intercept particles in the gas path, preventing contamination of experimental samples or damage to precision instruments (such as atomizers in atomic absorption spectrometers).

ULCertification Guarantee: Passed through the United StatesULSafety standard certification, meeting the laboratory's requirements for explosion prevention and electrical safety, reducing the risk of fire or explosion.

3、 Operational advantage: Convenient and efficient experimental experience

Portability and Space Optimization

G190Series compact appearance（130mm×120mm×70mm）It can be easily placed in the corner of a fume hood or laboratory bench, saving laboratory space. Its lightweight design（0.90kg）Easy for experimenters to move or adjust their position.

Quick response and maintenance

Convenient pressure regulation: The knob type pressure regulation structure supports one handed operation, which can quickly adjust the oxygen pressure during the experiment and adapt to dynamic experimental conditions (such as temperature gradient experiments).

Low maintenance cost: Three years of free repair service and modular component design, reducing downtime and lowering laboratory operating costs.

4、 Conclusion

G190The series of lightweight oxygen pressure reducers are an ideal choice for laboratory oxygen supply due to their precise pressure control, high safety, and portable design. Its application scenarios cover multiple fields such as combustion analysis, catalyst research, and biomedical research, making it particularly suitable for experimental environments with high requirements for gas stability, space utilization, and operational convenience.
