The laboratory requires a constant carrier gas flow rate and high gas purity, providing stable gas with stable values and pressures for the analysis equipment selected by the laboratory. Establishing a centralized gas cylinder room can save limited laboratory space, and there is no need to cut off gas when replacing gas cylinders to ensure continuous gas supply. Users only need to manage fewer cylinders and pay less cylinder rent, as all points of use using the same gas come from the same gas source. This supply mode will ultimately reduce transportation costs, reduce the amount of gas remaining in empty bottles, and ensure good cylinder management. The centralized pipeline supply system can set up air outlets at the point of use, making the workplace design more reasonable and ensuring the safety of storage and use. Ensure that analysis and testing personnel are protected from the influence of toxic and harmful gases during experiments.
