The Model 3810 Series has been improved to meet the demands of the gas chromatographer. The Model 3810 Series has been long established as a standard in the laboratory and processing facilities as a high purity corrosion resistant product. The dual stage design of the product ensures accurately delivered pressures over the usable life of gases in cylinders.
The Model 3810 Series regulators are recommended for use in applications requiring high purity delivery of gases in a non-corrosive or semi-corrosive environment at a constant outlet pressure. These applications typically include use of the regulators for analysis of samples, calibration standards, semiconductor applications and doping applications. The Model 3810 Series is compatible with gases that are non-corrosive or semi-corrosive in nature and gases that are compatible with the materials in the process stream.
