DescriptionThe Model 3120 Series is a new product being offered for use on Gas Chromatographs and other scientific instruments. The Model 3120 Series regulators have been designed with a reduction in the internal dead space of the regulator and a reduction in the quantity of non-metal parts. The dual stage design of the product ensures accurately delivered pressures over the usable life of cylinder gases.
The Model 3120 Series regulators are recommended for use in applications requiring high purity delivery of gases in a non-corrosive environment. These applications typically include use of the regulators for high purity carrier gases, calibration standards and GC applications using PID, HID or ECD detection methods. The reduced dead space of the regulator and the reduction in non-metal parts ensures high purity control of gases. The Model 3120 Series is compatible with gases that are non-corrosive in nature and gases that are compatible with the materials in the process stream.
