LB 165 Single-Stage Stainless Steel Lecture Bottle Regulator

These type 316 stainless steel single stage regulators are recommended for high purity, corrosion resistant / toxic gas applications where slight variance in delivery pressure is acceptable as tank pressure decays. The materials of construction will not contaminate the gas stream, and the regulators are highly resistant to inboard diffusion of atmospheric contaminants. A stainless steel needle valve is installed in the outlet.

These regulators are highly recommended for control of the pure gases and mixtures used in the semiconductor industry, as well as for moisture analysis, trace hydro-carbon analysis, air pollution and auto emission analysis, and a variety of other critical laboratory techniques. They are able to withstand the internal vacuums generated during purging operations. Each regulator features a vented housing cap to remotely vent process gases.
