Independent Specialty Gas Producer for Custom Gas & Liquid Calibration Standards

Piston Standards

Constant Pressure Cylinders

Many applications require mixtures containing low vapor pressure and liquid components.
These may be components that are in the liquid phase at normal atmospheric temperatures
and pressures, or they may be components that are in the liquid state at the concentration and pressure desired in the container. These mixtures are made completely in the liquid phase using a floating piston cylinder (Constant Pressure Cylinder) to preserve mixture integrity. These are necessary especially when mixture components possess significantly different vapor pressures and solubility characteristics. In other words, these cylinders help light gases stay mixed with liquefied gases and are necessary for certain analytical methods.

CSI Gas can manufacture method based or custom liquid mixtures in a constant pressure cylinder for your specific application. We offer many different sizes and models by several different piston cylinder manufactures.
