Reliable sample containment for natural gas and light liquid hydrocarbon analysis
The Welker SC Single Cavity Cylinder is a DOT 3E sample cylinder designed for the collection and transport of natural gas samples from the field to the lab. Built from seamless 316L stainless steel, the double-ended SC Cylinder helps minimize corrosion, absorption, adsorption, and chemical reactivity for more reliable sample integrity. With smooth wall-to-neck transitions, Welker instrument valves and reliefs, optional Chembar™ or Sulfinert® treatment, optional outage tube, and optional foam-lined carrying case, the SC Cylinder supports spot or composite sampling of natural gas and light liquid hydrocarbons in demanding field applications.
Natural Gas Sample Collection and Transport
Spot or composite sampling applications that require a durable single cavity cylinder to collect and transport natural gas samples from the field to the lab
Light Liquid Hydrocarbon Sampling
Spot or composite sampling of light liquid hydrocarbons when the cylinder is equipped with an outage tube to provide vapor space
Laboratory Sample Analysis
Field-to-lab sample containment for operators who need reliable sample integrity before analysis
Complies With:
DOT 3E Compliance
Supports safe transport of sample cylinders to and from off-site laboratories.
Welker Instrument Valves and Reliefs
Provides precise flow control and overpressure protection during sample collection, transport, and handling.
Seamless 316L Stainless Steel Construction
Helps minimize corrosion, absorption, adsorption, and chemical reactivity while eliminating vulnerable welds.
Smooth Wall-to-Neck Transitions
Helps prevent trapped fluids that could skew analysis and makes the cylinder easier to clean between samples.
Optional Chembar™ or Sulfinert® Treatment
Protects sample-exposed parts against sulfur absorption and corrosion in sour gas or reactive sample applications.
Optional Outage Tube
Provides the required vapor space for light liquid hydrocarbon sampling.
Optional Foam-Lined Carrying Case
Helps stabilize and protect the cylinder during transport, shipping, and field handling.
