Customized CH4 Gas Cylinders 50L

Pricing for 50L specialty gas cylinders, including CH4 and other gases, varies based on concentration level, gas mixture complexity, and cylinder type selected. SpecGas provides custom pricing upon request. Factors influencing cost include PPM or PPB concentration range, balance gas selection, and cylinder material (aluminum, steel, or nickel-plated). Contact SpecGas for a tailored quote.

Type 3 cylinders feature a metal liner (typically aluminum or steel) fully wrapped in composite fiber, offering a balance of strength and reduced weight. Type 4 cylinders use a polymer plastic liner fully wrapped in composite fiber, making them the lightest option and ideal for high-pressure applications. SpecGas offers disposable and refillable aluminum and steel cylinder options suited for calibration gas use.

SpecGas produces methane (CH4) gas blends across a wide range of concentrations, from PPB (sub-ppm) levels up through low PPM (1–100 ppm) and custom-specified ranges. Balance gases available include nitrogen, zero air, and inert gases. Custom concentrations can be blended to exact customer specifications for calibration, research, or process monitoring applications.

Yes. All methane calibration gas standards produced by SpecGas Inc. are NIST traceable, meaning they are manufactured and verified against National Institute of Standards and Technology reference standards. This ensures measurement accuracy and regulatory compliance for gas detector calibration, emissions monitoring, laboratory research, and quality control processes that require certified reference materials.

Customized CH4 cylinders are used across several industries including environmental and air quality monitoring, electronics and semiconductor manufacturing, university and independent research laboratories, industrial process control, and oil and gas operations. They are essential for calibrating gas chromatography equipment, LEL and hydrocarbon gas detectors, and emissions monitoring instruments across these sectors.

The SpecGas Stability Guarantee is a proprietary commitment backed by a unique internal cylinder treatment process developed by founder Alfred Boehm. It ensures that reactive gas mixtures, including low-ppm CH4 blends, remain chemically stable within specification for their full stated shelf life. If a customer disputes the results, SpecGas provides a replacement mixture immediately and conducts a re-analysis of the original.
