All mixed and specialty gas cylinders sold by Gas Cylinder Source are manufactured or recertified to current DOT standards and equipped with CGA-approved valves appropriate for the intended gas or gas mixture. These cylinders are designed to safely store gases such as argon-based blends, nitrogen mixes, specialty noble gases, calibration gases, and other application-specific mixtures, depending on configuration.
Gas Cylinder Source sells mixed and specialty gas cylinders outright, enabling laboratories, OEMs, universities, and industrial users to own their cylinders, eliminate recurring rental fees, and manage specialty gas refills locally through qualified suppliers. This ownership model is particularly valuable for operations with ongoing specialty gas needs, long project timelines, or decentralized facilities.
Mixed and specialty gases are often used in applications where gas composition, purity, and delivery compatibility are critical. Selecting the correct cylinder depends on gas type, mixture ratio, pressure rating, cylinder material, and valve specification. All cylinders ship empty for safety and regulatory compliance and must be filled by a qualified specialty gas provider familiar with the specific gas blend requirements.
CO2 / nitrogen mix cylinders for the perfect beverage pour. Also known as beer gas or G-mix, combined CO2 and nitrogen tanks deliver the correct gas for nitrogen-infused beers like Guinness and other stouts.
CO2 nitrogen mix cylinders are available in sizes from 20 cu ft to 60 cu ft to suit any beverage dispensing application.
FREQUENTLY ASKED QUESTIONS
What are mixed and specialty gas cylinders used for?
Mixed and specialty gas cylinders are used to store and supply specific gas blends or specialty gases for laboratory, industrial, and technical applications.
These gases are commonly used in calibration, research, electronics manufacturing, welding blends, and controlled process environments. The exact application depends on the gas composition and the required purity.
The cylinders in this category are designed to contain specialty gases that require precise handling, safety, and compatibility with the appropriate valve systems.
Do mixed and specialty gas cylinders ship full or empty?
All mixed and specialty gas cylinders ship empty.
Shipping filled specialty gas cylinders is restricted due to safety and regulatory requirements. Gas Cylinder Source ships cylinders empty so they can be transported legally and safely.
Customers must arrange filling with a qualified specialty gas supplier capable of handling the specific gas or gas mixture.
Are these cylinders DOT certified?
Yes, all mixed and specialty gas cylinders sold by Gas Cylinder Source meet current DOT certification requirements.
DOT certification ensures the cylinder complies with federal standards for pressure containment, construction, testing, and identification. This is required for legal transport and filling in the United States.
Cylinders are either newly manufactured or recently recertified, providing current test dates and dependable service life.
What types of gases can be used in these cylinders?
These cylinders can be used for a wide range of specialty gases and gas mixtures, depending on configuration and valve type.
Examples include argon-based blends, nitrogen mixtures, calibration gases, and other specialty or noble gases. Gas compatibility must be verified before filling.
The intended gas must match the cylinder’s certification, pressure rating, and valve specification.
What valve types are used on mixed and specialty gas cylinders?
Mixed and specialty gas cylinders use CGA-standard valves selected based on the specific gas or gas mixture.
Valve selection is critical to prevent cross-connection and ensure compatibility with regulators and delivery equipment. Different specialty gases require different CGA valve outlets.
Customers should confirm valve requirements with their gas supplier or application documentation before purchase.
How are mixed gas cylinders different from single-gas cylinders?
Mixed gas cylinders are intended to contain precise gas blends rather than a single pure gas.
The cylinder itself may be similar in construction, but labeling, valve selection, and filling procedures differ to support mixture accuracy and safety.
Specialty gas suppliers control blend ratios during filling, not the cylinder itself.
What sizes of mixed and specialty gas cylinders are available?
Mixed and specialty gas cylinders are available in a range of sizes, from smaller laboratory-scale cylinders to larger industrial-capacity tanks.
Smaller cylinders are often used for calibration and research, while larger cylinders support manufacturing and long-duration processes.
Size selection depends on consumption rate, storage constraints, and refill logistics.
How much pressure do mixed and specialty gas cylinders hold?
Pressure ratings vary based on cylinder specification and intended gas service.
The service pressure is permanently stamped on the cylinder and must be matched with appropriate regulators and filling equipment.
Specialty gases may have different pressure requirements than common industrial gases.
How often do mixed and specialty gas cylinders need to be recertified?
Recertification intervals for mixed and specialty gas cylinders are determined by DOT regulations based on cylinder type and specification.
The current test or requalification date is stamped on the cylinder shoulder. Cylinders that are out of test are not compliant and may be refused by specialty gas suppliers.
Regular recertification ensures the cylinder remains safe for continued high-pressure use.
Who should buy mixed and specialty gas cylinders from Gas Cylinder Source?
Mixed and specialty gas cylinders from Gas Cylinder Source are ideal for laboratories, universities, OEMs, manufacturers, and technical service providers.
They are well-suited for organizations that require compliant cylinders for specialty gas blends without long-term rental commitments.
Gas Cylinder Source supports both single-cylinder purchases and larger orders, making this category suitable for small research teams and large industrial operations alike.
