Pure Products
Industrial Source produces, purifies and packages high purity hydrocarbon gases. Our products are refined, distilled and designed specifically for critical applications that require guaranteed purity. Our goal is long term sustainability, developing specialty products with regulations and compliance in mind. We utilize our expertise in a wide variety of specialty applications to engineer products that maximize results and yields. Trust the experts: see our FAQ’s below.
Extraction Solvents (Non-Odorized)
Industrial Source distributes from three 12,000 gallon extraction-grade bulk tanks in Springfield, Oregon. Our local, abundant supply ensures your business will not be disrupted by product delivery delays. N-Butane, Isobutane, and N-Propane are available on-demand and we provide a quick turnaround on custom mixes.
- Highest purity products available
- Solvents are pre distilled & ready for use
- Dedicated lines, filters, pumps & hoses
- We do not salvage residual product
- Specialized processes in place to ensure purity & eliminate potential contaminants
- State-of-the-art onsite laboratory
Process Controls/Quality Standards
Industrial Source follows a specialized process to maintain purity from start to finish. Prior to filling, each cylinder is subjected to a proprietary cleaning process which eliminates particulates, residual oils, weld slag, metal shavings, and mill scale present from the cylinder manufacturing process.
- Competitor Top Filling Refill Procedures: Filling gas product on top of residual gas & unknown contaminants.
- Industrial Source Refill Procedures: Evacuation (residual product removed), Inspection (internal wash if necessary), Vacuum (remove air and moisture), Fill (max allowed by D.O.T.), Analysis (certified product-COC).
- Examples of residual oils / unknown contaminants. *Note a passive distillation may remove some solids but will not remove contaminants with similar chemical composition (ex. Benzene, Hexane).
Specialty Valving Procedures
Industrial Source implements specialty valving procedures to minimize contamination. Each time a cylinder is de-valved/re-valved, it can jeopardize the integrity of the valve threads and introduce metal and debris into the cylinder. Valving is an abrasive process and multiple de-vales and re-valves should be avoided.
Cylinder/Valve Preparation
Shown in the table to the right are the metals/contaminants introduced during the industrial valving process.
Analysis/Traceability
Industrial Source utilizes a dedicated cylinder fleet for high purity solvents. This eliminates cross contamination and unknown impurities that can be introduced from different industrial applications.
Industrial Source's on-site laboratory uses FID (flame ionization detector) to certify product at parts per million (PPM). Cylinders are tested after fill to ensure quality. Certificate of Conformance (COC) lists your cylinders' serial numbers, ensuring your products meet purity standards. We reference not only the source material, but what's in your cylinder. Analysis = traceability.
Certifications and Analysis
Analysis after each step to ensure purity and maintain quality. Cylinder serial # listed on Certificate of Analysis (COA).

Frequently Asked Questions:
Q: Is there such a thing as Food Grade/Medical Grade butane?
A: There is no food grade or medical grade butane (just deceptive marketing). The industry standard for extraction solvents is 99.5%+ non odorized products. It important to have a complete analysis (COA) at PPM certifying the products purity and listing any impurities. *Be on the look out for benzene and hexane as they are toxic for consumption.
Q: What is top filling a cylinder?
A: Top filling is refilling a cylinder that has not been evacuated, and put under vacuum. Instead, gas product is filled right on top of the residual product and unknown contaminants. This is common among industrial gas filling operations. Top filling into cylinders leads to inconsistent purities, uneven mix ratios and unknown contaminants.
Q: What is causes black flakes/particulate in my cylinder?
A: This particulate is left over from the cylinders manufacturing process. All carbon steel cylinders rust over time and is accelerated in the presents of moisture. These solvents do their job and will dissolve any non-volatile residue (rust) from the cylinder wall. An internal wash can minimize this, along with an in-line micron filter.
Q: Why is purity important?
A: The higher purity the gas/solvent, the more consistent product. Meeting higher purities like 99.5%+ requires the removal of impurities and contaminants. Lower purity products vary in purity and can have higher amounts of harmful contaminants ( ex. BTEX, C6+, Hexane, Alcohols & Acetone).
Q: Do I need to distill my products?
A: Industrial Source products are pre distilled and ready for use. The term “distillation” in the extraction community is more of a “passive distillation” which is filtration. This may remove some solids/particulate, but will not eliminate contaminants with a similar chemical composition (ex. Benzene). Save downtime with Industrial Source’s guaranteed pure products.
