BVV Iso-Butane R600A: Instrument-Grade Isobutane in Bulk
Best Value Vacs sources and refines this isobutane in the USA and guarantees purity of at least 99.5%. Lot analysis puts isobutane above 99.8%, with n-butane under 2,000 ppm and propane under 250 ppm. Methane and ethane each read below 1 ppm, and sulfur comes back non-detected. Water, oxygen and nitrogen are held to single or low double-digit ppm levels. BVV calls it instrument grade, and it is sold for professional hydrocarbon extraction. Lower contaminant levels mean fewer unknown oils left in the finished extract. No ethyl mercaptan odorant is added, so the gas is clean, colorless and odorless. The liquid weight in the tank is 20 lb. It ships in a refillable DOT LP tank without a dip tube. Isobutane carries the formula C4H10, a molecular weight of 58.12 g/mol and CAS number 75-28-5. Its boiling point is 10°F, or -12°C. For transport it is classed as UN 1969, Isobutane, liquefied, hazard class 2.1.
Handling and Storing an Isobutane Solvent Safely
Isobutane is an extremely flammable gas held under pressure, and a heated tank may explode. Use it only in well-ventilated areas built for flammable gas work. Keep every ignition source away, including pilot lights, sparks, static and open flame. BVV recommends distilling every solvent before use. Store the tank upright and secured in a cool, ventilated spot out of direct sun. Keep the valve closed and capped whenever the tank is not connected. Check fittings for leaks with a gas-rated leak detector before each session. Wear eye protection and gloves when connecting or disconnecting lines. The product is intended for legal use only, in line with local laws and ordinances. Some states restrict sales of unodorized butane, and California limits retail sales to licensed processors and resellers. Keep the safety data sheet on hand wherever the tank is stored. Have the empty tank refilled or requalified through a qualified LP or gas supplier.
