This isn't your typical school lab Bunsen burner - this universal propane burner takes things to the next level! The head rotates a full 360 degrees and locks at any angle, which is super handy for jewelry making, glass work, or any project where you need to heat something from a specific angle. The height adjusts from 7 to 9.8 inches too, giving you even more control. But the coolest part? You can adjust both the size AND shape of the flame! Unlike traditional burners that just change the size, this one lets you create different flame styles for different tasks. It's made from solid brass that can handle high temperatures without burning up, even during extended use. The 13.7 inch hose keeps the propane tank safely away from the work area, and it works with standard 8.1-16 oz disposable propane tanks (the kind used for camping). Whether you're in a professional lab, working on jewelry, doing glass blowing, or just need a reliable heat source for various projects, this adjustable burner gives you the precision and versatility you need. It's basically several tools in one - way more flexible than old-school Bunsen burners!
