Eisco Scientific No Tip Bunsen Burner,Iron,LP Fuel

Just hooked up to small disposable propane tank for science project and works great.Fine needle adjustment is a nice plus. Nice wide balanced base, very stable. Would buy again

Excellent product! Works great in my mineral testing lab. Already making me money!

The needle valve isn't held captive, which means if you open it too much the entire thing comes out. It should be obvious, but this can be very dangerous if the burner is lit when it happens. Also, the air adjustment is very loose and needs be readjusted every time the burner is moved, as the slightest vibration causes it to rotate.

this burner is just what I wanted it is easy to adjust and the large base makes it stable.

Good: Sturdy Nice flame Can adjust to low or high Bad: The collar was loose, so it can slip side to side and change your settings. Arrived a little rusty

Operation satisfactory. Burner was in a transparent plastic sack - no box, paperwork or any written instructions. Operating manual or even PDF would be helpful (not available at online vendors or through manufacturer). Would like statement in a written specifications as to what is the minimum propane pressure required for optimal functioning. Also, casted ribbed fuel input tube was very difficult to tighten an 8 mm gas source tubing even with the clamp provided with the tubing. Again, an operating manual would be helpful. Thanks.

Works as it should. Use it in the science lab at school. I am happy with it. :)

Good but not steady
