Blowpipes
These are very similar to what early chemists and mineralogists used for blow pipe analysis of minerals. Consult a suitable text (Brush & Penfield, O.C. Smith, etc.) for details of how this procedure was done. Even the Chemcraft manuals detailed some experiments with the blowpipe; five or six decades ago, before instrumental analysis became commonplace, the old-time technique was discussed in nearly every chemistry and mineralogy text.
Blow pipe: nickel-plated brass, 8" long.......................................$2.79 each
Ship wt. approx. 0.1 lb each.
Wear safety goggles and gloves when using the blowpipe. Never inhale back through a blowpipe when you have it up to a flame. You must use the nose to breathe in and use the blowpipe only for exhalation, otherwise you could inhale poisonous and/or hot gases. It is recommended to use a small, low-powered air pump (e.g., an aquarium pump) to provide air for the blowpipe, rather than using your mouth. Also please remember that this item is made of metal; it can therefore become hot (to use it properly, you don't actually need to touch the flame with it). You alone are responsible for the safe & proper use of this item. By placing an order, you signify agreement to our Terms of Sale / Terms of Use.
