 Several methods of glass tube cutting

Thermal truncation is often used to truncate glass tubes above 12 mm. There are several methods as follows: (1) Hot spot method: take an iron wire, sharpen one end, and install a wooden handle on the other end. Put the tip of the iron wire on the alcohol lamp to burn red, place it on the notch of the glass tube, stay for a while, drop 1-2 drops of cold water, the notch will crack, and then put the red-burning iron wire on the front of the crack 1-2 At centimeters, the crack will extend forward, and the operation will be repeated until the glass tube breaks. You can also take a glass rod, heat it, pull it into two, continue to heat the thin end of one of them until it becomes a white-hot bead, and quickly press it against the notch of the glass tube (the glass tube is etched). Moisten the scar with water in advance, without leaving water droplets.) A circle of flat cracks appeared on the glass tube immediately, and the glass tube was disconnected by gently breaking it. (2) Flame cutting: Use the tip of the flame of the blowtorch to heat the notch of the glass tube, and keep turning the glass tube. When the glass tube is slightly red, remove the flame, and quickly blow air at the notch with the sharp nozzle. Or use a wet brush to apply a circle of cold water around the score to make it cool rapidly, and the glass tube will be disconnected from the score.
