Pintube samplers are high temperature borosilicate glass tubes used to sample molten metal. They are the simplest way to attain a specified diameter pin for testing.
Using a pintube sampler is a quick simple process.
Simply immerse the pintube into the molten metal with the bubble down. In seconds the bubble will melt and the holder will jolt telling the sampler that the chamber is filled. Quickly dip the sample in a cool liquid and in moments the hardened pin is ready to be cracked away from the tubing.
