Vacuum Pin Tube is an important laboratory apparatus which is used for collecting material in experiments such as hydrogen analysis and the like. This apparatus is also known as evacuated pin tube. Typically, its structure resembles to that of a glass dropper which is also a commonly used apparatus in laboratories. Vacuum Pin Tube is fabricated by using borosilicate glass with a wall thickness of approximately 0.5mm. The ends of this tube are permanently sealed.
Using The Vacuum Pin Tube
Vacuum Pin Tube consists of a bulb section whose wall is approximately 1 mm in thickness. When molten samples of gold, silver, etc, are bought close to bulb section, it melts and allows the molten material to enter the tube. A slag-free solid pin is formed by this process.
Simple spring holder is used for holding the Vacuum Pin Tube while it is in use. This tube is precisely inserted in the molten material at an angle of 45°. Slanting the tube is the most crucial part of this procedure and it must be done carefully.
Vacuum Pin Tube is easily available in different volumetric capacities. Certain specially designed types of Vacuum Pin Tubes are available for sectioning one gram to half gram of molten metal sample. Likewise, simply constructed Vacuum Pin Tube is generally used for rapid sampling few types of molten materials. On the whole, this laboratory apparatus may be very simple in design and structure but is extremely useful for a number of applications.
