Various Uses of Vacuum Pin Tubes

September, 13, 2013

Vacuum Pin Tube, also known as Evacuated Pin Tube, is used for collecting samples of molten material for the purpose of hydrogen analysis. Vacuum Pin Tubes are fabricated from borosilicate glass, and the wall thickness stays approximately 0.5 mm. Both the ends of the tube are sealed. The following section elaborates on how exactly the Vacuum Pin Tubes work.


How Do Vacuum Pin Tubes Work?

The characteristic feature of a Vacuum Pin Tube is the thin, approximately 1 mm., wall bulb section. When the tube is brought in contact with the molten sample such as gold, silver, steel, iron etc, the bulb melts and allows the fluid to enter into the tube. This results in the formation of a solid, slag-free pin.


The process described above involves the use of a simple spring holder that holds the Evacuated Pin Tube. It is the requirement of the process that tube be inserted into the molten metal precisely at an angle of 45°. Special care is taken for ensuring the same.


Vacuum Pin Tubes are available in varying volumetric capacity as well. For example, you can select tubes that can section half a gram or 1 gram of the sample from the pins. It is quite clear that Evacuated Pin Tubes are a simple apparatus for rapid sampling of molten metal.

Know more about Vacuum Pin Tube

November, 22, 2013

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.


Pioneer Scientific Instrument Corporation (PISCO) is a well-known Manufacturer, Supplier and Exporter of Scientific Laboratory Glass Apparatuses. Apart from Vacuum Pin Tube, the company’s offerings include Membrane Filter Assembly, Sintered Glass Buchner Funnel, Sintered Laboratory Glassware, Sintered Filter Disc, Viscometer Tubes, and Pisco Screw Capped Glassware.
