We are glad to introduce ourselves as one of the leading Vacuum Tube Manufacturers and offer Vacuum Pin Tube, since 1961 under PISCO™ brand. Designed as per the international standards, our Vacuum Pin Tubes are extensively used for collecting sample from molten steel/gold/silver etc. required for hydrogen analysis. The use of finest grade borosilicate glass endows unmatched resistance against harmful substances. This leading attribute of our Evacuated Pin Tube makes them a highly reliable product. Our Vacuum Glass Pin Tubes are sealed at both ends with a thin walled bulb (weak point) at one side. PISCO™ brand Evacuated Pin Tubes feature a thin (0.5 mm. approx.) wall bulb section (weak point) which breaks on contact with molten metal. The molten metal then enters the tube to form a solid, slag-free metal pin every time. The clients can obtain these Pin Tubes, at market leading prices from us.

Operation :

In operation, the Vacuum Pin Tube is held in a simple spring holder. The molten metal is removed from the furnace and the slag is pushed aside. The pin tube is immediately inserted into the molten metal at an angle of 45 degrees (approx.) until the thin walled bulb section is completely immersed and this breaks the weak point of the glass tube and fills the pin tube with molten metal.

PISCO™ Screw Capped Glasswares are ideal for laboratory culture work. Free interchange between the atmosphere inside and outside the mouth of the glassware, completely satisfying the gas requirements for aerobic culture, is easily attained by slightly loosening the caps. Can withstand repeated autoclaving since the liner used in it is made of pure silicone rubber with PTFE facing.

Available in 3 models with different sizes :

Culture Tubes, R.B./ F.B., Cat. No. T-80 : 5 ml., 10 ml., 15 ml., 30 ml. and 60 ml.
Conical Flask, Cat. No. T-40 and 575b : 10 ml., 25 ml., 50 ml., 100 ml., 150 ml. and 250 ml.
Bottles, Cat. No. T-10 and 442c. : 10 ml., 25 ml., 30 ml., 50 ml., 60 ml., 100 ml., 125 ml. and 250 ml.
