High Quality Vacuum Pintubes

 This item is available in longer lengths by request. Different pricing may be required.

NOTE: It is impractical to guarantee tolerance specifications for 100% of pintubes because of occasional variation in primary       glass production of as much as 0.002″ to 0.003″ ID within length of a single pintube.

It is therefore recommended that the cutting from our pintube be weighted when the utmost chemical analytical precision is required.

Simple, Safe, Cost Effective

  • BUR139

    Designed to sample precious metals, this sampler is our smallest diameter pintube. In only a few seconds, your molten metal will fill the chamber, and when quickly immersed in a cooling solution, the precise diameter will make testing the sample as accurate as possible.
    No more pouring and waiting. No more drilling, or messes associated with old methods of creating a sample. Dip, cool, break. A solid pin every time.
    Specs:0.139″ ID (+/- 0.001) x 6″ Length 1,000 pieces/ box
  • BUR159

    BUR159 is primarily used for sampling base metals, although occasionally used for precious metals. This sampler provides a quick homogenous solid pin instantly. Within a few seconds the lab will have its sample. Clear the slag away and immerse you pintube. A slight ‘jolt’ will tell you it’s time to remove the pintube from the molten metal. Quickly cool the sampler, and tap the glass to remove it. Your sample is now ready for testing.
    No more pouring and waiting. No more drilling, or messes associated with old methods of creating a sample. Dip, cool, and break. A solid pin every time.

  • BUR236

    Bur236 is our largest diameter pintube. It has been used for various metals such as alloys, steel, recycled metal, and high carbon metals.
    No more pouring and waiting. No more drilling, or messes associated with old methods of creating a sample. Dip, cool, and break. A solid pin every time.
    Specs:0.236″ ID (+/- 0.001) x 6″ Length ,500 pieces/ box
  • 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.

CERTIFICATION OF QUALITY

Burtec Instrument Inc certifies that Burtec vacuum pintubes are made of borosilicate low expansion glass under close quality control to meet the following specifications.

1) At least 95% have a vacuum better than 1 torr sufficient to draw up most metals hotter than 1800°F and instantly providing a quick-chill homogenous sample. Steel, precious metals, copper and other metals are routinely sampled using the Burtec pintube wherever viscosity is sufficient and temperature is greater than the melting point of borosilicate glass(1775°F).

2) At least 99.5% of pintubes have a precision inner diameter ±0.01”.

3) Standard length is 6” ±¼” to end including the seal off drawn tip. Standard pin diameters (i.d. of tube) are 0.139”, 0.159”, and 0.236”.

Note that it is impractical to guarantee tolerance specifications for 100% of pintubes because of occasional variation in primary glass production of as much as 0.002” to 0.003” i.d. within the length

of a single pintube. It is therefore recommended that the cutting from our pintube be weighed when the utmost chemical analytical precision is required.

Full or partially full boxes of pintubes apparently not meeting the above specifications will be replaced at no cost to the user upon return after Burtec authorization. Burtec will not be responsible for production delays or other problems which may appear related to failure in meeting specifications.

Burtec Instrument provides 3 different sizes of samplers. The various sizes provide different dimensions for all metals. Below are the specifications for each size and what metals they are commonly used with. If you have any questions regarding this information please send us an email through the contact page.
