Thermostatically controlled oven with capacity up to 2500 C.

Beaker for collecting extracted material.


The test procedure for Bitumen Extraction Test includes the following steps:

  • Take precisely 500 grams of the representative sample and deposit it into the extraction apparatus bowl (W1).
  • Completely submerge the sample in benzene.
  • Dry and weigh the filter paper, then position it over the sample-containing extraction apparatus bowl (B). Securely clamp the bowl cover.
  • Position a beaker under the drainpipe to collect the extract.
  • Allow sufficient time, not exceeding one hour, for the solvent to disintegrate the sample before initiating the centrifuge.
  • Gradually increase the centrifuge speed to a maximum of 3600 rpm and maintain this speed until the solvent ceases to flow from the drainpipe.
  • Run the centrifuge until both bitumen and benzene are fully drained.
  • Stop the machine, remove the cover, add 200 ml of benzene to the material in the extraction bowl, and repeat the extraction process.
  • Conduct this process not less than three times until the extraction is clear and not darker than a light straw color.
  • Retrieve the material from the extraction machine bowl, including the filter paper, and dry it to a constant weight in an oven at 1050 C to 1100 C.
  • Finally, cool to room temperature, and weigh the material (W2) and the filter paper (D) separately with an accuracy of 0.01 grams.
