CARBON TUBES (Volatile Organic Compounds sampling)


The  NIOSH, OSHA ed EPA regulations require the use of absorbent tubes for the �active� sampling of many toxic chemicals that are present in the atmosphere or into conveyed streams as gases and vapors. From the amount of sampled substances, and analytically determined, knowing the total volume of sampled air, it is possible to find  the concentration present in the environment.

CARBON TUBE, tubes with activated charcoal, are ideal for the sampling of most volatile organic compound.

The tubes, manufactured by AQUARIA, have been developed in compliance with the Ley No.81/2008: the two ends are in fact equipped  with two tight caps. Before use it is no longer necessary to break the tube, but just remove those caps.

Moreover, thank to the supplied extractor, you can easily rotate 90 degrees the porous membranes thus removing the coal without having to break the tube. This will prevent possible accidental injury of the user and the spreading of glass in the laboratory.


- Range available:
  * Standard:
     quantity of charcoal: 75 - 150 mg
     internal diameter of the tube: 5,6 mm
     external diameter of the tube: 8,2 mm

   * Large:
     quantity of charcoal: 200 - 400 mg
     internal diameter of the tube: 6,4 mm
     external diameter of the tube: 8,7 mm

   * Jumbo:
     quantity of charcoal: 200 - 800 mg
     internal diameter of the tube: 7,5 mm
     external diameter of the tube: 10,5 mm

- Porous septum: in polyethylene (to avoid adsorbing phenomena during the sampling), with high porosity to minimize the pressure drop
- Tubes ends closed by caps sealed with two stopper
- Available in packs of 10 and 40 pieces. Inside the packaging the tubes are placed in under vacuum bags of 5 pieces.
- The lot number and expiration date are reported on esch box. The user can also record data from sampling (identification number of the tube, place, date, start time and end of sampling).
- Each package is supplied  with a quality control certificate (and the chromatograph), where it is declared the BTEX quantity (in �g/g) found in 3 random sampling tubes.
