XAD-7 (glycol, cresol, phenol 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.

XAD-7 TUBE are ideal for the sampling of glycol, cresol, phenol.

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, thanks to the extractor supplied, it is possible to easily rotate by 90° the porous septum thus removing the tenax without having to break the vial. In this way you avoid possible accidental injury of the user and the shedding of glass for the laboratory

- Range available:

* Standard:
quantity of XAD-7: 75 - 150 mg
internal diameter of the tube: 5,6 mm
external diameter of the tube: 8,2 mm

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

* Jumbo:
quantity of XAD-7: 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 5 pieces. Inside the packaging the tubes are placed in under a vacuum bag.
- 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).
