Gastec Pyrotec Tubes

The Gastec Pyrotec Tubes require the additional use of the portable Pryotec Pyrolyzer (model 810-840 unless specified otherwise) accessory to quickly, accurately and quantitatively measure fluorochlorocarbons, nitroparaffins, anesthetic gases, and other hard-to-detect compounds on-the-spot, as listed in the table below. The sample enters the Pyrotec tube where it is thermally decomposed into substances that react chemically with the reagent to give the resultant colour change.

The Pyrolyzer is not suitable for use in hazardous atmospheres.

Gastec Colour Detector Tubes

Tubes are supplied in packs of 10 unless noted otherwise (shown by + or ~).
