Gastec Polytec Tubes

The Polytec system consists of a Gastec sampling pump and a Polytec tube - a unique tube that has between 1 to 8 reaction layers to determine multiple unknown substances simultaneously in the sample by a colour change. It is ideal for use by the emergency services. It is a qualitative rather than quantitative measure.

Polytec Tubes
  • Easy determination of constituents in the sample
  • No costly equipment or specialists required

Tubes are supplied in packs of 10.
