Gas Detector Tubes

Gas Detector Tubes


There are benefits to using gas detector tubes over electronic gas detecting instrumentation for identifying hazardous gases on the spot. 

Detector tubes are a low-cost method of gas detection compared to other forms of gas measurement particularly for gases that are normally only recognised by using sophisticated technology such as PID. Detector tubes don’t require servicing and can be used in hazardous areas.

Gastec Standard Tubes

Gastec gas detector tubes utilise colorimetric technology to perform spot sampling on a library of around 300 hazardous and toxic gases, and chemical vapours in industrial environments. 

a1-cbiss are the master distributor for Gastec tubes in the United Kingdom which means we can offer the lowest priced Gastec tubes. 

You can also quickly search detector tube availability using our online stock check tool.

There are 10 tubes in a pack except for GAS31B (Oxygen). The standard tubes require an air sample to be drawn using the Gastec Sampling Pump (bought separately).

Gastec Tube Sampling Pumps

The Gastec piston style sampling pumps (GV-100S and the GV-110S) are easy to use, only require minimum effort and are used for sampling with all Standard Gastec Tubes, Polytec Tubes and for the use with the Gastec Pyrolyzer System.

An alternative to using the handheld sampling pump, is to use the automatic pump.

Gastec Kits

The Gastec Starter Kit assists with COSHH assessment, confined space analysis, fume hood assessments.

If you are new to Gastec, buying a Starter Kit will provide you with everything you need to get up and running and save you money.

Gastec Air Current Smoke Tubes

Gastec airflow smoke tubes generate white smoke to allow the user to; visualise airflow behaviour within air ducts and detect leaks within fume hoods.

Gastec Polytec Tubes

Polytec tubes are used in situations where unknown hazardous substances are present. 

The Polytec tubes are commonly used by occupational hygienists or firefighting HazMat teams going into a situation where they need to quickly establish which gases they are faced with.

The Gastec Polytec system requires the Model GV-100S Gas sampling pump (bought separately) to draw air through the tube.

Gastec Automatic Pump Tubes

An alternative to using the Gastec handheld sampling pump, is to use the Gastec automatic pump. Tubes are available for Acetone, Benzene, Chlorine, Formaldehyde, Hexane, Hydrogen Cyanide, Methanol, Styrene, Toluene, Xylene.

With a huge range of Gastec products available, we can also offer a range of Gastec accessories to make using your Gastec detection products easier – Sample extension hoses up to 30 metres, extendable sampling poles up to 2.8 metres, hot probe sampling probes to measure gases up to 600ºC and the one-handed adapter are just some of the products that enable you to remove obstructions and get the job done.
