GAS121L Benzene Gastec Detector Tubes 0.1 – 65ppm
GAS121L Benzene Standard Gastec Detector Tubes
Gas detector tubes are glass tubes that are filled with a chemical reagent that absorbs and reacts with the target gas or vapour being measured. Gastec tubes do not contain hazardous substances
A colorimetric stain (a colour change) is created. For most tubes, the concentration is read directly from the pinpoint accurate measurement scale on each tube.
The Gastec detector tube system is comprised of a handheld Gastec air sampling pump and Gastec detector tubes
Shelf Life – a1-cbiss will never dispatch detector tubes with less than 3 months remaining before expiry. a1-cbiss employ a stock rotation policy of first in, first out.

Q. On the package of Benzene tubes GAS121L, it says “stored at a cool place”, which in the catalogue says 0-10C. What is the effect on the tube if it is stored at room temperature? If the packet does not say “stored at refrigerated place” and we store them at room temperature. Is this unacceptable?
A. Gastec defines cool place as 0 – 25 °C. Store below 10 °C / 50 °F (refrigerated storage)” means about 0 – 10 °C
You can store the GAS121L tubes in a room if it is between 0 – 25°C. However, chemical reagents inside the tube will react more effectively when the tubes stored cooler place like a refrigerator. Please also be advised not to store the tubes under 0 °C because some chemical reagents inside tubes are wet.
