Chemical detector tubes provide an affordable method for quickly measuring specific gases on-site, including a variety of flammable and toxic gases and vapors. They are one of the most dependable and tested ways to detect harmful gases, pollutants, and toxic substances. The detection process doesn’t depend on a lab, calibration, or electricity. All chemical detector tubes work in a similar way, but the size of the tube and the design of the pump used to pull air through the tube can differ between manufacturers.

Gas Detector Tubes
Chemical Detector Tubes
The detector tubes are used with the ASP-40 piston hand pump. An air sample is pulled through a narrow tube that has a particular chemical for detecting gases, which makes a color change. The length of the color spot shows how much of the gas is present, and this is read directly from the scale printed on the tube. The setup with the piston pump and tube usually measures the gas amount based on one push of the pump.
Air Sampling Pump and Accessories
The ASP-40 pump is a light and durable piston and barrel type of air sampling pump that makes a vacuum inside the pump barrel, which pulls in an exact amount of sample air through the connected gas detector tube. It has an indicator that changes color to show when the sampling is done. The Uniphos ASP-40 pump is simple to use and works well with all the gas detector tubes in the Uniphos range.
Speciality Tubes
Smoke tubes are a good way to check for slow-moving air in places like mines, ducts, and hoods. These tubes are made of sealed glass and contain a chemical that gives off a strong-smelling gas. To use them, you break both ends of the tube and insert one end into a rubber bellows. Then, you use the bellows to push air through the tube, which makes white smoke come out the other end. This white smoke helps you see even the smallest air movements.

KwikDraw Tubes
KwikDraw detector tubes, which used to be called MSA/AUER detector tubes, are a dependable way to check for over 200 different harmful gases and vapors. To use them, you connect the tube to a special pump that looks like a bellows. With each push, the pump pulls in a set amount of air. Inside the tube, there's a chemical that reacts when it comes into contact with the gas you're testing for. This reaction causes the chemical to change color. The longer the color changes along the tube, the higher the amount of the harmful gas or vapor in the air. You can measure this color change using the scale printed on most of the tubes.
KwikDraw Pumps
The KwikDraw Deluxe Pump comes with an integrated end-of-stroke indicator and is a bellows-style pump designed to pull gases and vapors through KwikDraw Gas Detector Tubes by simply squeezing its handle. To get a precise 100 ml sample, the user holds the hand grip and pushes the knob. The pump's compression system guides the movement to operate a spring-loaded bellows pump. There's an easy-to-read stroke counter built into the pump that shows exactly how many times the pump has been pressed and stops the action when the stroke is fully compressed.
KwikDraw Speciality Tubes
Most of us don't think much about clean air to breathe, but for people working in different industries, it can mean the difference between staying safe and facing serious danger. Uniphos knows this and is dedicated to helping industries that need reliable equipment like our Breathing Air Quality Monitoring Kits. These kits are used to check the purity of air coming directly from air compressors, breathing air cylinders, or medium-pressure air lines that supply air for airline systems and pneumatic machines. The Airtester quickly and accurately shows the levels of water vapor, oil, carbon dioxide, carbon monoxide, and nitrous fumes in the air.
