Colourimetric Sensor Chamber

This chamber allows you to test colorimetric sensors without the need for a bubbler. The sensor made of silica gel spotted with metalloporphyrins is placed in the bottom. Specific analytes can be placed in the tiny disposable boxes to keep the chamber clean, which allows you to reuse the chamber for several different analytes without contamination. The chamber is sealed using a microscope slide and vacuum grease or vaseline to isolate the analyte vapors from the outside air.
