Glass laboratory tube SMT

Uniphos Smoke tubes are an apt tool to determine low velocity air movements in mines, ducts, hoods, etc. Smoke tubes are sealed glass tubes filled with a pungent gas producing chemical compound. The tubes are used by breaking both ends of the smoke tube and inserting one end of the tube into a rubber bellow. The bellow is used to pump air through the tube, resulting in white smoke coming out of the other end. This white smoke allows the determination of even the smallest air flow. Smoke tubes can also be used to test the performance of fume hoods, exhaust discharges, dryers, stacks, etc. They can also be used to perform respiratory fit tests of respirator mouth pieces as per OSH29CFR1910.134
