Description
The original Uniphos tubes for formaldehyde and other chemicals are 5 mm in diameter and are used with the precision ASP-40 piston hand pump, delivering 100 cc for a full stroke or 50 cc for a half stroke volume. The typical sample time per stroke is two minutes and is based on the specific tube. The narrow tube and fine granular size of the reagent carrier used in the 5 mm tubes produce distinct stain characteristics and sharply defined endpoints to help interpret the indication on the tube. The piston style pump and tube configuration often have the standard range of measurement based on a single pump stroke. These short term colorimetric detector tubes provide a simple and reliable means of quickly determining the presence and concentration about 300 gases and vapors in ambient air at the workplace, in process gases, checking for contaminants in compressed gases and at hazardous materials scenarios.
Gas Detector Tubes provide a simple measurement of chemicals in gas samples. The tubes are pre-calibrated, take only a few minutes to complete sampling, and the concentration is read directly from the length of color stain. Tubes are available for over 150 different chemicals and concentration ranges.
Buy 10 boxes of Uniphos tubes for formaldehyde tubes and trade out your old Draeger tube pump for a new Uniphos tube pump.
