ULR CHEMets®
Ultra Low Range
Self-Filling Ampoules
for Colorimetric Analysis
ULR (Ultra Low Range) CHEMets® ampoules are designed for maximum simplicity and accuracy in testing low analyte concentrations.
Each ULR ampoule is 8 mm in diameter and 250 mm in length with a tapered, prescored tip. Reagents are vacuum sealed inside.
The ULR CHEMets® Method.
The ULR CHEMet™ ampoule is immersed in the sample and the tip is snapped off. The correct volume of sample is drawn in, and a small inert gas bubble forms. Sample and reagent are mixed by tilting the ampoule so that the bubble travels from end to end. In 2 minutes or less, the resulting color is compared to the appropriate color standards to quantify the result.
ULR CHEMets® enable the user to measure concentrations at very low levels. A cylindrical comparator is used to read the test results. The filled test ampoule is placed in the center of the cylinder and compared with eight color standards surrounding it.
Test kits contain 30 ampoules, comparator(s), accessory solutions (when necessary), snap cup, MSDS, and instructions. Refill packs of 30 ampoules, and accessory solutions, are available.
Comparators have a 2-year shelf-life. Material Safety Data Sheets are provided in test kits.
