The HI731335N are the replacement caps that screw on the glass cuvettes used with portable and benchtop turbidity meters. See below for a complete list of compatible part numbers. The HI731335N includes 4 caps that are used with the HI731331 glass sample cuvettes.
HI731318 are microfiber cloths for wiping the cuvettes used in Checker HC (HI700 series) handheld colorimeters, photometers (HI96000 portable series and HI83000 benchtop series) and turbidity meters. These cloths remove dirt, grease and fingerprints from the vials so that the glass is clean for the unimpeded transmission of light.
