Product Description
Water and wastewater color tests depend on tubes whose scales line up from one tube to the next. Matched sets of these tall Nessler tubes keep the graduated rings within a tight height tolerance so comparisons stay fair. They suit environmental and municipal water testing labs.
This listing is for Kimble catalog number 45315A-50100: KIMAX Color Comparison Tube, 375 mm, 275-295 Scale Length, Matched Set of 6, 50 & 100 mL. The tubes are borosilicate glass 3.3 with shadowless bottoms and white ceramic enamel rings tied to specific liquid volumes. In matched sets, ring height varies by no more than 1.5 mm on 50 mL and 2.0 mm on 100 mL tubes. The 50 mL size is cited in APHA Standard Methods. Unmatched cases and matched sets of 6 or 12 are offered. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
