Product Description
Nitrate testing by cadmium reduction depends on steady, controlled flow through the column. This column is built for that method, with a metering stopcock so you can set and hold the flow rate needed for consistent reduction of nitrate to nitrite.
This listing is for Kimble catalog number 419000-8505: KONTES Cadmium Reduction Column. A BEVEL-SEAL connection holds the glass wool plug and PTFE tubing at the column base, making cleaning and assembly easy. A PTFE BEVEL-SEAL stopcock connector is included as the metering valve. Glass is low-extractable 33 expansion borosilicate meeting USP Type I and ASTM E438, Type I, Class A, and the column references Standard Methods 4500-NO3-E. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
