Product Description
Ammonia nitrogen testing in water calls for a distillation setup that matches the reference method. This KONTES apparatus supplies the flask, head, stopper and condenser in one assembly, so water and wastewater labs can run the procedure with matched components.
This listing is for Kimble catalog number 21500-1000: KONTES General Distillation Apparatus, Stopper Size: 27. All glass is low-extractable, 33 expansion borosilicate meeting USP Type I and ASTM E438 Type I, Class A.
