The Lab-Crest Midi-Dist is suitable for determination of ammonia or phenol in drinking water, ground water, surface water, saline water, domestic waste water, and industrial water. The ability to do ten setups in a single heat block gives you total flexibility and greater efficiency. You can distill one sample or ten as needed, and you can do ammonias or phenols separately or both at once. The system has an extremely small footprint and is completely portable. Both versions (Ammonia and Phenol) are 220V systems.
