| Popis: | An inexpensive steam generator and distillation head for nicrokjeldahl determinations is described. The generator consists of a soil moisture pressure plate extractor with heating coils and a water level control chamber. A distillation head and vacuum system is also described which allows for vacuum removal of waste from the tubes after distillation and rinsing of the distillation head between runs. |
