Micro Digestors provide accurate results for Kjeldahl digestions using either 30 or 100 milliliter flasks. Each heater has individual infinite heat control to provide precise heat to each sample. Micro Digestors are fully assembled and ready to use. Simply plug into a suitable electrical receptacle and connect to a water aspirator or use in a fume hood. The RapidStill I is the ideal companion for the Micro Digestor.
