PrepASH 229 from Precisa is an automatic ashing and drying system (macro TGA) for 29 or 12 samples.The Swiss made PrepASH 229 consists of a muffle furnace combined with an analytical balance and advanced software using a touch-screen user interface. Weighing curves are recorded over time for each individual test sample. This permits automatic end-point determination and control during the entirety of the drying and ashing process. No additional computer is needed. The prepASH provides higher precision and reproducibility of the results through considerable improvements on manual procedures. This is an instrument where no technology transfer data loss occurs and where the entire process is monitored and recorded from start to finish. In one working cycle, up to 29 specimens and a reference pan are ashed fully automatically in accordance with the latest quality guidelines, monitored and recorded within a wide temperature range of 50° to 1000°C. Safety and reliability in the storage of fundamental data and operating parameters are guaranteed.
