EmStat3 i 3+
EmStat is a small and low cost potentiostat with research grade capabilities. It has eight current ranges from 1 nA to 100 mA (EmStat3+) full scale, with a minimum resolution of 1 pA. It provides the most relevant electroanalytical measurement techniques and is used with the PSTrace software or with PStouch for Android. > Wyślij zapytanie
