A concentrated Glauber salt solution is diluted in 5 steps in a Wellplate 6 (1 zu 10, 100, 1000, 10.000, 100.000 ).
Direct current is measured between two pins fixed inside a stopper. The voltage is 9 V.
Eine konzentrierte Glaubersalzlösung wird in einer Reaktionsplatte mit 6 Kammern (WP6) in 5 Stufen (1 zu 10, 100, 1000, 10.000, 100.000 verdünnt.
Zwischen zwei in einem Stopfen fixierten Stecknadeln wird der Stromfluss bei 9 Volt Wechselspannung (beginnend bei der stärksten Verdünnung) gemessen.
