Abstract

A safety apparatus (12; 12') for millibaric pressure control in an inert atmosphere for liquid solutions (14; 14') with high reactivity contained inside a tank (16; 16') comprises: a differential U-shaped pressure gauge (18; 18') suitable for use with a non-reactive liquid, having a first end (20; 20') and a second end (22; 22'). The first end (20; 20') is in fluid connection with an environment having a known pressure; and the second end (22; 22') is in fluid connection with said tank (16; 16'), and with an output line (24; 24') for said inert gas contained inside said tank (16; 16').
