ABSTRACT:
A histological tissue specimen treatment process includes the steps of placing a plurality of histological tissue specimens to be processed in chamber structure, closing the chamber structure, monitoring the level of a first tissue processing material flowed into the chamber structure with a sensor system that responds to a characteristic of the first tissue processing material, terminating the flow of the first tissue processing material when the histological tissue specimens are immersed in the first tissue processing material, flowing the first tissue processing material from the chamber structure after the histological tissue specimens have been immersed in the first tissue processing material for a predetermined time interval, monitoring the level of a second tissue processing material flowed into the chamber structure with the sensor system in a changed sensitivity condition, terminating the flow of the second tissue processing material when the plurality of histological tissue specimens are immersed in the second tissue processing material, and flowing the second tissue processing material from the chamber structure after the plurality of histological tissue specimens have been immersed in the second tissue processing material for a predetermined time interval.
