6 Test of a PXE based scintillator for Borexino
6.3 The PXE Tests in the CTF
6.3.1 The liquid handling system Module-0 and the column plant
For the scintillator and fluor preparation and first filling of the CTF1 in 1995 a temporary liquid
handling system had been installed by the Munich group. In context with the development of
a solid column purification plant the temporary system was replaced by Module-0, the first
modular part of the BOREXINO liquid handling system. It was originally constructed in 1996,
and upgraded during 1998 and 1999. Module-0 serves as a flexible liquid handling unit for
various filling and purification operations for BOREXINO and the CTF:

- volumetric loading and unloading of liquid scintillator to/from the CTF Inner Vessel;
- fluor mixing;
- purification of liquid scintillator with a silica gel column;
