Note
Fixatives containing mercuric salts, acetic or picric acid will corrode metallic components in the
instrument and shorten instrument life.
If you choose to work with such fixatives, change the processing water at least every 600 cassettes
or 3 cycles, to minimize the damage.
In addition, we recommend regular preventive maintenance by Leica Biosystems Technical Service.
Caution
Reagents other than these listed here may damage components of the instrument. Do not use
acetone, benzene chloroform and trichlorethane in the instrument.
