General precautionary rules
•
Handling of solvents
Check all pump tubings and all input and output leads periodically for
possible leaks. Follow the relevant instructions regarding the handling
of flammable and/or toxic solvents and their disposal.
•
Regular exchange of pump tubings
Pump tubings constitute consumable material and must be replaced
from time to time (see section 4.4). Suitable measures must be taken
so that any leak which might occur in the pump tubing or connections
during unattended operation will cause no damage (placing the
instrument at the bottom, collection device for any liquid which may
