Risk of injury to eyes, skin and respiratory
During the first days of system use, check the screw joint between the syringe
and valve to avoid leaks and the potential escape of reagents.
When working with chemicals and/or solvents, always observe the relevant acci-
dent prevention regulations and wear appropriate personal protective clothing for
eye, face, hand, body and/or respiratory protection.
Make sure that the tubes are never kinked.
Regularly check the system as well as all tubes and connections for
leaks, condition and cleanliness.
To prevent twisting of the tubes, you should always connect flange tube
connections before those with grommets.
The system is delivered with two tubes; these are supplied pre-installed
on the TitraLab and only need to be connected to the relevant titrant
bottle and to the electrode.
