5.3 Sterilization

After removal of reflux tube (18) and suction tube/telescopic tube (17) the dispen-
ser can be steam-sterilized (121 °C, 2 bar, 15 minutes) according to DIN EN 285.
The one-piece suction tube is recommended for repeated sterilizations. Place the
device on a cloth and avoid any contacts with hot metal surfaces.
The discharge tube (7) has to be attached to the protective sleeve (6).
In order to prevent loss of adjustment due to heat expansion of the different mate-
rials, the quick lock knob (3) has to be set to minimum 2/10 of its maximum volu-
me. Before you use the dispenser, let it reach room temperature (about 2 hours
cooling time). After autoclaving, check all screw fittings for tightness.
After autoclaving please check all parts for deformations or other changes. Do
not use any deformed or leaking parts. In case of deformation, please return the
device including the autoclave protocols. After autoclaving the dispenser must be
checked and recalibrated if necessary.
