Autoclaving - BRAND Dispensette III Mode D'emploi

This instrument is autoclavable at 121 °C (250 °F), 2 bar absolute (30 psi) with a holding time of at least
15 minutes according to DIN EN 285. Before autoclaving, the instrument must be cleaned carefully (page
48-50). Lift the piston out of the cylinder (page 49). For autoclaving with mounted filling tube, the filling
valve with olive-shaped nozzle is recommended (page 55).
1.
Prior to the first autoclaving
Remove built-in inelastic PTFE-sealing ring (R) and replace with the
supplied elastic sealing ring made of FKM (S).
Note:
FKM has limited chemical resistance!
2.

Autoclaving

a) Loosen screw connections (Fig. a).
b) Pull out the recirculation tube and the telescoping filling tube.
c) Check that the filling valve is securely seated (Fig. c). If the
rigid PFTE ring has been installed, the filling valve must also
be loosened.
In the digital model, check that the piston mount is securely
seated (Fig. c').
d) Autoclave the instrument with the piston pushed all the way
downward, and with the filling tube and recirculation tube
disconnected. Avoid contact with metallic surfaces. The
mounting tool can also be autoclaved.
Note:
Do not reassemble the instrument until it has cooled down to
room temperature (Cooling time approx. 2 hours).
After every autoclaving, inspect all parts for deformities or dam-
age. If necessary, replace them.
It is the user's responsibility to ensure effective autoclaving.
