Agitator Shaft R 50; Maintenance And Cleaning - IKA ULTRA-TURRAX T 50 basic Instrucciones De Manejo

Agitator shaft R 50

Overview (Fig. 2)
The R 50 agitator shaft is a high-speed ball-bearing rotary shaft. A splash
guard seals it against the medium. The maximum immersion depth of the
unit is 180 mm.
The free-wheeling conical shaft is dangerous. Observe the safety
instructions !
The dissolver disc and cage can be removed for cleaning purposes.

Maintenance and cleaning

Drive unit:
The drive unit is maintenance-free but not immune from wear. The carbon
brushes of the motor wear down over time and produce grooves in the
collector. To clean the drive use only water with a detergent that contains
20
tensides, or use isopropylalcohol for stubborn soiling.
Dispersion tools:
The seals in the dispersion tools must be constantly monitored. In the event
of leakage, the suction effect of the rotating shaft can cause the medium to
penetrate as far as the drive unit. If liquid emerges from the side holes at the
top of the shaft tube, stop work immediately and check the seals.
The function of the dispersion heads depends on the condition of the sharp
edges on the rotor and stator. These edges may be blunted very quickly in
abrasive media, reducing the effectiveness of dispersion.
The dispersion tools are cleaned by running them in a solvent which will
dissolve substance residues without harming the seals. Because of the high
flow speed, this is usually sufficient to clean the rotor and stator. The
Designation
dispersion tool must be removed and cleaned immediately after use to
Grooved pin
prevent residues from adhering to the threads of the rotor and stator and to
Deep-groove ball bearing
prevent the formation of undesirable bacteria cultures.

When ordering spare parts, please state the fabrication number on
the designation plate, the type of unit and the designation of the
spare part.
A) Chemical methods
Germicidal solutions (formalin, phenol, alcohol, etc.) are good
general-purpose disinfectants. It is important that all disinfectant
residues are then removed with sterilized water.
B) Sterilization with moist heat. This denotes the use of a steam jet
pressurized to 2 bar at 120 °C.
C) Sterilization with hot air. Hot-air sterilization is usually performed
at 160 °C or 190 °C.
