Excel 2.5L Ultrasonic Cleaner

Ultrasonic cleaning uses high-frequency sound waves transmitted through a suitable cleaning solution. These sound waves create millions of microscopic bubbles in a process known as cavitation.

As the bubbles form and collapse, they generate gentle cleaning action around the surfaces of immersed instruments. This helps loosen and remove debris from exposed surfaces, joints, hinges and other areas that may be difficult to clean manually.

Ultrasonic cleaning is a cleaning process, not a sterilisation process. Where instruments require sterilisation, they should be appropriately rinsed, dried, inspected and sterilised after ultrasonic cleaning in accordance with the instrument manufacturer’s instructions and local infection-control procedures.

Reusable instruments should be thoroughly cleaned before sterilisation. Residual contamination can interfere with the subsequent sterilisation process by preventing steam or other sterilising agents from reaching all instrument surfaces effectively.

Ultrasonic cleaning helps provide a consistent method of instrument cleaning while reducing the amount of direct manual brushing required. This can be particularly useful around joints, serrations and other complex instrument surfaces.

1. Place the ultrasonic cleaner on a stable, level and dry work surface.
2. Check that the stainless steel tank is clean before use.
3. Prepare a suitable ultrasonic cleaning solution according to the detergent manufacturer’s instructions.
4. Fill the tank to the appropriate operating level. Do not exceed the maximum fill level.
5. Where fresh cleaning solution has been added, degas the solution before processing instruments where recommended.
6. Place suitable instruments into the supplied basket. Instruments should not be placed directly on the base of the tank.
7. Lower the basket into the cleaning solution and fit the lid.
8. Select the appropriate cleaning cycle and temperature in accordance with the instrument and cleaning-agent instructions.
9. After the cycle is complete, carefully remove the basket.
10. Rinse, dry and inspect instruments as required before proceeding to any subsequent sterilisation process.

Freshly prepared cleaning solution naturally contains dissolved air. This trapped air can reduce the effectiveness of ultrasonic cavitation during the first cleaning cycle.

Running the ultrasonic cleaner briefly with fresh solution before adding instruments helps remove dissolved gases and allows cavitation to occur more consistently.

Follow the equipment and detergent manufacturer’s instructions regarding the appropriate degassing procedure.

1. Switch off and disconnect the unit from the mains before cleaning or emptying the tank.
2. Allow the cleaning solution to cool before handling where heated cycles have been used.
3. Dispose of used cleaning solution in accordance with the detergent manufacturer’s instructions and local procedures.
4. Rinse and wipe the stainless steel tank using a soft cloth.
5. Clean the basket and removable accessories regularly.
6. Avoid abrasive pads, corrosive products or aggressive cleaners that could damage the tank or housing.
7. Do not immerse the electrical unit, mains lead or controls in water.
8. Allow all surfaces to dry before the next use.

• Ultrasonic cleaning does not sterilise instruments.
• Only clean instruments and materials that are compatible with ultrasonic cleaning.
• Always follow the instrument manufacturer’s reprocessing instructions.
• Use only a suitable ultrasonic cleaning solution at the recommended concentration.
• Do not operate the cleaner without sufficient liquid in the tank.
• Do not place instruments directly on the bottom of the stainless steel tank; use the supplied basket.
• Do not overfill the tank or overload the basket.
• Take care when handling heated cleaning solution and instruments.
• Keep the electrical controls, plug and power lead dry.
• Do not use the unit if the power lead, plug, housing or tank is damaged.
• Disconnect the unit before draining, cleaning or carrying out routine maintenance.
• After cleaning, follow the appropriate rinsing, drying, inspection and sterilisation process required for the instrument.
