4. Setup

1. Unpacking: Carefully remove the centrifuge from its packaging. Retain all packaging materials for future transport or storage.
2. Placement: Position the centrifuge on a stable, level, and vibration-free surface. Ensure adequate clearance around the unit for proper ventilation.
3. Power Connection: Connect the provided power cord to the centrifuge's power input and then to a grounded electrical outlet.
4. Initial Inspection: Before first use, inspect the rotor and rotor chamber for any debris or damage. Clean if necessary according to the maintenance section.

5. Operation

5.1 Loading Samples

1. Press the OPEN button to unlock and open the centrifuge lid.
2. Carefully place sample tubes into the rotor. Ensure tubes are balanced symmetrically to prevent imbalance during operation. Refer to Figure 3 for rotor chamber view.
3. Close the lid firmly until it latches securely.

5.2 Selecting Programs

The CM-50MP offers pre-set programs and a custom program option, displayed on the digital screen.

• Pre-set Programs: Use the MODE button to cycle through available pre-set programs optimized for common nucleic acid extraction steps. The display will show program parameters such as Timer, RPM, RCF, and Brake settings.
• Custom Program: To create a custom program, press SET to enter parameter adjustment mode. Use the + and - buttons to adjust parameters like Timer, RPM, RCF, and Brake settings. Press SET again to confirm each parameter.

5.3 Starting and Stopping

1. After selecting or setting the desired program, press the START/STOP button to begin operation.
2. To stop operation prematurely, press the START/STOP button again.
3. The MIX/STOP button can be used to initiate mixing functions or to stop a mixing cycle.

5.4 Mix, Spin, and Shake Functions

The centrifuge integrates specific functions for various laboratory procedures:

• Mix: Activates the semi-automated vortex and mixing functions for reagents, ensuring thorough sample preparation.
• Spin: Initiates the centrifugation process at the set RPM/RCF, separating components based on density.
• Shake: Provides a shaking action for specific applications requiring agitation.

Refer to the display and control panel for specific button functions and indicators during operation.

6. Maintenance

6.1 Cleaning

Regular cleaning ensures optimal performance and longevity of the centrifuge.

• Exterior: Wipe the exterior surfaces with a soft, damp cloth and a mild, non-abrasive detergent. Avoid harsh chemicals or solvents.
• Rotor Chamber: Clean the rotor chamber with a soft cloth. If spills occur, clean immediately with a suitable laboratory disinfectant.
• Rotor: Remove the rotor for cleaning. Wash with mild detergent and rinse thoroughly with distilled water. Ensure it is completely dry before re-installing.

6.2 Inspection

Periodically inspect the rotor, rotor chamber, and lid for any signs of wear, corrosion, or damage. Pay close attention to the rotor's integrity. If any damage is observed, discontinue use and contact ELMI support for assistance.
