Thermo Scientific Centrifuge CL10 Benchtop User Manual

1. Introduction

This manual provides essential information for the safe and efficient operation of the Thermo Scientific Centrifuge CL10 Benchtop. The CL10 is designed for low-speed clinical applications, offering a broad choice of rotors and user-friendly controls. It is capable of spinning various tube configurations with minimal sample temperature increase and very low noise levels.

2. Safety Information

Always read and understand all safety precautions before operating the centrifuge. Failure to do so may result in injury or damage to the instrument.

• Ensure the centrifuge is placed on a stable, level surface.
• Do not operate the centrifuge with a damaged power cord or plug.
• Always balance rotors correctly before operation to prevent imbalance detection and potential damage.
• Do not open the centrifuge lid while the rotor is spinning.
• Use only rotors and accessories approved by Thermo Scientific for this model.

3. Setup

3.1 Unpacking and Inspection

1. Carefully remove the centrifuge from its packaging.
2. Inspect the unit for any visible damage incurred during shipping. Report any damage to the carrier and supplier immediately.
3. Verify that all components listed in the packing list are present.

3.2 Placement

Place the centrifuge on a sturdy, level laboratory bench capable of supporting its weight (approximately 101 lbs or 45.8 kg). Ensure adequate clearance around the unit for ventilation and access.

3.3 Power Connection

Connect the power cord to a grounded 230V electrical outlet. Ensure the power switch on the centrifuge is in the OFF position before connecting.

4. Operating Instructions

4.1 Rotor Installation and Balancing

1. Open the centrifuge lid.
2. Carefully place the desired rotor onto the motor shaft, ensuring it seats properly.
3. Secure the rotor according to the specific rotor manual (e.g., tightening the rotor nut).
4. Load samples into the rotor buckets. Ensure all tubes are balanced by weight. For example, if using 16 x 5/7mL Vacutainer tubes, ensure opposing tubes have equal weight. If using 6 x 50mL conical tubes, ensure opposing tubes are balanced.
5. Close the centrifuge lid securely.

4.2 Control Panel Overview

The CL10 features a digital microprocessor control panel for easy operation. Key controls include:

• Speed/RPM Display: Shows the current rotational speed.
• Time Display: Shows the remaining run time.
• Start Button: Initiates the centrifugation run.
• Stop Button: Halts the centrifugation run.
• Parameter Adjustment Buttons: Used to set speed, time, and other parameters.

4.3 Starting a Run

1. Turn on the main power switch.
2. Use the parameter adjustment buttons to set the desired speed (RPM) and run time.
3. Press the Start button. The centrifuge will accelerate to the set speed.
4. The digital display will show the current speed and remaining time.

4.4 Stopping a Run

The centrifuge will automatically stop when the set time expires. To stop a run manually:

• Press the Stop button. The rotor will decelerate and come to a complete stop.
• Wait until the rotor has completely stopped before attempting to open the lid. The lid will unlock automatically once the rotor is stationary.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your CL10 centrifuge.

5.1 Cleaning

• Exterior: Clean the exterior surfaces with a damp cloth and mild detergent. Avoid abrasive cleaners.
• Rotor Chamber: Periodically clean the rotor chamber with a damp cloth. Ensure no liquid enters the motor area.
• Rotors and Accessories: Clean rotors and accessories after each use, especially if spills occur. Refer to the specific rotor manual for detailed cleaning instructions.

5.2 Inspection

• Regularly inspect the power cord for any signs of damage.
• Check rotors and buckets for corrosion, cracks, or other damage. Replace damaged components immediately.
