1. Introduction
This manual provides essential instructions for the safe and efficient use, installation, maintenance, and troubleshooting of the Bradley 120-042 Rotor for Equa-Flo systems. Please read this manual thoroughly before operating the rotor to ensure proper function and longevity of the product.
2. Safety Information
Always adhere to the following safety guidelines to prevent injury and damage to the equipment:
- Ensure the rotor is correctly installed and secured in the centrifuge before operation.
- Do not exceed the maximum rated speed of the rotor or the centrifuge.
- Always balance samples properly to prevent vibration and potential damage.
- Inspect the rotor for any signs of damage or wear before each use. Do not use a damaged rotor.
- Wear appropriate personal protective equipment (PPE) such as safety glasses and gloves.
- Keep hands and loose clothing away from moving parts during operation.
- Refer to the centrifuge's main instruction manual for additional safety precautions.
3. Product Overview
The Bradley 120-042 Rotor is designed for use with Equa-Flo centrifuge systems. It is a critical component for separating substances based on density through rapid rotation. This rotor is engineered for precision and durability in laboratory and industrial settings.

4. Setup Instructions
- Unpacking: Carefully remove the rotor from its packaging. Inspect for any visible damage during shipping.
- Cleaning: Before first use, clean the rotor according to the maintenance instructions provided in Section 6.
- Installation:
- Ensure the centrifuge spindle is clean and free of debris.
- Carefully place the Bradley 120-042 Rotor onto the centrifuge spindle, ensuring it seats properly.
- Secure the rotor using the appropriate locking mechanism of your Equa-Flo centrifuge. Refer to your centrifuge's manual for specific instructions.
- Verify that the rotor is firmly attached and does not wobble.
5. Operating Instructions
Follow these steps for safe and effective operation of the Bradley 120-042 Rotor:
- Load Samples: Place sample tubes into the rotor's designated slots. Ensure all tubes are compatible with the rotor and the centrifuge.
- Balance Samples: Crucially, ensure that samples are balanced symmetrically across the rotor. Imbalance can lead to severe vibration, damage to the centrifuge, and potential injury. Use a balance scale if necessary.
- Close Centrifuge Lid: Securely close the centrifuge lid according to the centrifuge's operating instructions.
- Set Parameters: Set the desired speed (RPM/RCF) and run time on the centrifuge control panel. Do not exceed the maximum speed specified for the rotor.
- Start Centrifugation: Initiate the centrifugation process. Monitor the centrifuge for unusual noises or vibrations during the initial phase of the run.
- Unload Samples: Once the run is complete and the rotor has come to a complete stop, open the centrifuge lid and carefully remove the sample tubes.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Bradley 120-042 Rotor.
- Cleaning:
- After each use, clean the rotor with a mild, non-corrosive detergent and distilled water.
- Rinse thoroughly and dry completely with a soft cloth or air dry.
- Do not use abrasive cleaners or solvents that could damage the rotor material.
- Inspection:
- Periodically inspect the rotor for cracks, corrosion, pitting, or any signs of stress.
- Check sample tube slots for deformation or damage.
- If any damage is observed, discontinue use immediately and replace the rotor.
- Storage: Store the clean, dry rotor in a safe, dry environment away from direct sunlight and extreme temperatures.
7. Troubleshooting
This section addresses common issues that may arise during the use of the Bradley 120-042 Rotor.
| Problem | Possible Cause | Solution |
|---|---|---|
| Excessive Vibration/Noise | Unbalanced samples; improperly seated rotor; damaged rotor. | Ensure samples are balanced. Re-seat the rotor. Inspect for damage and replace if necessary. |
| Rotor not reaching set speed | Overloaded rotor; centrifuge motor issue; incorrect program settings. | Reduce sample load if applicable. Consult centrifuge manual. Verify program settings. |
| Rotor difficult to remove | Rotor stuck due to vacuum or debris. | Apply gentle, even pressure. Ensure spindle is clean before installation. |
If troubleshooting steps do not resolve the issue, contact Bradley customer support or a qualified service technician.
