NEWTRY 800D Electric Centrifuge Machine Instruction Manual

1. Product Overview

The NEWTRY 800D Electric Centrifuge Machine is a compact and efficient benchtop centrifuge designed for laboratory and scientific applications. It features adjustable time and speed controls, an efficient motor, and a durable high-strength plastic shell, making it suitable for various separation tasks.

Key Features:

• Efficient Motor: Motor components are designed for high tightness, stable operation, and zero error, ensuring efficient and reliable performance.
• Pure Copper Coil: Utilizes a 100% pure copper coil for stronger magnetic force, robust rotor power, higher rotation speed, and greater centrifugal force.
• Smooth Operation: The motor and base plate are connected by a damping column, and an integrated circuit ensures smooth rotor operation, minimizing vibration and enhancing stability.
• Durable Construction: Features a high-strength plastic shell with a simple and user-friendly structure.
• Low Noise: Equipped with a round centrifugal head and top cover to significantly reduce operational noise.

2. Safety Information

Please read all safety warnings and instructions carefully before operating the centrifuge. Improper use can lead to equipment damage or personal injury.

• Always place the centrifuge on a stable, level surface to prevent movement during operation.
• Ensure the power supply matches the machine's requirements (110V US Plug, 60HZ).
• Do not open the lid while the rotor is spinning. Wait until the rotor has completely stopped.
• Always load tubes symmetrically to maintain balance and prevent excessive vibration. Uneven loading can damage the machine and pose a safety risk.
• Do not overfill or underfill centrifuge tubes. It is recommended that the capacity of centrifuge tubes should be no less than 30% and no more than 80% filled.
• Use only appropriate centrifuge tubes that fit securely in the rotor.
• Keep hands and loose clothing away from the rotating parts.
• In case of unusual noise or vibration, immediately turn off the machine and unplug it.
• Do not operate the machine if any parts are damaged or missing.

3. Components and Parts

The NEWTRY 800D Centrifuge consists of the following main components:

• Main Unit: Houses the motor, control panel, and rotor chamber.
• Rotor: The rotating component that holds the centrifuge tubes. The 800D model has a capacity for 6 tubes of 20ml each.
• Control Panel: Features a time adjustment knob and a speed adjustment knob.
• Lid: Covers the rotor chamber during operation.
• Power Cord: For connecting the unit to an electrical outlet.
• Suction Cup Feet: Located at the base for stability and vibration dampening.

4. Setup Instructions

1. Unpacking: Carefully remove the centrifuge from its packaging. Inspect for any signs of damage during transit.
2. Placement: Place the centrifuge on a firm, level, and stable workbench or surface. Ensure there is adequate space around the unit for ventilation and safe operation. The suction cup feet should firmly grip the surface.
3. Power Connection: Connect the power cord to the centrifuge and then plug it into a grounded 110V US electrical outlet.
4. Initial Check: Before first use, ensure the time and speed knobs are set to '0' (off position).

5. Operating Instructions

Follow these steps to operate your NEWTRY 800D Centrifuge:

1. Prepare Samples: Fill your centrifuge tubes with the samples to be processed. Remember to adhere to the recommended filling levels (30-80% full).
2. Load Tubes: Open the centrifuge lid. Carefully insert the filled tubes into the rotor slots. It is crucial to load tubes symmetrically to ensure balance during centrifugation. If using an odd number of tubes, balance the rotor by placing a tube of equal weight (e.g., filled with water) opposite your sample tube.
3. Close Lid: Securely close the centrifuge lid. Ensure it is properly latched before starting operation.
4. Set Time: Turn the 'TIME' knob to set the desired centrifugation duration (0-60 minutes). The machine will start automatically once a time is set.
5. Set Speed: Turn the 'SPEED' knob to set the desired rotation speed (0-4000 RPM). Adjust the speed gradually if necessary.
6. Start Centrifugation: The machine will begin spinning once the time knob is turned from the 'OFF' position.
7. Monitor Operation: Observe the centrifuge during the initial moments of operation to ensure stable running and minimal vibration.
8. Completion: The centrifuge will automatically stop once the set time has elapsed. Wait for the rotor to come to a complete stop before opening the lid.
9. Unload Samples: Open the lid and carefully remove your processed samples.

6. Maintenance

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

• Cleaning: After each use, especially if there are spills, clean the rotor chamber and the exterior of the machine with a soft, damp cloth and a mild detergent. Do not use abrasive cleaners or solvents.
• Drying: Ensure all parts are thoroughly dry before closing the lid or storing the machine.
• Rotor Care: Periodically inspect the rotor for any signs of wear or damage. Ensure the tube sleeves are clean and free of debris.
• Storage: Store the centrifuge in a clean, dry, and dust-free environment when not in use.
• Power Cord: Check the power cord regularly for any damage. Do not use if the cord is frayed or damaged.
