The TD4C Tabletop Low Speed Centrifuge, powered by MRP and distributed by MEDREPPRO LLC, is a compact and lightweight laboratory instrument designed for the physical separation of components within a sample based on their different densities. This is achieved by setting specific centrifugal speed and time parameters. For instance, it can separate blood into three layers—PPP, PRP, and Red cells—typically at 3500 rpm for 8 minutes. After centrifugation, users can extract the desired materials from the tubes.

Important Safety Notices:

To ensure safe operation and prevent potential accidents, users must adhere to the following safety protocols:

1. Always unplug the main power cord when performing maintenance or when the centrifuge is not expected to be used for an extended period.
2. Load the rotor with samples arranged symmetrically. Opposing tubes must have equal weight. If necessary, use "water blank" tubes to balance samples of unequal weight. Do not rely on visual assessment of volume for balancing; always use a pan balance provided in the centrifuge room.
3. Never exceed the maximum speed specified for the rotor.
4. Do not use a rotor that shows signs of damage, such as missing O-rings, scratches, corrosion, or cracks.

Main Specification and Technical Parameters:

• Max speed: 4000 rpm
• Max RCF: 1880 xg
• Max volume: 8 x 20 ml
• Noise: ≤55 dBA
• Timer: 0 – 99 min
• Net weight: 6.5 KG
• Dimension: 310 x 270 x 220 mm
• Power supply: AC110V 60HZ 1A
• Speed accuracy: ±20 rpm
• Package: Carton box

Available Rotors:

The TD4C centrifuge supports various rotor configurations, including 8 x 15 ml, 6 x 10/15 ml, 12 x 5 ml, 12 x 7 ml, and 8 x 10/7/5 ml. Users can select the appropriate rotor based on their specific centrifugal working theory and specialties. The centrifuge is driven by a brushless direct current motor, offering several advantages:

• Digital display for time and speed.
• Electric lock for enhanced safety.
• Simple construction, making it reliable and easy to operate.
• Auto-balance function, which allows users to check tubes at the same level visually instead of weighing them, simplifying the balancing process.

Unpacking:

Upon receiving the centrifuge, users should immediately inspect the package for any serious damage. If damage is found, contact the supplier directly. Otherwise, proceed to unpack the centrifuge, retrieve the instruction manual, and verify all components and accessories against the packing list. Report any missing items promptly.

Installation:

The centrifuge must be installed on a flat, stable surface, such as a table or desk. Ensure all four feet are firmly touching the surface. Connect the power supply to the unit and plug it into a grounded socket to prevent electric shock. (Note: Most European electric sockets are grounded.)

Operation:

1. Check Rotor Nut: Before use, ensure the round nut in the rotor is not loose. If it is, fasten it securely.
2. Prepare Tubes: Prepare the tubes by adding the test liquids. Visually confirm that the liquid levels in opposing tubes are at the same height to ensure balance.
3. Load Tubes: Load the tubes symmetrically onto the tube rack. Improper loading can lead to severe vibration during centrifugation.
4. Close Lid: Close the lid and ensure it is securely locked.
5. Set Parameters:
   • Set Speed: Press the "SEL" button (②) until "A1 ※3100" flickers in the digital window (⑨). Use the speed buttons (③/④) to adjust the speed. The speed range is 0 to 4000 rpm (rotations per minute).
   • Set Time: Press the "SEL" button (②) until "04:39" flickers in the digital window (⑩). Use the time buttons (③/④) to adjust the time. The time range is 0 to 99 minutes.
   • Set Brake (Acceleration and Deceleration): Press the "SEL" button (②) for a few seconds. The time window (⑩) will display "bX". Use the up/down buttons (③/④) to set the brake rate. There are ten possibilities, ranging from slowest (b0) to fastest (b9). The manufacturer typically sets a suitable brake rate (e.g., "b5") before shipping, so users generally do not need to adjust this step.
6. Start Centrifuge: Press the "Start" button (⑥). The "Working indicator" (⑦) will illuminate, and the centrifuge will begin operation. The speed window (⑨) will display the current rpm, and the time window (⑩) will start counting down the remaining time. It takes approximately 1 minute for the centrifuge to reach its maximum speed.
7. Stop Centrifuge: When the centrifugation process is complete, or if the "Stop" button (⑤) is pressed, the time window will display "0". The "Stop indicator" (⑧) will illuminate, and the speed window (⑨) will also show "0".
8. Open Lid: Open the lid and carefully remove the tubes. The centrifugation process is now finished.

Power Off:

Push the switch down to turn off the display panel. The machine will still be on. If the machine will not be used for a long time, unplug it from the wall socket.

Troubleshooting:

If the centrifuge does not operate, first check that the machine is turned on (the top part of the switch is pushed in). Verify the power connection and inspect the fuses within the machine, replacing them if necessary. If the centrifuge still fails to work, contact the supplier. Any unauthorized repair attempts inside the machine will void the warranty.

Quality Warranty:

1. The machine comes with a one-year warranty.
2. Customers will only be charged for parts for repairs on machines older than 12 months.
3. All troubleshooting and maintenance queries will receive a response within 24 hours.
4. After a machine is repaired, a professional technician will file a record and track its usage.
