Centrifuge Machine

Description

WHAT’S IN THE BOX
1 × Classim C6-4K-20ML Centrifuge unit
• 1 × Power cord
• 1 × Angle rotor (pre-installed), 6 × 20 ml tube capacity
• 1 × Rotor lid key / spanner
• 1 × This Insert & Warranty Card set
GETTING STARTED
1. Place the unit on a flat, stable, level surface with at least 10 cm of clearance on all sides.
2. Open the lid, confirm the rotor is seated and screwed down securely, and load sample tubes in balanced, opposite pairs.
3. Close the lid firmly until it latches. The centrifuge will not start, and will not allow the lid to be opened, while the rotor is spinning.
4. Connect the power cord to a properly earthed AC 220V socket and switch ON at the power switch.
5. Set the desired run TIME using the left dial and the desired SPEED using the right dial.
6. Always balance tubes in opposite pairs before every run.
7. Stay near the unit during the run. Allow the rotor to come to a complete stop before opening the lid.

IMPORTANT SAFETY WARNINGS
• NEVER open the lid while the rotor is spinning or coasting down. Wait for a complete stop.
• ALWAYS balance tubes — load samples of equal volume and weight in opposite, paired positions. Never run with a single, unbalanced tube.
• NEVER exceed the rated tube capacity (20 ml) or the maximum rated speed (4000 rpm) for the installed rotor.
• DO NOT operate the unit with a damaged power cord, cracked rotor, or cracked lid. Stop use and contact support.
• DO NOT use with flammable, corrosive, explosive, or radioactive materials, or in a flammable-gas environment.
• DO NOT move, tilt, or unplug the unit while the rotor is in motion.
• KEEP hands, hair, jewellery, and loose clothing away from the rotor chamber at all times.
• ENSURE the unit is earthed (grounded) before connecting power. Do not use with a frayed or spliced cord.
• DO NOT let children operate this equipment. For use by trained laboratory personnel only.
• DISCONNECT power before cleaning, servicing, or moving the unit.
CARE & MAINTENANCE
• Wipe the exterior and rotor chamber with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Clean up any spilled sample immediately to prevent corrosion of the rotor and chamber.
• Inspect tubes and rotor cavities periodically for cracks; discard any damaged tubes before use.
• Store in a dry, dust-free location when not in use.
TROUBLESHOOTING
Problem Likely Cause & Fix
Unit does not power on Check the power cord is fully seated and the wall socket is live. Confirm the POWER switch is set to ON. Check the fuse in the power inlet.
Lid will not open after a run This is normal if the rotor has not fully stopped. Wait 30–60 seconds after the rotor noise stops, then try again.
Lid will not close / will not latch Check the rotor is seated correctly and not obstructing the lid. Remove and reload tubes if misaligned.
Excessive noise or vibration Switch off immediately. Re-check that tubes are balanced in opposite pairs and of equal volume. Confirm the rotor screw is tight.
Centrifuge stops mid-run An imbalance safety cut-out may have triggered. Switch off, rebalance the tubes, and restart.
Speed does not reach the set value Allow the full run — the unit ramps up gradually. If it still under-speeds, the unit may need servicing.
Burning smell or smoke Switch off and unplug immediately. Do not use again until inspected by an authorised service technician.
