This benchtop microcentrifuge is a compact mini centrifuge for quick spin-downs and micro filtration, available as a 4000rpm model (up to 890xg) or a 7000rpm model (up to 2680xg). Both versions use a DC motor, run on 100V to 240V mains at 20W, and take 0.2, 0.5, 1.5 and 2ml tubes plus PCR tubes. A lid flip switch starts and stops the spin, and the rotor lifts out by hand with no tools.
Features and benefits:
- Two speed models: Mini4000 reaches 4000rpm and up to 890xg, Mini-7K reaches 7000rpm and up to 2680xg, so you can pick the force that suits the job
- Lid flip switch starts the run when the lid is closed and stops it when the lid is opened, a simple one-handed routine for repeat spins
- Tool-free rotor change with a snap-on clamp lock, so swapping between tube rotors takes seconds at the bench
- Accelerates and brakes in seconds, which keeps short spin-downs short
- Quiet running: noise at or below 45dB on the Mini-7K and 50dB on the Mini4000, with low vibration
- Small footprint of 156 x 166 x 117mm on the Mini4000, easy to leave on a crowded bench
- Continuous operation with a DC motor, no set run-time limit
Applications:
- Quick spin-downs of 0.2, 0.5, 1.5 and 2ml tubes
- Micro filtration and tube clean-up steps in the laboratory
- PCR tube and PCR 8-strip spinning in molecular biology benches
- Teaching labs and school science departments
- Research and routine bench work needing a small low-speed unit
In the box:
The Mini-7K is shown with an interchangeable round rotor, a PCR long rotor and rotor adaptors. Check the option you choose for the exact rotor set.
Note: Keep the lid closed while the rotor is turning, load tubes in balanced opposite pairs and use tubes rated for the speed you select. The plug options are EU or US type; for UK sockets use a suitable adapter.

Classification: Laboratory centrifuge. Q: What is a microcentrifuge used for? A: A microcentrifuge spins small tubes at modest speed for quick spin-downs and micro filtration. This one takes 0.2, 0.5, 1.5 and 2ml tubes and PCR tubes.. Q: What is the difference between the Mini4000 and the Mini-7K? A: The Mini4000 runs up to 4000rpm and 890xg with a 50dB noise level, while the Mini-7K runs up to 7000rpm and 2680xg at 45dB or less.. Q: Can I change the rotor without tools? A: Yes, the rotor lifts out by hand and locks back in with a snap-on clamp design, so no tools are needed.. Q: How do I start and stop the centrifuge? A: Close the lid to start the spin and open it to stop. The lid flip switch handles both.. Q: How loud is a mini centrifuge like this? A: The Mini-7K is rated at 45dB or less and the Mini4000 at 50dB, with low vibration during the run..
