Reliable Floor Centrifuge in Good Condition for your Lab

This centrifuge has been proven time and time again through many years of service and it still hasn’t quit. Over the years it has developed a few minor cosmetic flaws, but none of it affects the performance. The rotor chamber has some small spots of discoloration and the centrifuge exterior has some scuffs and scratches, but that’s it -- nothing out of the ordinary.

Inspected and Tested by Technical Staff

Our technical staff inspected and tested this centrifuge, confirming it functional and guaranteeing it to hold a steady low temperature during operation at top speeds. The refrigeration system holds the rotor chamber at -12°C during operation at 15,000 rpm. It is configured for 208V power.

The following tests were performed:

- Tested centrifuge to 21,000 rpm without issue: PASSED
- Tested refrigeration during 15k RPM run, holding at -12°C: PASSED
- Tested lid lock and unlock: PASSED
- Tested rotor accel/decel: PASSED
- Tested control panel and display: PASSED

Recharged Refrigeration System

To ensure the refrigeration is reliable, our technician performs a full evacuation of the refrigeration system and refills it with new refrigerant. The recharge process involves the following:

- Vent system of refrigerant
- Apply 250-micron vacuum to test for leaks, remove debris, and boil off moisture in lines
- Nitrogen purge three times to clear lines for preventative maintenance
- Refill system with new refrigerant
