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. It continues to provide reliable high speed centrifugation at
low temperatures just as good as the newer models.

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, scratches, and small bits of plastic chipped off
the lid. That’s it. Nothing out of the ordinary.

Thoroughly 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 -4°C during operation at 20,000
rpm and at -20°C during operation at 15,000 rpm.

The following tests and services were performed:

- Door latch tested and working
