This Beckman Coulter Optima MAX-E Ultracentrifuge was removed from a university laboratory where it was surplus to requirements.

The unit is in good, used cosmetic condition but it does have marks from use. The Metal door has some rust spots and marks from age.

Unit powers up as it should but it appears to have a Vacuum issue as it displays 'VAC' in the user messages.

From the manual (not included):

This message appears any time the door is open or the chamber pressure is above 500 microns. The message goes off as soon as the pressure is below 500 microns. If a pressure of 10 microns or less cannot be achieved in 45 minutes, the message reappears. If the pressure goes above 500 microns for more than 20 minutes during centrifugation, the message will begin to flash and the rotor decelerates to a stop. Press to clear the message. Verify that the chamber O-ring is undamaged and properly lubricated. Check for sample leakage, and clean the rotor chamber if necessary (see MAINTENANCE, Section 5). The vacuum pump may have moisture contamination. Leave the instrument on, with the door closed, for about 3 hours (or overnight) to allow the pump to purge itself of moisture. If the VAC message continues to flash when you attempt to restart the run, call Beckman Coulter Field Service.

The temperature has been tested at the minimum 0degC and the maximum of 40degC which it reached without issue.

It does not come with a rotor fitted and we are unable to test the centrifuge function due to the 'VAC' error. You are able to set the speed and start the program but it will not display running speed as there is no rotor is fitted.
