This centrifuge powers on but the tube connector that attaches the air tube to the gauge is broken (see pictures) and so I am not able to properly test this and I am offering is AS-IS for parts or repair.  I took the bottom panel off to get the pictures.  One screw is missing on both the bottom and back panels (see last 2 pictures).  Everything that is included is shown in the pictures.
