To all,

The J-20 XPI centrifuge in room 252 is fixed.  There are now two working centrifuges- the J-20 XPI and the J-30I in room 254.  These two centrifuges only have one contract, so please use them carefully. 

If you use the centrifuges, please record it in the log.  The speed cannot exceed the maximum, the number on the rotor must match the number on the system display, and don't forget to tighten the rotor until it is stable.  If anything happens, please talk to a safety community member.

Pablo, you can use the J-20 XPI centrifuge on the weekend.

Thanks,
Linda and Casey
