[RASMB] centerpieces for 40% TFE

[Patrick England]

Hello everybody,

Could anybody tell me if it is preferable to use charcoal-filled epon or 
aluminum centerpieces to centrifuge samples containing 40% trifluoroethanol?
The tables I have from Beckman unfortunately do not provide any chemical 
compatibility detail concerning this solvent...

Best regards,
Patrick England
