[RASMB] condensation

[Chad Brautigam]

Dear All,

We're having a serious problem with our XL-I.  The UV filter that is  
positioned over the condenser lens is fogging with oil every time it  
is used.  It is the underside of the filter that gets fogged.   
Fogging, of course, completely negates our ability to use the  
interference optics.  A Beckman service rep recently changed the  
condenser lens and also replaced our vacuum pump.  Does anyone have  
any notion of why this fogging is occurring and what the fix might  
be?  Our service rep is trying hard to get this fixed, but he is new  
to the analytical centrifuges.  Any help the community can offer  
would be greatly appreciated.

Chad
