Hello List Members,
=A0
We have been using a Fluor/Away High volume filtration setup for filtering 
low concentration aqueous ethidium bromide solutions for many years without
 any issue.=A0 Within the past year we have experienced a series of filter 
failures whereby the carbon media somehow breaks through and is discharged 
through the effluent side of the filter.=A0 The supplier did follow up with
 a replacement filter the first time it was reported but could offer no rea
son.=A0 I have just experienced the same problem again and am wondering if 
anyone else=A0that uses this system is experiencing the same problem.=A0 
=A0
I would also be interested in alternate EtBr disposal solutions that others
 may be utilizing.=A0

Sincerely,

Hello List Members,


 


We have been using a Fluor/Away High volume filtration setup for filte
ring low concentration aqueous ethidium bromide solutions for many years wi
thout any issue.  Within the past year we have experienced a series of
 filter failures whereby the carbon media somehow breaks through and is dis
charged through the effluent side of the filter.  The supplier did fol
low up with a replacement filter the first time it was reported but could o
ffer no reason.  I have just experienced the same problem again and am
 wondering if anyone else that uses this system is experiencing the sa
me problem.  


 


I would also be interested in alternate EtBr disposal solutions that o
thers may be utilizing. 


 


Sincerely,


 


Anthony Santoro
