Bio-Rad BioLogic DuoFlow Valves - Manual (Page 4)

Example 3. Fraction Collection.
Placed downstream of a column, the V9-8 or AV9-8 may be used as an eight-place fraction collector either for
separations which generate large volume fractions or separations where a fraction collector is not appropriate.
For this example, 1/16" OD/0.020" ID Tefzel tubing is recommended.
Valve maintenance and repair
Model V9-8 and AV9-8 valves should be rinsed with water following use with aqueous buffers, or 20% ethanol
following use with non-aqueous solutions. Never allow salt solutions to dry inside the valve. For repair of
Model V9-8 and AV9-8 valves, contact your local Bio-Rad office.
