What RNA elution volumes are available with the QIAsymphony RNA Kit?
FAQ ID -1943

RNA processed on the QIAsymphony SP with the QIAsymphony RNA Kit can be eluted in 200, 100, or 50 µl.

Elution in smaller volumes will provide higher concentration, but lower overall yield. Total RNA yield with elution in 50 µl will be about 20% lower compared to elution in 100 µl.
