How do I store qEV columns?
The presence of a bacteriostatic agent (e.g. <0.05% w/v sodium azide) allows unused qEV columns to be stored and shipped at room temperature.
Unused qEV columns can be stored at room temperature. Used qEV columns can be stored at room temperature providing they have been cleaned according to the instructions in the relevant qEV user manual and stored in 20% ethanol or 0.05% w/v sodium azide. If the appropriate solutions are not available for storage at room temperature then columns can be stored at +4 to +8 °C after use.
