What preservative is in the qEV column storage buffer?

 qEV columns are shipped in a buffer solution that contains <0.1% ProClin™ 200 as a preservative. The preservative keeps the column free from microbial growth during storage.

The ProClin™ 200 concentration is below the level that triggers a hazard classification, so qEV columns do not meet the criteria for an SDS, and Izon does not issue one.
