“Your Safer Source for Science”
ACETIC ACID continued
Please consider buying PVC (polyvinyl chloride)–coated acid
bottle—Flinn Plas-PakTM.
*Acetic acid is exactly as described under catalog number A0006
but in a PVC-coated bottle. In the event of breakage, acid and glass shards are retained in a PVC outer envelope. The PVC-coated bottle is a safer package choice.
