Product Description
Hydrochloric Acid, 34-37% OMNITRACE®, 500ML
MilliporeSigma OmniTrace Hydrochloric Acid, 34-37% | Trace Element Analysis Grade
When trace metal contamination ruins a sample, no amount of reanalysis fixes the problem. If you're doing ICP-MS, ICP-OES, digestions, or any sample prep where sub-ppb metal levels matter, your acid is everything. OmniTrace Hydrochloric Acid from MilliporeSigma is tested to parts-per-billion levels and packaged in FEP PTFE bottles specifically chosen to protect purity from container to lab bench. This is the acid that disappears into your blank -- exactly where it belongs.
And yes, we ship it to your door with NO hidden fees. No hazmat surcharges despite the UN1789 classification, no handling fees, no surprise line items on your invoice. Just the acid, free ground shipping, and a clean transaction!
