Tarr, LLC is one of the largest west coast distributors of commodity and specialty chemicals.

High Purity Chemicals

Only Tarr offers Tera-Clear 1000, an unsurpassed, ultra-pure IPA (isopropyl alcohol) made specifically to meet semiconductor purity requirements.

We start with a system of electropolished stainless steel and PFA Teflon-wetted components in a class 100 cleanroom, then use our proprietary ion exchange process to reduce ionic contaminants to PPT (parts per trillion) levels. Finally, all-Teflon 0.05 m filters remove metallic impurities and particles well below 100 PPT.
