Purity Laboratories

What Purity Laboratories does

Purity Laboratories, Inc. is an independent analytical testing laboratory founded in 1970 and headquartered at a 20,000 sq. ft. facility in Lake Oswego, Oregon. The company performs environmental and clinical testing of food, water, dietary supplements, nutraceuticals, pharmaceuticals, and environmental samples, with method coverage spanning microbiology (pathogens, APC, coliforms, yeast and mold), chemistry (nutrition, water/wastewater, trace metals), allergens, identity testing, USP 467 residual solvents, heavy metals, and pesticides and toxic compounds. Core instrumentation is mass spectrometry - ICP-MS for metals at parts-per-trillion detection limits, GC-MS and LC-MS for pesticides, residual solvents, and identity work - supplemented by plating microbiology and RT-PCR for SARS-CoV-2 surface testing. The lab is accredited to ISO/IEC 17025:2017, CLIA-certified as a high-complexity clinical laboratory (since September 2013), and meets AOAC ALACC guidelines.

The business operates a dual go-to-market. The primary model is sales-led B2B testing: customers submit Chain of Custody samples via mail, courier, or drop-off, receive quote-based pricing for most assays, and obtain reports through an online portal, email, fax, or mail, with rush surcharges of 50% (5-day) and 100% (next-day) on top of standard 5-10 business-day turnarounds. The secondary model is self-serve e-commerce for surface testing products - Covid-19 kits ($100 single test up to $900 for 12 tests), total bacteria tests ($22 each), and mold tests ($22 each) - with weekly, monthly, and quarterly subscriptions at up to 25% discounts. Differentiation rests on the proprietary Gold Seal certification program (220 to 900+ toxic compound screens), the exclusive P2i prenatal/infant testing program run with The Forum, and 55-plus years of regional reputation. Purity is privately held, parented by K & D Laboratories, with no disclosed external institutional investment or PE/VC backing.
