Fusinite Verified & Fusinite Lens — how to unlock them

Route 1 — Inertinite Benchmark gives you everything in one selection. Route 2 — combine Package A + Package B to reach the same outcome while adding any other tests your sample needs. Both routes provide Fusinite Verified material verification — confirming your material is genuine pyrogenic biocarbon — and full access to Fusinite Lens interpretive reporting. Individual tests on their own provide data in their category only.
