Research access

Pricing sits behind an account.
Certificates never will.

Suppliers in this category get de-platformed for publishing open, indexable price lists, so the catalog is gated. Registration is free, takes about a minute, and access is immediate — no approval queue, no minimum order, no purchase required. All 35 lot certificates stay public regardless.

  • An independent certificate on every lot

    HPLC purity, mass-spec identity, endotoxin, heavy metals and water content — tested by Janoshik Analytical, published before the lot goes on sale.

  • One price, no coupon theatre

    Registered pricing is the price. Volume discounts apply automatically: 5% from 5 vials, 10% from 10 vials, 15% from 25 vials.

  • Same-day dispatch from US stock

    Orders with cleared payment before 2 pm CT leave the same business day, gel-packed in insulated mailers.

  • A recall list that actually works

    Lot notices are a separate list from marketing. Unsubscribing from one never removes you from the other.
