Resources

Working tools for the bench.

A reconstitution calculator, a storage quick-reference, a sample Certificate of Analysis, and the compliance documents your institution will ask for. Built for qualified researchers, not end-users.

Tool 01

Reconstitution calculator.

Enter the vial mass and the bacteriostatic water volume you're adding. The calculator returns the concentration per milliliter and a 10 IU syringe-reading guide for common measurement contexts. Research use only.

Tool 02

Storage & stability quick reference.

Default storage parameters for lyophilized and reconstituted peptides. Check your specific compound's COA for lot-specific notes.

Lyophilized
Desiccated, light-protected
Default lyophilized research peptide storage. Protect from moisture and light. Stable for years under these conditions.
−20°C freezer
Reconstituted (short)
Refrigerated, sealed vial
Once reconstituted, store sealed in bacteriostatic water. Typical stability window: 7–30 days depending on compound.
2–8°C fridge
Reconstituted (long)
Aliquoted, single-use freeze
Aliquot into single-use portions and freeze. Avoid freeze-thaw cycles. Label each aliquot with lot ID and prep date.
−20°C freezer
Shipping
2-day ground, USA
Orders leave the warehouse within 24 business hours via 2-day carrier. Lyophilized peptides remain stable at ambient for typical transit. Insulated cold-chain packaging is available on request for climate-sensitive destinations or compounds.
2-day USA
Do not
Avoid
Repeated freeze-thaw cycles · UV exposure · Moisture on lyophilized powder · Long storage at room temperature · Reconstitution with non-bacteriostatic water for multi-day use.

Lot-specific storage notes override defaults — check each compound's COA.

Tool 03

Institutional document library.

What procurement asks for. All documents available on request — email sales@piqbio.com and we'll send the current revisions.

  1. 01

    Sample Certificate of Analysis

    A complete sample COA showing the full panel: identity (HPLC + MS), purity, sterility (USP <71>), endotoxin (LAL), lot ID, and the signing laboratory. See the Evidence page for the live preview.

  2. 02

    W-9 on request

    For institutional purchase orders and NET-30 wholesale accounts. Sent within one business hour during our operating window.

  3. 03

    Research Use Only statement

    One-page compliance document for institutional files. Confirms PiqBio products are sold exclusively as research chemicals, not for human or animal consumption, not FDA-approved.

  4. 04

    Lot number verification · Q2 2026

    Once the COA Library opens in Q2 2026, any lot number on a PiqBio vial will return its signed analytical panel from our public library. No account required.

  5. 05

    Shipping protocol summary

    2-day ground carrier default, 24-hour dispatch window, plain/discreet packaging. Optional insulated cold-chain upgrade spec on request — useful for institutions with cold-chain audit requirements.

  6. 06

    Reconstitution notes per compound

    Compound-specific reconstitution, solvent compatibility, and short-term stability notes. Available on request for any compound in our current catalog.
