Sterile diluent with 0.9 percent benzyl alcohol used to reconstitute lyophilised peptides under lab SOPs. Research use only.

Keep lyophilised vials cool, dry, and protected from light. For longer storage, refrigerate or freeze. Minimise temperature swings and freeze-thaw cycles. Research use only.

Correct reconstitution preserves integrity and reduces aggregation or contamination. Follow SOPs. Research use only.

Let vial and solvent reach room temperature for 15 to 20 minutes. Disinfect stoppers. Add 1 to 3 mL bacteriostatic water slowly down the vial wall. Swirl gently. Do not shake. Store at 2 to 8 °C. Use the Bluewell Peptide Calculator for planning. Research use only.

Bacteriostatic water is standard for multi-withdrawal vials. Sterile Water for Injection is for immediate single-use preparations. Some labs use dilute acetic acid per SOP for difficult dissolutions. Research use only.

• Freezer, about −20 °C, long term.
• Fridge, 2 to 8 °C, medium term, sealed.
• Room temperature, short handling only.
• Keep sealed and away from light and moisture.

Refrigerate at 2 to 8 °C. For longer horizons, aliquot and freeze to avoid repeat freeze-thaw. Use a suitable cryoprotectant if freezing. Research use only.

Refrigerated solutions are often used within 3 to 6 weeks, with 4 weeks a practical limit in many labs. Frozen aliquots last longer per protocol. Research use only.

• Using tap or boiled water.
• Shaking or vortexing.
• Skipping temperature equilibration.
• Reusing needles or over-puncturing stoppers.
• Repeating freeze-thaw on one vial.

Yes. Every batch has a COA with identity and purity data. View COAs on product pages or the Lab Certificates page. Research use only.
