FUTURA BIOLABS
Everything you need to know about peptide storage and reconstitution — plus our built-in calculator for precise research measurements.
LIVE DEMO
Ready for reconstitution
Equalise vial pressure with sterile needle
Add 1–2 mL bacteriostatic water slowly
Gently swirl — never shake vigorously
Store at 2–8°C up to 8 weeks
RESEARCH TOOL
Enter your peptide vial size and the volume of bacteriostatic water you will add. The calculator returns the final concentration per mL.
For in vitro research use only. All calculations are for research planning purposes only.
STORAGE
−20°C
Freezer Storage
Lyophilised peptides remain stable for up to 48 months. Ideal for long-term preservation.
Best for long-term2–8°C
Fridge Storage
Reconstituted peptides should be stored at 2–8°C and used within 4–8 weeks.
Post-reconstitution20–25°C
Room Temperature
Short-term only during active use. Lyophilised peptides tolerate brief room temp exposure.

Bacteriostatic water is the standard solvent for most peptides. Hydrophobic peptides may require a small amount of acetic acid (0.1% AA) to achieve complete dissolution. Always create a stock solution at higher concentration than needed, allowing for later dilution.
Insert a sterile needle half-filled with air into the rubber stopper before adding solvent. The vial will either draw in or release air, stabilising internal pressure and preventing solution loss through the stopper during subsequent handling.
Gently swirl — never shake vigorously. Vigorous agitation creates foam and can physically damage the peptide structure through mechanical shear. If particles remain after swirling, gentle sonication can assist complete dissolution.
Use between 1–2.5 mL of solvent per vial unless specific studies confirm a higher volume is safe. Excessive dilution compromises peptide integrity and reduces shelf life. Use our calculator above to determine optimal concentration.
For maximum sterility, filter the reconstituted solution through a 0.2 µm sterile syringe filter before use. This removes any potential microbial contamination introduced during the reconstitution process.
Once reconstituted, label the vial with the date and concentration. Store at 2–8°C in a refrigerator. Use within 4–8 weeks. Minimise freeze-thaw cycles — aliquot into single-use vials if the full volume will not be used within a session.
