Laboratory safety
Are research peptides safe to handle in the lab?
This page covers laboratory safety only: how to handle, store and dispose of lyophilised research peptides, and how contamination and heat exposure compromise material. These compounds are supplied strictly for laboratory research use.
Research use only. Not for human or veterinary use. Buyers must be 21 or older.
Scope of this page
Research peptides are laboratory reagents. "Safe" here means handled in a way that protects the person at the bench and preserves the integrity of the material.
Everything we supply is a laboratory reagent for in-vitro research, and our support covers lab handling, storage and documentation only.
Safe handling practice
- Standard laboratory PPE. Gloves, eye protection and a lab coat, as for any fine powder reagent. Avoid generating dust when opening vials.
- Aseptic technique on reconstitution. Wipe the septum, use fresh sterile transfer equipment, and let the solvent run down the vial wall rather than jetting onto the powder.
- Single-use consumables. Never reuse transfer equipment between vials. Cross-contamination is the most common way a good batch is spoiled.
- Label everything immediately. Compound, batch code, concentration and reconstitution date on every vial and aliquot. Unlabelled solutions have to be discarded.
- Contain spills and breakages. Treat spilled powder or solution as laboratory waste: contain, decontaminate the surface and dispose of the material through your waste stream.
Storage and stability
- Lyophilised, long term. Keep sealed vials at −20 °C or colder, dry and out of light. Short holding periods at 2–8 °C are acceptable.
- After reconstitution. Refrigerate at 2–8 °C and use within a short window; solutions are far less stable than the dry powder.
- Avoid freeze–thaw cycles. Split solutions into single-use aliquots before freezing so nothing is thawed twice.
- Heat, light and agitation. All three degrade peptides. Don't leave vials on a warm bench, don't shake to dissolve, and keep material out of direct light. Our reconstitution guide has the full stability table.
Contamination and disposal
- Bacteriostatic versus sterile water. Bacteriostatic water inhibits microbial growth and suits solutions held for several days; sterile water suits single-session work. Neither makes a contaminated vial safe to keep.
- Sharps go in a sharps bin. Sharps and used lab consumables go into a rigid sharps container, never in general waste.
- Discard anything suspect. Cloudy solution, visible particulate, a compromised septum or an unknown storage history all mean the vial is discarded rather than used.
- Keep records. Batch code, receipt date, reconstitution date and storage conditions per vial make results reproducible and problems diagnosable.
