Sterile Technique
Also known as: aseptic technique · sterile handling
The practice of avoiding contamination when reconstituting and drawing from vials — wiping stoppers, single-use needles.
Sterile (aseptic) technique is the set of practices that keep a research vial free of contamination: wiping the rubber stopper with an alcohol swab before every entry, using a fresh sterile needle each time, and not touching needle tips or stopper surfaces.
Even with a bacteriostatic preservative present, poor technique can introduce contaminants that spoil a reconstituted peptide and invalidate research.
Good technique, refrigeration and the use of bacteriostatic water together determine how long a reconstituted vial remains usable.

Reconstitution
The process of dissolving a lyophilised (freeze-dried) peptide in a sterile solvent such as bacteriostatic water before study.
Bacteriostatic Water
Sterile water containing 0.9% benzyl alcohol, the standard solvent for reconstituting peptides so a multi-use vial stays sterile.
Benzyl Alcohol
A mild aromatic-alcohol preservative (typically 0.9%) that makes bacteriostatic water bacteriostatic.
Subcutaneous
Into the layer of fat just beneath the skin — the route most peptide research protocols reference.
