Common laboratory waters and solvents used with peptides:
- Sterile water: water with no preservative. It’s single-use, because once the vial is opened nothing stops bacterial growth.
- Bacteriostatic water: sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth so the vial can be accessed several times.
- Sterile saline (0.9% sodium chloride): isotonic salt solution, sometimes used where a salt-balanced solution is needed.
- Bacteriostatic saline: saline with 0.9% benzyl alcohol added.
- Dilute acetic acid (around 0.6–1%): used for peptides that don’t dissolve well in neutral water.
- Ultrapure (Type I) water: highly purified, deionised water used for analytical work such as HPLC, not necessarily sterile.

Sed facilisis, leo id sodales malesuada, magna turpis volutpat leo, ut consectetur odio lorem sed ex. Quisque tincidunt magna et lorem maximus semper. Curabitur ultrices libero at consectetur posuere. Vestibulum eget nisi consequat, sodales nulla mattis, convallis quam. Nunc vitae risus scelerisque, suscipit nibh nec, consectetur lorem.
Quisque metus metus vulputate ut rutrum
Maecenas facilisis egestas lacus, eu pulvinar nunc varius dapibus. Nunc velit nulla, vestibulum vitae volutpat sed, ultrices id nisi. Fusce id tristique ipsum. Nunc tincidunt mi in dui tincidunt, at maximus ipsum consequat. Cras nec dolor feugiat, ultrices leo nec, posuere tortor. Pellentesque commodo tortor eget rutrum eleifend.
