Buying guide: Which solvent? Bacteriostatic, sterile and acetic acid water compared
What is bacteriostatic water?
Bacteriostatic water is purified water with benzyl alcohol added as a preservative. The benzyl alcohol slows the growth of bacteria, which is why it is the usual choice when a sealed vial will be opened and drawn from more than once. In the laboratory it is used to reconstitute (dissolve) freeze-dried research peptides.
Bacteriostatic water specifications
- Product: bacteriostatic water (water with benzyl alcohol preservative)
- Vial sizes: 3ml and 10ml
- Pack: box of 10 vials
- Catalogue codes: BA03 (3ml), BA10 (10ml)
Choosing a solvent
- Bacteriostatic water contains a preservative; sterile water does not, so it is normally used once per vial.
- Acetic acid water is a slightly acidic solvent used for peptides that dissolve poorly in neutral water.
- Browse all research peptides to reconstitute.
