BACTERIOSTATIC WATER FAQ
Where can I buy bacteriostatic water?
Bacteriostatic water is for sale from Blank Peptides in 10ml vials, with a Hospira 30ml for higher-volume work. It is the solvent most people pair with lyophilized research peptides, so it is stocked alongside the rest of the catalogue rather than treated as an afterthought. Processing time is within 1 business day, shipping from inside the USA.
What is bacteriostatic water, and how is it different from sterile water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. That preservative is what allows a vial to be entered more than once without supporting bacterial growth. Plain sterile water has no preservative and is single-use only, which is why multi-draw laboratory work almost always calls for the bacteriostatic version.
How much bacteriostatic water do I need per peptide vial?
Our catalogue standard is 1mL per 10mg of peptide, capped at 3mL per vial. A 10mg vial takes 1mL, a 20mg takes 2mL and a 30mg takes 3mL, all landing at 10mg/mL. GHK-Cu at 100mg uses the full 3mL. NAD+ and glutathione sit outside that rule and need larger volumes.
Should I order the 10ml or the 30ml vial?
The 10ml covers roughly ten standard reconstitutions and is the tidier option if you work through a few vials at a time, since it will not sit half full for months after first entry. Bacteriostatic water 30ml is listed separately for high-throughput work, where one stopper serving many reconstitutions matters more.
How many times can a bacteriostatic water vial be used?
The benzyl alcohol allows repeated entry, but every puncture is a chance to introduce contamination. Swab the stopper with alcohol before each draw, use a fresh needle every time, and stop using a vial if the solution ever looks cloudy or has visible particulates. Note the date of first entry on the label.
How should bacteriostatic water be stored?
Room temperature is fine, out of direct sunlight, with the stopper protected. Refrigeration is unnecessary and cold solvent slows peptide dissolution. Keep the vial upright in its box, and once opened track the entry date. Bacteriostatic water is stable for a long stretch unopened, but it does not need to be babied.
Does bacteriostatic water expire after opening?
The preservative loses effectiveness over time and the risk from repeated entries accumulates, so opened vials should not be kept indefinitely. Many laboratories discard a multi-dose vial 28 days after first entry as a working convention. That is a handling practice, not a hard chemical deadline, but it is a sensible one to follow.
Is bacteriostatic water sold for research use only?
The bacteriostatic water Blank Peptides supplies is intended as a laboratory reconstitution solvent for research compounds. It is not sold for human or veterinary administration, and nothing we publish about it constitutes medical guidance. Anyone ordering it is expected to be handling research materials in an appropriate setting.
