Description

Bacteriostatic water 10mL from Prime Peptides is sterile water with 0.9% benzyl alcohol in a sealed 10mL vial, the diluent most labs use to dissolve freeze-dried peptides. One vial is enough to reconstitute several peptide vials. Prime Peptides supplies it for in-vitro research only.

What bacteriostatic water is and why labs use it

A freeze-dried peptide arrives as a dry cake of powder. Before you can measure it, it has to be dissolved in a clean liquid that won’t react with it. Plain sterile water is fine for a single draw, but a vial that gets punctured again and again needs protection against bacteria.

That is the job of the 0.9% benzyl alcohol. It slows bacterial growth, so a multi-use vial of peptide solution can sit in the fridge for several weeks without spoiling.

Stability in solution depends on pH, temperature and contamination. If your lab writes its own handling rules, this PubMed search on peptide stability in solution from the National Library of Medicine collects the published work.

How to use Bacteriostatic water 10mL

Swab the stoppers of the water vial and the peptide vial with alcohol.
Draw the volume you need with a sterile syringe.
Run it slowly down the inside wall of the peptide vial.
Swirl gently until the powder dissolves. Don’t shake.
Write the concentration and date on the vial, then refrigerate.

Work out the concentration before you start: milligrams in the vial divided by millilitres added. A 10mg vial with 2mL added gives 5mg per mL.

Peptides you can reconstitute with it

Every freeze-dried vial in our research peptides arrives as powder and needs a diluent, so most customers add one or two vials of water to each order. Every category is linked from the Prime Peptides home page.

How much water to add

There’s no single correct volume. Less water gives a stronger solution and a smaller amount to measure each time. More water gives a weaker solution that’s easier to measure accurately with a small syringe. Most labs pick the volume that turns their target amount into a round number.

BPC-157 10mg: 10mg vial, 2mL added gives 5mg per mL
TB-500 10mg (Thymosin Beta-4): 10mg vial, 2mL added gives 5mg per mL
Tesamorelin 10mg: 10mg vial, 2mL added gives 5mg per mL
Semax 10mg: 10mg vial, 2mL added gives 5mg per mL

A 10mL vial covers about three to five peptide vials at 2 to 3mL each, depending on the volumes your protocol calls for.

Storing Bacteriostatic water 10mL

Keep sealed vials at room temperature, out of direct light. After the first puncture, store the vial in the fridge and use a new sterile needle for every draw. Most labs discard an opened vial after about 28 days.

Throw out any vial that looks cloudy or has particles in it. Good bacteriostatic water is completely clear.

Common reconstitution mistakes

Spraying water straight onto the powder, which foams and can damage the peptide.
Shaking the vial instead of swirling it.
Forgetting to label the concentration and date.
Leaving a mixed vial on the bench at room temperature.
Reusing a needle between the water vial and different peptide vials.
