Reconstitution Solution (BAC)

Reconstitution solution 10mL vials (bacteriostatic water)

Our reconstitution solution 10mL vials contain bacteriostatic water: sterile water with 0.9% benzyl alcohol, supplied for laboratory research. It is sold in packs of 2, 5 or 10 vials, for 20mL, 50mL or 100mL in total, and it is the diluent labs most often use when reconstituting freeze-dried peptides in a research setting. If you are looking for bacteriostatic water for sale alongside a peptide order, this is the listing to add.

What is bacteriostatic water?

Bacteriostatic water, usually shortened to BAC water, is sterile water with a small amount of benzyl alcohol added as a preservative. Without that preservative, a punctured vial would offer no protection against contamination introduced during later access. Benzyl alcohol inhibits the growth of most bacteria, so a vial can be accessed more than once with sterile technique, where plain sterile water is intended for a single draw. In the lab, BAC water is used to dissolve lyophilized material such as GLP-3 retatrutide 24mg vials, MOTS-c 10mg peptide vials or tesamorelin 10mg research vials. The benzyl alcohol content is fixed on the label; it is not a substitute for sterile water where a protocol calls for a preservative-free diluent, so check the method before choosing.

BAC water 10mL price and pack sizes

• 2 vials × 10mL = 20mL pack
• 5 vials × 10mL = 50mL pack
• 10 vials × 10mL = 100mL pack

The price per mL falls as the pack size rises, so the 10-vial pack is the most economical choice for labs reconstituting several peptides; live pack prices are shown above. As a rule of thumb, plan on having an unopened vial on hand for each peptide you intend to prepare, since opened vials are best kept for a limited period.

Buy BAC water with your peptide order

Adding a reconstitution solution 10mL pack to the same order as your peptides keeps everything on one shipment from our US storefront, so the diluent and the vials it will be used with arrive together. Peptide Partners runs independent third-party testing across its catalog and keeps certificate records by batch in the Certificates tab. Checkout accepts CashApp, Apple Pay, Chime and cryptocurrency, as described in our payment options. Free-shipping eligibility is calculated in the cart, and the shipping policy covers dispatch, full refunds on orders cancelled before shipment, and photo reports of damaged or incorrect items within 48 hours of delivery.

Reconstitution Solution (BAC) FAQ

What is bacteriostatic water?

Bacteriostatic water is sterile water containing a small amount of benzyl alcohol as a preservative. The benzyl alcohol inhibits bacterial growth, which allows a vial to be accessed more than once with sterile technique. Peptide Partners sells it in 10mL vials for laboratory research use only.

Is BAC water the same as sterile water?

No. Both start as sterile water, but BAC water also contains benzyl alcohol, which makes it suitable for vials that will be accessed repeatedly. Plain sterile water has no preservative and is meant for a single use. Check your protocol, since some methods require a preservative-free diluent.

What pack sizes is bacteriostatic water for sale in?

The reconstitution solution comes in 10mL vials sold in packs of 2, 5 or 10, which is 20mL, 50mL or 100mL in total. The price per mL is lowest on the 10-vial pack, and live prices for each pack are printed on the product page.

What is BAC water used for in the lab?

Labs use it to reconstitute lyophilized, freeze-dried peptides before research use, for example retatrutide, MOTS-c or tesamorelin vials. Because it contains a preservative, a single 10mL vial can serve several accesses when handled with sterile technique and kept refrigerated after opening.

How should unopened BAC water vials be stored?

Keep sealed vials at a cool, stable room location away from direct light, in their carton until needed. Once a vial’s stopper has been punctured, refrigerate it, label it with the opening date and continue to handle it with sterile technique for every access.
