Bacteriostatic Water (BAC Water) – Sterile Diluent for Research Use

Bacteriostatic Water (BAC Water) is a sterile, non-pyrogenic solution of water containing 0.9% benzyl alcohol as a preservative. It is widely used in research settings as a diluent or solvent for peptides, hormones, and other compounds that require reconstitution before study.

Unlike sterile water for injection (SWFI), bacteriostatic water contains a bacteriostatic agent, which inhibits the growth of bacteria and allows for multiple withdrawals from a single vial. This makes it especially useful in laboratory environments where precise dosing and repeat access are needed.

Key Features:

Sterile, non-pyrogenic water with 0.9% benzyl alcohol preservative
Designed for reconstitution of peptides and other compounds
Allows multiple withdrawals per vial
Manufactured under strict quality and safety standards

Disclaimer: For laboratory research use only. Not intended for human consumption, injection, or veterinary use.

FAQs

What purity levels are available?

Most peptides we supply are available at high purity levels suitable for research use. For advanced experiments requiring minimal impurities, highly pure peptides (>98%) may be preferred.

Why might my peptide look different from others?

The visual appearance of peptides can vary based on sequence composition, hydrophobicity, and the lyophilization process. Some peptides may look fluffy and white, while others may appear glassy, crystalline, or nearly invisible. Regardless of appearance, every vial is carefully weighed using an analytical balance.

Why does the peptide look invisible in the vial?

Some peptides are delivered in small amounts that may not be visible to the naked eye, may adhere to the vial wall, or may absorb moisture during shipping. Centrifuging the vial and dissolving the powder in solvent ensures full recovery.

How are ATHENYX peptides delivered?

Peptides are delivered in lyophilized powder form (freeze-dried), sealed in vials for stability. This is the standard and most reliable delivery method for research use.

What information is included on the vial label?

Each vial label typically includes the product name, quantity, purity, and lot number. Additional details, such as sequence or molecular weight, may be provided upon request.
