10ml Bacteriostatic Water

Permagainz 10ml Bacteriostatic Water for Injection is a sterile, non-pyrogenic solution intended solely for laboratory and research use. It is formulated to provide a stable diluent for reconstituting lyophilised peptides and other research compounds within controlled environments.
Each vial contains 10ml of sterile water containing 0.9 % (9 mg/mL) benzyl alcohol as a bacteriostatic preservative, designed to inhibit bacterial growth during multiple withdrawals.

This preparation is manufactured under ISO-certified sterile conditions to ensure consistency, purity, and suitability for analytical or in-vitro applications.

Composition and Characteristics

• Active Ingredient: Sterile Water for Injection (USP/Ph. Eur. grade)

• Preservative: Benzyl Alcohol 0.9 % (9 mg/mL)

• pH Range: 4.5 – 7.0

• Osmolality: Approximately isotonic with physiological solutions

Bacteriostatic Water is widely used by researchers as a diluent for peptide reconstitution, allowing for reproducible concentration preparation in cell-based and biochemical studies. The inclusion of benzyl alcohol provides bacteriostatic properties that help maintain solution integrity for up to 28 days after first puncture, when stored under recommended laboratory conditions.

Purity and Quality Assurance

Each batch of Permagainz Bacteriostatic Water is filter-sterilised and tested for endotoxins, particulates, and microbial contamination to ensure full compliance with international laboratory standards. Production follows Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) guidelines.

All vials are sealed with tamper-evident caps, individually labelled, and accompanied by documentation listing lot number, production date, and expiry date for complete traceability.

Laboratory Handling and Storage

• Store at 20–25 °C (ambient laboratory temperature).

• Keep sealed until use.

• Once opened, store at room temperature in a clean environment and discard within 28 days of first puncture.

• Do not freeze or expose to direct sunlight.

Bacteriostatic Water is designed for multi-dose laboratory use, meaning that researchers may withdraw small, precise volumes for peptide or compound reconstitution using sterile instruments.

All handling must be performed under aseptic conditions, wearing appropriate personal protective equipment (PPE) including gloves, laboratory coats, and protective eyewear.
