BAC Water

$10.00

Biostatistic Water, commonly referred to as bacteriostatic or sterile water for injection, is a specially prepared water used in laboratory and clinical research to reconstitute lyophilized (freeze-dried) peptides. It is designed to maintain the sterility and integrity of peptides during reconstitution, storage, and application in research settings.

All peptides offered by Resolve Peptides are produced through the lyophilization (freeze-drying) process, a method that preserves molecular stability during handling and transport for approximately 3–4 months. Once reconstituted with bacteriostatic water, the solution must be stored under refrigeration to maintain integrity, where it generally remains viable for up to 30 days. Lyophilization, also referred to as cryodesiccation, is a specialized dehydration technique in which the compound is frozen and then placed under reduced pressure. This causes the frozen water content to sublimate directly from solid ice to vapor, leaving behind a stable, crystalline peptide powder. The resulting white, porous material can be kept at room temperature until reconstitution is required. After delivery, peptides should be safeguarded from light exposure and stored in a cool environment. For short-term use spanning several days to weeks, refrigeration at or below 4°C (39°F) is recommended. While lyophilized peptides may remain structurally intact at room temperature for weeks, cold storage provides added assurance of stability for ongoing research. For extended preservation lasting months or years, ultra-low freezing is preferred. Storage at –80°C (–112°F) offers the most reliable option for maintaining peptide quality and consistency over long durations. For detailed guidance on peptide handling and storage protocols, please refer to: Peptide Storage Information – 1stPharma.com For extended preservation, particularly for storage spanning multiple months to years, peptides are best kept in ultra-low freezers at approximately –80°C (–112°F). Under these long-term conditions, structural stability is maximized, ensuring peptides retain their quality and suitability for future research applications.

Description

Function & Purpose

The primary function of biostatistic water is to safely dissolve peptide powders without introducing contaminants or destabilizing the peptide chains. Its sterile composition prevents bacterial growth and minimizes peptide degradation, preserving potency and molecular stability.

Chemical Properties

Biostatistic water is ultrapure, non-pyrogenic water that has been filtered and sterilized. Some formulations may contain 0.9% benzyl alcohol as a preservative to extend shelf life after opening. Its pH is generally adjusted to ~5.5–7.0 to ensure compatibility with peptide bonds.

Why It’s Used for Peptides

Peptides are highly sensitive to contaminants and pH imbalances. Biostatistic water is ideal for peptide reconstitution because it:

  • Maintains sterility during multiple withdrawals
  • Prevents bacterial growth (with benzyl alcohol)
  • Is non-reactive with amino acid chains
  • Dissolves peptides quickly and cleanly for research use

Sterility & Storage

Once a vial is opened, the presence of benzyl alcohol in bacteriostatic water allows safe usage for up to 28 days if stored at 2–8°C (refrigerated). Single-use sterile water, by contrast, must be discarded immediately after opening. Always use sterile technique when handling.

Comparison with Other Solvents

Bacteriostatic Water: Contains benzyl alcohol, extends usage to 28 days. Ideal for multiple withdrawals.

Sterile Water: No preservatives; single-use only. Must be discarded after opening.

Acetic Acid (0.6%): Used to stabilize certain peptides like GHRH analogs. May be more acidic.

Sodium Chloride (0.9%): Can be used in specific cases, though compatibility varies by peptide.

Usage Notes

  • Always consult reconstitution instructions specific to each peptide. • Use sterile syringes and alcohol swabs to maintain vial integrity. • Typical reconstitution volumes range from 1 mL to 5 mL depending on peptide concentration requirements.
