Bacteriostatic Water (BAC Water) is a critical laboratory supply used in peptide and compound research. In Colombia, however, researchers and clinics often report difficulty sourcing consistent, sterile, lab-grade BAC water.
This guide explains what BAC water is, why it can be difficult to find locally, and what researchers should look for when sourcing it in Colombia.
What Is Bacteriostatic Water?
Bacteriostatic Water is sterile water containing a small concentration of benzyl alcohol (typically 0.9%), which inhibits bacterial growth after vial puncture.
In research settings, BAC water is commonly used for:
- Reconstitution of research peptides
- Dilution of lyophilized compounds
- Multi-use laboratory protocols requiring sterility
All uses described here refer strictly to laboratory research applications.
Why Is BAC Water Hard to Find in Colombia?
Unlike pharmaceutical saline or sterile water, bacteriostatic water is not widely stocked in Colombian retail pharmacies. Availability is limited due to:
- Low commercial demand outside research environments
- Import restrictions on multi-use sterile solutions
- Regulatory classification differences between medical and research supplies
As a result, many laboratories rely on specialized research suppliers rather than traditional medical distributors.
BAC Water vs Saline vs Sterile Water
While these solutions may appear similar, they serve different roles in laboratory workflows:
- Bacteriostatic Water: Contains benzyl alcohol to inhibit bacterial growth after opening
- Sterile Water: No preservatives; intended for single-use protocols
- Saline: Contains sodium chloride; used for different experimental contexts

What to Look for When Buying BAC Water in Colombia
When sourcing bacteriostatic water for laboratory research, consider the following:
- Sterility assurance and sealed packaging
- Clear labeling for research use only
- Appropriate vial size for laboratory workflows
- Reliable local availability to avoid interruptions
