DEFINITION · 01
Bacteriostatic Water
Purified water containing 0.9% benzyl alcohol as a bacteriostatic preservative. Used in research and laboratory settings to reconstitute lyophilized compounds, permitting multiple draws from the same sealed vial.
DEFINITION · 02
Benzyl Alcohol
An aromatic alcohol used as a bacteriostatic preservative. The 0.9% concentration in bacteriostatic water inhibits bacterial growth in multi-draw vials. Pharmacopoeia-grade concentration verified per production lot.
DEFINITION · 03
Lyophilized
Freeze-dried. Refers to a compound that has had water removed under vacuum to produce a stable solid powder. Lyophilized research compounds typically require reconstitution in a liquid diluent such as bacteriostatic water before use.
DEFINITION · 04
Reconstitution
The process of adding a liquid diluent to a lyophilized (freeze-dried) compound to return it to a usable liquid form. The concentration of the resulting solution is determined by the diluent volume added.
DEFINITION · 05
Certificate of Analysis (CoA)
A document issued by the manufacturer or testing laboratory that verifies the identity, purity, and concentration of a specific production lot. BAC Water Depot issues a CoA per lot, verified by three independent third-party laboratories.
DEFINITION · 06
ISO 9001:2015
The international standard for quality management systems. ISO 9001:2015 registration means a facility maintains documented manufacturing processes, traceability, and continuous quality controls audited by an independent certification body.
DEFINITION · 07
Borosilicate Glass (Type I)
A low-extractable, chemically inert glass classification used in pharmaceutical and high-grade research packaging. Type I borosilicate minimizes interactions between the container and its contents.
DEFINITION · 08
Lot Number
A unique identifier printed on each vial that ties it to a specific production run. Lot numbers allow buyers to request the matching Certificate of Analysis and trace the vial back to its manufacturing date and testing results.
DEFINITION · 09
Third-Party Testing
Independent verification of a product's identity, purity, and concentration by a laboratory that is not affiliated with the manufacturer. Third-party results carry more weight than self-reported manufacturer testing.
DEFINITION · 10
USP (United States Pharmacopeia)
A scientific nonprofit that establishes quality standards for medicines, foods, and supplements in the US. USP standards for sterile water and benzyl alcohol provide reference specifications referenced by BAC Water Depot's manufacturing.
DEFINITION · 11
Crimp Seal
A tamper-evident closure consisting of a rubber septum capped by a crimped aluminum ring. The crimp seal is applied at the end of the manufacturing process and provides visual verification that the vial has not been previously opened.
DEFINITION · 12
Research Use Only (RUO)
A regulatory designation indicating a product is intended for laboratory research and not for human therapeutic, diagnostic, or veterinary application. BAC Water Depot's bacteriostatic water is sold strictly for RUO.
