Overview+

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is commonly used in laboratory settings as a solvent or diluent for compatible research materials. The benzyl alcohol helps inhibit microbial growth following repeated access to the container. For laboratory research use only. Not for human or veterinary use.

History+

Preserved diluents have been a laboratory staple for decades, with benzyl alcohol adopted as the preservative of choice because it is effective at low concentrations and compatible with a wide range of peptide preparations. It remains the routine reconstitution fluid referenced in peptide-handling protocols.

Structure & specifications+
CAS #: 7732-18-5
Research findings+

Reference handling literature describes reconstitution volumes, storage temperature, and repeat-draw practice as the main determinants of peptide stability after a vial is opened. Bacteriostatic water is the diluent most often specified in these protocols because the preservative allows multiple withdrawals from a single reconstituted vial under refrigeration.

Key areas of research
  • →Use: Reconstitution of lyophilized research peptides
  • →Composition: Sterile water with 0.9% benzyl alcohol
  • →Format: 10ml multi-draw vial
  • →Storage: Room temperature sealed; refrigerate after reconstitution

Frequently asked questions

What's the actual amount in each vial?+
Each vial contains the labeled mass of lyophilized peptide. Selected sizes appear above the price.
Are additional supplies needed?+
Reconstitution requires bacteriostatic water and appropriate sterile research labware – not included.
How long does a vial last?+
Sealed lyophilized vials are stable at −20°C for 24 months. Once reconstituted, store at 2–8°C and use within 28 days.
Does the product come with instructions?+
Each shipment includes the batch-specific Certificate of Analysis and recommended handling protocol.
What purity level is guaranteed?+
≥ 99% by reverse-phase HPLC (UV-220nm), confirmed via ESI-TOF mass spectrometry.
How should I store these products?+
Store sealed vials at −20°C, protected from light. Reconstituted solutions at 2–8°C.
What are peptides and how do they work?+
Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.
Do these products come with instructions?+
Products from Fast Track Labs are supplied without usage instructions, as they are designated solely for in vitro laboratory research and prohibited by law for human or animal consumption. Any misuse or unlawful application of these products will result in permanent denial of service.
How long do products take to deliver?+
Orders are typically processed and shipped within 24 hours, Monday through Saturday. Delivery times vary by location, but most domestic orders arrive within 3–5 business days. You'll receive tracking information as soon as your order ships.
