FAQ — AquaPure Labs Bacteriostatic Water

Question 1

What is bacteriostatic water?

Accepted Answer

Bacteriostatic water is sterile water for injection that contains 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits the growth of most bacteria, allowing the vial to be accessed multiple times without contamination — making it the standard solvent for peptide and hormone reconstitution in research settings.

Question 2

Why 0.9% benzyl alcohol?

Accepted Answer

0.9% benzyl alcohol is the established concentration for bacteriostatic preservation. It is sufficient to inhibit microbial growth across repeated vial punctures while remaining compatible with the majority of peptides and research compounds. Higher concentrations can degrade sensitive peptides; lower concentrations may not provide adequate preservation.

Question 3

What is the purity level of AquaPure water?

Accepted Answer

AquaPure Bacteriostatic Water is produced to 99.9% purity using water for injection (WFI) grade base. Every batch is independently tested for sterility, endotoxins, and benzyl alcohol concentration before release. A Certificate of Analysis is available for each production batch.

Question 4

Is AquaPure water the same as sterile water for injection?

Accepted Answer

No. Sterile water for injection (SWFI) contains no preservative and is intended for single use only. Bacteriostatic water contains 0.9% benzyl alcohol, which allows the vial to be used multiple times over an extended period. For peptide reconstitution requiring repeated access, bacteriostatic water is the appropriate choice.

Question 5

Can I use AquaPure water with any peptide?

Accepted Answer

AquaPure Bacteriostatic Water is compatible with the vast majority of research peptides. However, some highly sensitive peptides may require acetic acid solution or sterile saline for reconstitution. Always consult the technical data sheet for the specific compound you are working with. AquaPure products are for research use only.

Question 6

How should I store bacteriostatic water?

Accepted Answer

Store at room temperature (15–25°C) away from direct light and heat. Once opened, bacteriostatic water can be stored and used for up to 28 days. Do not freeze. Keep vials in their original packaging until use to maintain sterility and protect from light degradation.

Question 7

How long does an opened vial remain usable?

Accepted Answer

An opened vial of AquaPure Bacteriostatic Water remains usable for up to 28 days when stored correctly at room temperature and accessed using aseptic technique. Always inspect the vial before use — discard if you observe particulate matter, cloudiness, or any sign of contamination.

Question 8

What aseptic technique should I use when drawing from the vial?

Accepted Answer

Always use a new, sterile needle and syringe for each draw. Wipe the rubber stopper with a 70% isopropyl alcohol swab and allow it to dry before puncturing. Work in a clean environment and avoid touching the needle or stopper. Proper aseptic technique is essential to maintaining the integrity of the vial across multiple uses.

Question 9

Can bacteriostatic water be frozen?

Accepted Answer

No. Freezing is not recommended. Freezing can cause the benzyl alcohol to separate from the water phase and may compromise the sterility and integrity of the vial seal. Store at room temperature as directed.

Question 10

What pack sizes are available?

Accepted Answer

AquaPure Bacteriostatic Water is available in three pack sizes: 1 Vial (£12.99), 5 Vials (£59.99), and 10 Vials (£109.99). Each vial contains 10ml of bacteriostatic water with 0.9% benzyl alcohol.

Question 11

How is the product packaged for shipping?

Accepted Answer

Each vial is individually sealed with a tamper-evident cap and shipped in protective packaging designed to prevent breakage in transit. Orders are dispatched in plain, discreet outer packaging with no product branding visible externally.

Question 12

Do you ship internationally?

Accepted Answer

Currently we ship within the United Kingdom. International shipping options are under development. If you have a specific international enquiry, please contact us directly.

Question 13

Can I obtain a Certificate of Analysis for my order?

Accepted Answer

Yes. A Certificate of Analysis (CoA) is available for every production batch. If you require a CoA for your records, please contact us with your order number and we will provide the relevant documentation.

Question 14

Is AquaPure water safe for human use?

Accepted Answer

AquaPure Bacteriostatic Water is manufactured and sold strictly for research and laboratory use. It is not intended for human injection, therapeutic use, or consumption. It must only be used by qualified researchers and professionals in appropriate laboratory settings.

Question 15

What regulations govern bacteriostatic water in the UK?

Accepted Answer

In the United Kingdom, bacteriostatic water for research use is not classified as a medicinal product when sold for laboratory purposes. However, it must be manufactured to appropriate quality standards. AquaPure products are manufactured in GMP-aligned facilities with full batch documentation. Purchasers are responsible for ensuring their use complies with all applicable local regulations.

Question 16
