What Is Bac Water?
Bacteriostatic Water, often referred to as Bac Water, is a sterile, non-pyrogenic solution specifically designed for use in peptide reconstitution and dilution. It is widely used in laboratory and research settings where maintaining sterility and precision is essential.
The composition of sterile non-pyrogenic solution is simple but effective: it consists of sterile water combined with 0.9% benzyl alcohol. This small amount of benzyl alcohol acts as a bacteriostatic agent, meaning it inhibits the growth of bacteria. As a result, the solution can be safely used multiple times after opening, provided it is handled correctly.
The primary purpose of Bac Water is to dilute or reconstitute lyophilized (freeze-dried) peptides. Before use, many peptides come in powder form and must be mixed with a sterile liquid to achieve the desired concentration. Bac Water allows researchers to prepare accurate solutions while maintaining product stability.
One of the key reasons sterile non-pyrogenic solution is preferred over regular sterile water is its extended usability. While standard sterile water is typically intended for single use, Bac Water can be stored and reused for a limited period after opening due to its bacteriostatic properties. This makes it more convenient and cost-effective, especially in ongoing research or repeated peptide preparation.
Typical use cases include peptide research, laboratory experiments, and any application requiring precise reconstitution of compounds. Its reliability, sterility, and reusability make sterile non-pyrogenic solution a standard choice for professionals working with peptides.

How Bac Water Is Used with Peptides
Bac Water plays a key role in preparing peptides for use, particularly when working with lyophilized (freeze-dried) compounds. Proper reconstitution ensures accuracy, stability, and safety throughout the process.
Step-by-Step Overview of Reconstitution
- Prepare your materials
Gather the peptide vial, sterile non-pyrogenic solution vial, a sterile syringe, and alcohol swabs. - Clean the vial tops
Wipe both the peptide vial and Bac Water vial stoppers with an alcohol swab to maintain sterility. - Draw Bac Water into the syringe
Using a sterile syringe, draw the required amount of sterile non-pyrogenic solution based on your desired concentration. - Inject Bac Water into the peptide vial
Slowly inject the water into the vial, directing the stream toward the glass wall rather than directly onto the powder to avoid damaging the peptide. - Dissolve the peptide
Gently swirl the vial (do not shake vigorously) until the peptide is fully dissolved.
Importance of Sterile Handling
Maintaining sterility is critical throughout the process. Contamination can compromise the integrity of the peptide and pose safety risks. Always use sterile syringes, avoid touching needle tips, and minimize exposure of vials to open air.
Storage Recommendations After Mixing
- Store reconstituted peptides in a refrigerator (typically 2–8°C)
- Keep vials sealed tightly when not in use
- Avoid repeated temperature fluctuations
- Use within a recommended timeframe depending on the peptide’s stability
Bac Water itself can also be reused (within limits) due to its bacteriostatic properties, but it should still be handled carefully and discarded if contamination is suspected.
Safety Considerations
- Always follow proper laboratory or handling protocols
- Do not use if the solution appears cloudy or contains particles
- Avoid cross-contamination between vials
- Clearly label reconstituted peptides with concentration and date
By following these guidelines, you can ensure accurate peptide preparation while maintaining safety and product integrity.
Bac Water Peptide Dosage Guidelines
When discussing “dosage” in relation to sterile non-pyrogenic solution, it’s important to clarify that Bac Water itself is not dosed. Instead, it is used as a diluent to prepare peptides at a specific concentration. The actual dosage depends on the peptide being used, while sterile non-pyrogenic solution simply determines how concentrated or diluted the final solution will be.
General Principles of Peptide Reconstitution
Reconstitution involves adding a precise volume of Bac Water to a vial of lyophilized peptide to achieve a known concentration. This makes it easier to measure and handle the peptide accurately.
For example:
- If you have a 10 mg peptide vial and add 2 ml of Bac Water, the concentration becomes:
5 mg per 1 ml - If using an insulin syringe (100 units = 1 ml), then:
1 unit = 0.05 mg (50 mcg)
By adjusting the amount of Bac Water added, you can control how much peptide is delivered per unit on the syringe.
Factors Affecting Dilution
Several variables influence how much sterile non-pyrogenic solution should be used:
- Peptide amount (mg): The total quantity in the vial
- Desired concentration: Higher dilution = lower concentration per unit
- Ease of measurement: More diluted solutions allow for more precise dosing
- Peptide stability: Some peptides require specific concentrations for optimal stability
Choosing the right dilution is a balance between accuracy and practicality.
Common Mistakes to Avoid
- Adding too little Bac Water
This results in a highly concentrated solution, making accurate measurement difficult - Adding too much sterile non-pyrogenic solution
Over-dilution can require injecting larger volumes, which may be impractical - Incorrect calculations
Misunderstanding mg-to-ml conversions can lead to inaccurate dosing - Shaking the vial
Vigorous shaking can damage delicate peptide structures—always swirl gently - Poor labeling
Not labeling concentration and date can lead to confusion and errors later
Bac Water Peptide Dosage Guidelines
When working with a 3ml volume of Bac Water, it’s important to understand that Bac Water itself is not “dosed.” Instead, it is used to dilute peptides to a specific concentration, making them easier to measure and handle accurately.
Understanding the Role of 3ml Bac Water
A 3ml addition simply means you are increasing the total liquid volume in the vial, which lowers the concentration of the peptide per unit. This is often preferred for improved precision, especially when working with smaller peptide doses.
General Principles of Peptide Reconstitution
Let’s look at a practical example using 3ml of Bac Water:
- Peptide vial: 10 mg
- Bac Water added: 3 ml
This gives a concentration of:
- 10 mg ÷ 3 ml = ~3.33 mg per ml
If using a standard insulin syringe (100 units = 1 ml):
- 1 unit = 0.033 mg (33.3 mcg)
So:
- 10 units = 0.33 mg (333 mcg)
- 30 units = ~1 mg
This higher dilution allows for finer control when measuring smaller doses.
Factors Affecting Dilution
When choosing to use 3ml of Bac Water, consider:
- Peptide amount: Larger quantities may still remain concentrated even with 3ml
- Desired dosing precision: More dilution = easier micro-dosing
- Injection volume preferences: Higher dilution means larger injection volumes
- Peptide stability: Some peptides are more stable at certain concentrations
Common Mistakes to Avoid
- Assuming Bac Water has a “dose”
It only affects concentration, not the actual peptide amount - Miscalculating concentrations
Always divide total mg by total ml to get mg/ml - Using inconsistent volumes
Adding slightly more or less than 3ml can significantly change dosing accuracy - Overcomplicating dilution
Choose a volume (like 3ml) that makes calculations simple and repeatable - Not labeling the vial
Always note: total mg, ml added, and resulting concentration
Bac Water Pricing in the UK
Understanding pricing is an important part of choosing where to buy Bac Water, especially for ongoing peptide research where repeat purchases are common.
Overview of Available Vial Sizes
In the UK market, Bac Water is typically available in several vial sizes, including 3ml, 10ml, and 30ml, depending on the supplier.
On leolab.co.uk, one of the most common options is a 3ml vial, designed for standard peptide reconstitution needs and convenient single-use projects.
Buy Bac Water: Pick the Right Vial
Any peptide, including Bac Water, should be used within 4 weeks (ideally) and no longer than 6 weeks, as its potency cannot be guaranteed beyond this period.
With this in mind, I’ve created a table to help you select the right peptide vial based on three key criteria:
- Your weekly dosage
- The strength of the vial
- The optimal cost per month
This way, you can make an informed decision that balances effectiveness, convenience, and value.
| Vial Size | Price (leolab.co.uk) | Best For (Dosage Level) | Estimated Monthly Cost (£) |
|---|---|---|---|
| 3ml | £10 | Ideal for beginners or low weekly peptide dosages; suitable for precise micro-dosing and short cycles | ~£10 (a 3ml vial typically lasts about 1 month at low weekly usage) |
Cost Comparison Per ml
Breaking down the cost helps better understand value:
- £10 ÷ 3ml = ~£3.33 per ml
For comparison, some UK suppliers offer larger 10ml vials at lower per-ml costs (often under £1/ml), but these may differ in quality assurance, testing, or brand positioning.
Value Assessment for Regular Users
While the upfront price of £10 per 3ml vial may seem higher on a per-ml basis, several factors contribute to its overall value:
- High-quality manufacturing and sterility standards
- Bacteriostatic properties allowing multi-use (up to ~28 days after opening)
