Polaris Peptides bac water is bacteriostatic water for lab research. Learn how to reconstitute peptides, store BAC water, and check Polaris Peptides cost.
Polaris Peptides bac water is bacteriostatic water sold by Polaris Peptides for laboratory research. It is sterile water that contains 0.9% benzyl alcohol, a preservative that slows bacterial growth after a vial is opened. Researchers use it to reconstitute lyophilized peptides so that one vial can be accessed multiple times.
What Is Bacteriostatic Water?
Bacteriostatic water for injection, often called BAC water, is sterile water with a bacteriostatic agent added. The most common agent is 0.9% benzyl alcohol. The preservative does not sterilize the solution, but it inhibits the growth of bacteria introduced during repeated withdrawals.
BAC water is not the same as sterile water or normal saline. Sterile water contains no preservative and is intended for single use. Normal saline contains 0.9% sodium chloride and no preservative. Bacteriostatic water contains benzyl alcohol, which is why it is not recommended for newborns and certain patient groups.
In the United States, bacteriostatic water for injection is a prescription product when labeled for human use. Research chemical suppliers often sell BAC water labeled 'not for human use' or 'for laboratory research only.' Polaris Peptides bac water falls into the research-use-only category.
How BAC Water Is Used to Reconstitute Peptides
Lyophilized peptides arrive as a powder that must be dissolved before use. BAC water is a common choice because the preservative allows multiple withdrawals from the same vial over several weeks.
Typical reconstitution steps for laboratory research include:
- Clean the vial stoppers with an alcohol swab.
- Draw the desired volume of BAC water with a sterile syringe.
- Inject the water slowly down the inside wall of the peptide vial.
- Swirl gently; do not shake, because shaking can damage peptide structure.
- Label the vial with the date and final concentration.
The concentration depends on the peptide and the research protocol. A common example is adding 1 mL of BAC water to a 5 mg peptide vial, which yields 5 mg/mL. Another example is adding 2 mL to a 5 mg vial, which yields 2.5 mg/mL.
Some researchers prefer sterile water for single-use applications where no preservative is desired. Others choose BAC water because it reduces the need to open a new vial for every experiment.
Polaris Peptides BAC Water Options
Common formats sold by research suppliers, including Polaris Peptides, are shown below. Always confirm the exact volume and preservative concentration on the product label.
| Format | Volume | Preservative | Typical Research Use | Notes |
|---|---|---|---|---|
| Small vial | 10 mL | 0.9% benzyl alcohol | Reconstituting 1–3 peptide vials | Good for short projects |
| Standard vial | 30 mL | 0.9% benzyl alcohol | Reconstituting multiple peptide vials | Most popular size |
| Multi-dose vial | 30 mL | 0.9% benzyl alcohol | Long-term lab use with repeated withdrawals | Check expiration date |
Polaris Peptides may also sell other research chemicals, such as polaris peptides tirzepatide. These are not the same as BAC water, and they are not FDA-approved for human use.
Ordering, Cost, and Shipping
When you buy from Polaris Peptides, bac water is usually sold alongside peptides and lab supplies. The polaris peptides cost for bac water is generally low compared with peptide vials, but shipping and handling can affect the total. Many buyers read polaris peptides reviews before ordering to confirm packaging quality and delivery times.
The polaris peptides location and shipping policy affect how quickly your order arrives. Domestic shipping within the United States is typically faster than international shipping. A polaris peptides coupon code may be available for first-time buyers or bulk orders, so it is worth checking the website before checkout.
Payment methods vary by vendor. Some suppliers accept credit cards, while others use bank transfers or cryptocurrency. Always confirm the return policy and the research-use-only label before purchase.
Storage and Handling Best Practices
Bacteriostatic water should be stored at room temperature, away from direct sunlight. Do not freeze BAC water, because freezing can break the vial or degrade the preservative. Once opened, the vial should be used within the timeframe stated on the label, often 28 days for multi-dose vials.
Reconstituted peptides usually require refrigeration. Some peptides are stable for weeks at 2–8°C, while others need to be frozen for long-term storage. Follow the specific peptide's documentation.
Use a new sterile syringe and needle for each withdrawal. Never reuse needles. Swab the stopper with alcohol before each entry.
Safety, Legal Status, and Research Use
Polaris Peptides bac water is sold for laboratory research use only. It is not FDA-approved for human injection, and it should not be used for any human or veterinary application.
Benzyl alcohol can cause serious reactions in newborns and infants. Even in research settings, handle BAC water with appropriate personal protective equipment.
If you have questions about a medical condition or treatment, consult a licensed healthcare professional. Do not use research chemicals to self-treat any disease.
Some peptides sold by vendors such as Polaris Peptides are also research chemicals. Their sale does not imply safety or effectiveness for human use.
