Sterile Water

Description

Sterile Water is a sterile water for reconstitution from Pure Rawz. It’s sold as a laboratory supply for research use.

Sterile Water explained

Sterile water is purified water that has been sterilized and sealed in a vial. It has no preservative, so once the stopper is pierced it’s meant for a single use.

It’s the plain alternative to bacteriostatic water.

Mechanism of action

Water dissolves most freeze-dried peptides, which are mostly water-soluble. Without a preservative, bacteria can grow after the seal is broken, so mixed solutions should be used quickly.

Pick bacteriostatic water instead if you’ll draw from the vial over several weeks.

Published Sterile Water research

Labs use sterile water when a preservative would interfere with an assay, or when the whole vial will be used at once.

Benzyl alcohol, the preservative in bacteriostatic water, can affect some cell cultures.

The primary literature is on PubMed. Here’s a search to start from.

Options and prices

There are 3 ways to buy it, from $3.81 to $8.18:

• 10ml: $3.81
• 20ml: $8.18
• 30ml: $8.18

Study design notes

Reconstitution liquids and solvents are the part of a protocol that’s easy to overlook. The wrong liquid can stop a peptide dissolving, change its stability or interfere with an assay.

Match the liquid to the compound and to how long you’ll keep the solution. Single-use work can use sterile water, while multi-draw vials need a preservative.

Buy in the size you’ll use before the expiry date. A large bottle that sits open for months isn’t a saving.

Sterile Water product details

• Options: 3 sizes and forms
• Use: laboratory research only

Storage and shelf life

Store solvents tightly capped at room temperature, away from heat, flames and direct light. Note the batch number and the date you opened it in your lab records.

Our reconstitution and solvent range

Different compounds need different liquids. Here’s how our range lines up:

• Bacteriostatic Water: the default for most peptides, with 0.9% benzyl alcohol so a vial can be drawn from for several weeks
• Sterile Water (this page): no preservative, for single-use mixing or assays where benzyl alcohol would interfere
• Acetic Acid Reconstitution Solution: dilute acid for peptides that dissolve poorly in water, such as IGF-1 LR3
• Phosphate Buffered Solution: holds the pH near 7.4 for dilutions and cell work
• L-Glutathione Reconstitution Solution: adds an antioxidant for peptides prone to oxidation
• Reconstitution Solution: a general-purpose sterile diluent for the shelf
• DMSO Dimethyl Sulfoxide: a strong solvent for stock solutions of compounds that won’t dissolve in water
• Benzyl Alcohol USP Grade: preservative and co-solvent for oil-based solutions
• Grape Seed Oil 100% Filtered: a light carrier oil for fat-soluble compounds

Safe handling

Wear gloves and eye protection, work in a ventilated area, and keep flammable solvents away from heat and open flames. Close the bottle after each use.

Other compounds to look at

• Propylene Glycol: Propylene glycol is a clear, slightly sweet liquid used as a solvent and humectant.
• Grape Seed Oil 100% Filtered: Grape seed oil is pressed from grape seeds left over from winemaking.
• Reconstitution Solution: Our reconstitution solution is a sterile 10mL vial of liquid for dissolving freeze-dried research peptides.
• Denatured Ethanol 99.5%: This is 99.5% ethanol with a denaturant added so it can’t be drunk.
• Benzyl Benzoate USP Grade: Benzyl benzoate is an ester of benzyl alcohol and benzoic acid.

Alternatives to consider

Reconstitution Solution: Our reconstitution solution is a sterile 10mL vial of liquid for dissolving freeze-dried research peptides.

Phosphate Buffered Solution: Phosphate buffered solution is salt water with sodium and potassium phosphate added to hold the pH near 7.4, close to body fluid.

Common questions about Sterile Water

What forms does it come in?

It comes in 3 sizes, listed in the dropdown on this page.

Is Sterile Water in stock?

Yes. It’s in stock and ships from our warehouse after your order clears.

Does it come with a certificate of analysis?

Yes. Every batch is tested, and we’ll email the certificate of analysis for your batch number on request.

Can it be used in people or animals?

No. It’s sold for laboratory research only and isn’t approved for human or veterinary use.

How should I store it?

Follow the storage section above. In short: cold and dark for freeze-dried vials, room temperature and dry for capsules, tablets, powders and liquids, unless the label says otherwise.
