Lab Supplies Australia: Shop Bacteriostatic Water, Acetic Acid 0.6% and More Online
NovaPep stocks the lab supplies Australian researchers need to prepare peptides, led by bacteriostatic water in 3 mL, 10 mL and 30 mL vials that you can order with or without a single syringe. You will also find U-100 insulin syringes in three barrel sizes, available individually or in a 30 pack, and a 0.6% acetic acid diluent for sequences that refuse to dissolve in water. Supplies travel from within Australia in the same box as your peptide order.

Buy Bacteriostatic Water Online for Peptide Reconstitution
For lyophilised research peptides, bacteriostatic water is the standard diluent. It consists of sterile water with 0.9% benzyl alcohol added, and that preservative stops bacteria multiplying, which means a single vial can take repeated needle punctures. Plain sterile water has no preservative and is meant for one use, a distinction covered in our guide comparing bacteriostatic and sterile water. Since it copes with many draws from the same bottle, most labs regard it as the best bac water for peptides.
There are three bottle sizes to choose from. The 3 mL vial is enough for one or two peptide vials. The 10 mL vial fits a lab that reconstitutes several peptides each month. The 30 mL vial suits weekly preparation and works out far cheaper per mL than the smallest bottle. Each size can also be ordered with one U-100 syringe included. Pick a size you will actually use up, since a vial is usually thrown out 28 days after it is first punctured. Buy bacteriostatic water online in Australia and it ships from local stock in the same parcel as your peptides.
Order 0.6% Acetic Acid for Hard to Dissolve Peptides
Reach for acetic acid only if a peptide remains cloudy or forms clumps at neutral pH. Acetic acid 0.6% is a mild acidic solution at about pH 3 that dissolves most of these awkward sequences, and many methods then dilute that acid stock further with bacteriostatic water. The textbook case is IGF-1 LR3. Think of it as a backup, not your first choice. Begin with bac water and change over only if the powder will not clear or your protocol calls for an acid diluent. It comes in a single 3 mL vial. Order 0.6% acetic acid online in Australia alongside IGF-1 LR3 or any other sequence known to resist water.
Shop Insulin Syringes Online for Accurate Transfers
Our U-100 insulin syringes are used at the bench to move diluent and draw up measured volumes. The scale is marked in units, with 100 units equal to 1 mL and 10 units equal to 0.1 mL. For adding diluent to a vial, most labs use the 1 mL syringe fitted with a 29G 12.7 mm needle. The remaining three syringes carry a thinner 31G 6 mm needle on 1, 0.5 and 0.3 mL barrels, and the two smaller barrels have wider gaps between their markings, which makes small volumes easier to read. Because the needle is permanently attached, dead space between hub and needle is minimal, so very little liquid is wasted, an important point when you are working with tiny volumes.
Syringes are sold singly or as a 30 pack, which works out cheaper per syringe. For a closer look at the barrel options, read our guide to insulin syringes. Insulin syringes are for sale in Australia in four barrel and needle options, sent tracked with the rest of your order.
Buy the Right Lab Supplies for Your Monthly Volume
The number of vials you reconstitute each month is the best guide to what to buy. If you are preparing one 10 mg peptide vial, the option of a 3 mL bacteriostatic water vial plus a syringe covers everything. If your lab prepares three or more vials monthly, the 10 mL bottle combined with the 30 pack of syringes is better value. High fill products such as 1,500 mg glutathione or 500 mg NAD+ need more liquid per vial, so a 10 mL or 30 mL bottle is sensible even for one order. Only add acetic acid for sequences that are known to resist water. You can buy NAD+ online from our Australian stock as a 500 mg fill, and its lot certificate sits in our COA library.
Work out your target concentration before any liquid goes in. For example, adding 2 mL to a 10 mg vial gives 5 mg per mL, and our peptide calculator covers every other fill weight. Prefer not to pick parts yourself? Our peptide kits and bundles each combine a peptide with the right water and a syringe. The complete step by step method is set out in our guide to reconstituting peptides.
Order Supplies Knowing How to Store Them
Sealed bacteriostatic water and acetic acid can be kept at room temperature, away from direct sunlight and heat. When you first pierce the stopper of a water vial, mark the date on it so the 28 day limit is easy to track. Each syringe is sterile and meant for a single use, so use a new one for every draw and dispose of it afterwards. After a peptide has been reconstituted, store it in the fridge at 2 to 8 °C, and refer to our guide to storing peptides for everything else.
Shop Bacteriostatic Water Australia Wide, Shipped With Your Peptides
Add supplies to the same order as your peptides so a single delivery sets up the whole bench, and the bacteriostatic water Australia labs rely on turns up alongside the vials it will dissolve. Every peptide in the parcel carries a lot number linked to its identity and purity certificate in our COA library. When payment lands before 3pm on a business day, we ship that day with tracking to all Australian states. These supplies are intended for preparing research peptides in a laboratory setting by adults 18 and over, and are not for giving anything to animals or people.

Lab Supplies FAQ
Where can I get bacteriostatic water for peptides in Australia?
NovaPep sells bacteriostatic water in three sizes, 3 mL, 10 mL and 30 mL, and you can add one U-100 syringe to any of them. Stock is held in Australia, and orders paid by 3pm on a business day are dispatched that day with tracking.
What supplies does a lyophilised peptide need?
You will need a diluent, normally bacteriostatic water, a U-100 insulin syringe to move it into the peptide vial, and alcohol swabs to clean the stoppers. A single 10 mg vial is covered by the 3 mL water vial with a syringe. After that, our peptide calculator tells you the final concentration.
When is acetic acid a better choice than bacteriostatic water?
Use it only if a peptide fails to dissolve cleanly at neutral pH, or if your method calls for an acid diluent. The best known example is IGF-1 LR3. The 0.6% solution sits near pH 3 and normally clears the powder, and many labs then dilute it further with bacteriostatic water. It comes in a single 3 mL vial.
What size insulin syringe is right for my lab?
To add diluent to a vial, most labs pick the 1 mL 29G syringe. To measure small volumes, choose the 0.5 mL or 0.3 mL barrel with a 31G needle, as the wider spacing between markings gives a more precise reading. Syringes are sold singly or in a 30 pack.
How long can bacteriostatic water be used after opening?
Although benzyl alcohol restricts bacterial growth, an opened vial is normally thrown away 28 days after its stopper is first pierced. Sealed vials can stay at room temperature, protected from light and heat. To avoid waste, pick a bottle size your lab will get through inside that period.
