Buy Acetic Acid for Peptides in Australia
Buy acetic acid in Australia from Macropus Peptides as a dilute acetic acid diluent for peptides, supplied in a sealed 3mL glass vial. Some research peptides, most notably IGF-1 LR3, dissolve poorly or aggregate in neutral diluents, and a dilute acetic acid in water gives them the mildly acidic conditions they need to go into solution cleanly. Each vial is labelled with product, volume, concentration, lot number and storage conditions, and we supply the batch certificate for any lot on request. The 3mL vial is sized for reconstituting small peptide vials without leftover waste, at a fixed low price. It is a dilute laboratory solution, not glacial acetic acid, and a safety data sheet is available on request. Order acetic acid online with your peptides so everything arrives in one parcel, dispatched from Australia to any Australian address. Acetic acid for sale to researchers aged 18 and over for in-vitro laboratory research only; not for human or veterinary use.

Buy Acetic Acid Australia: 3mL Diluent Vial for Peptides
Macropus Peptides supplies acetic acid as a ready-to-use dilute solution in a sealed 3mL vial, made for reconstituting research peptides that need an acidic diluent. It is the partner product for peptides such as IGF-1 LR3, and it sits in our lab supplies range alongside bacteriostatic water, so a laboratory can order its peptide and the right diluent together.
Acetic acid for peptides: what is acetic acid
Acetic acid is the simple carboxylic acid that gives vinegar its sharp smell, written chemically as CH3COOH. In its pure, undiluted form it is known as glacial acetic acid, because it freezes into ice-like crystals at around 16 °C; glacial acetic acid is a concentrated, corrosive reagent. The product we supply is not glacial acetic acid. It is a dilute acetic acid in water, prepared at a low concentration suited to peptide work, with the exact strength stated on the label and the certificate of analysis. Acetic acid is a weak acid with a pKa of about 4.76, which means it lowers pH gently rather than sharply, one reason it is so widely used with biological molecules.
Acetic acid in water: how acetic acid works for peptide research
Every peptide has its own charge profile, and some carry a surface that makes them clump together or resist dissolving at neutral pH. A weak acid solution lowers the pH, adds positive charge to basic amino acid side chains and keeps the peptide molecules apart, so they dissolve fully instead of forming aggregates. That is why datasheets for IGF-1 LR3 and several other growth factor analogues specify a dilute acid rather than water. Acetic acid is also volatile, so it can be removed by freeze-drying, and it is a standard component of the mobile phases used to analyse peptides by HPLC, which makes it familiar to almost every peptide laboratory.
Acetic acid for peptides: what the research shows
The case for acidic diluents comes from decades of peptide formulation science. Reviews of peptide and protein stability in Pharmaceutical Research in 2010 and the International Journal of Pharmaceutics in 1999 set out how pH controls solubility, aggregation and chemical degradation in solution, and why many peptides are most stable below neutral pH. Work on long-acting IGF-I analogues reported by the Journal of Molecular Endocrinology back in 1992 underpins the analogue now sold as IGF-1 LR3, the peptide most often paired with acetic acid today. The studies behind this product are listed in our acetic acid research studies library.
Acetic acid vial specifications
| Specification | Detail |
|---|---|
| Compound | Acetic Acid |
| Amount | 3 ml |
| Form | Laboratory supply |
| Category | Lab supplies |
| Storage | See label |
Each vial holds 3mL of the dilute solution under a sealed closure. The label gives product name, volume, concentration, lot number and storage conditions, and the lot number traces the vial to its certificate of analysis. Store the sealed vial at room temperature away from direct light; once the septum has been pierced, keep it refrigerated and use a fresh sterile needle for every draw.
Acetic acid price in Australia
| Option | Price |
|---|---|
| Acetic Acid 3mL | $12.99 |
The 3mL vial carries one fixed low price in Australian dollars. Because a single vial reconstitutes several small peptide vials, most laboratories add one or two to each peptide order rather than buying diluent separately.
Acetic acid 3mL: where to buy in Australia
The 3mL size is matched to how acidic diluents are actually used: a small volume per peptide vial, typically 1 mL or less for a 1mg IGF-1 LR3 vial. A larger bottle would sit open for longer and risk contamination, while 3mL is used up across a few reconstitutions. It is available to order now and ships with your peptides.
Best place to buy acetic acid Australia
- Dilute acetic acid prepared for peptide reconstitution, not glacial reagent
- Concentration stated on the label and on the certificate of analysis
- Sealed 3mL vial sized for small peptide vials
- Lot number printed on every label for full traceability
- Dispatched from within Australia in the same parcel as your peptides
Acetic acid purchase: how to get it online
- Add the 3mL vial to your cart
- Add the peptide it will be used with, such as IGF-1 LR3
- Add bacteriostatic water if other peptides in the order need it
- Pay and confirm the purchase is adult laboratory use
- Keep the lot number on file and request the certificate if required
Acetic acid buffer and peptide calculator
Plain dilute acetic acid suits most reconstitutions. Where a protocol needs a fixed pH, laboratories combine acetic acid with sodium acetate to make an acetic acid sodium acetate buffer, which holds pH steady in the range around 4 to 5.5. For volumes, the concentration calculator on every peptide listing works with any diluent: a 1mg IGF-1 LR3 vial reconstituted with 1 mL of acetic acid gives 1 mg per mL, or 1,000 mcg per mL. Pair this vial with IGF-1 LR3, and use bacteriostatic water for peptides that dissolve at neutral pH.
Acetic acid SDS and safety data sheet in Australia
Dilute acetic acid is far less hazardous than the glacial form, but it is still a laboratory chemical and should be handled with gloves and eye protection, away from bases and oxidising agents. A safety data sheet for acetic acid covering the dilute solution is available on request with your order, alongside the certificate of analysis for the lot. Like every product we sell, it is supplied only for in-vitro laboratory research and never for use in people or animals.
Acetic acid for sale Australia wide: sent with your peptides
We pack each vial beside the peptides it goes with and post the parcel from local Australian stock to any state or territory. The full range of diluents, kits and consumables is in lab supplies and kits, and the peptides that use it are in our growth hormone research range.
