## About

This is the only Supply-grade line in the Australian Research Peptides catalogue, and it is measured differently from everything around it. The figure on the listing counts syringes in a sealed pack. Peptides are listed by mass and bacteriostatic water by volume, so neither of those units would describe this item honestly.

Nothing in the COA library covers this pack. A COA is a certificate of analysis, the document that reports what a laboratory test found in a batch. There is no equivalent test for a physical article, and ARP does not publish a result it has never produced.

The barrel is the part worth reading before ordering. It holds half a millilitre and carries a unit scale running to fifty, with a printed line at every fifth unit. On the U-100 scale a hundred units fill one millilitre, so a single unit is a hundredth of a millilitre and a full barrel is half of one. That relationship lets any reading on the barrel be converted directly to millilitres.

Australian Research Peptides lists these syringes in Australia in sealed packs of twenty, stocked as a laboratory consumable in Lab Supplies alongside bacteriostatic water. They are also searched as U-100 syringes and unit syringes. Packs are held locally and posted to every state and territory. As a physical article rather than a compound, the pack carries no certificate of analysis and none is published for it.

## Questions

### Where can I buy Graduated Syringes in Australia?

Graduated Syringes are supplied by Australian Research Peptides from within Australia, sealed by the pack and filed under Lab Supplies. Each barrel holds 0.5 mL and is graduated to 50 I.U. with a printed line every 5 units, and a 31G 6 mm capped needle fitted. Orders lodged on a business day before 12pm Sydney time leave the same day, and both express and standard tracked postage serve every Australian state and territory. The pack posts from inside the country, so there is no customs step and no international transit wait.

### What are Graduated Syringes used for in the lab?

Graduated Syringes draw a measured volume of liquid out of a sealed vial. In peptide work that liquid is usually reconstituted material, made up with bacteriostatic water. The scale printed on the barrel is what makes the volume measurable. Australian Research Peptides supplies the pack as a laboratory consumable, for in vitro research purposes only.

### What is in the Graduated Syringes pack?

The pack holds single-use graduated syringes, sealed, at the quantity Australian Research Peptides catalogues it in. Each one carries a fitted 31G 6 mm capped needle and a 0.5 mL barrel graduated to 50 I.U. with a printed line every 5 units. Those figures come from the supplier's own listing for the article ARP stocks, not from a photograph of it.

### How much do Graduated Syringes cost in Australia?

Australian Research Peptides prices Graduated Syringes by the sealed pack, not by the individual syringe. A single pack size is listed, so there is one figure rather than a ladder across sizes, and no per-syringe figure is printed beside it. A second pack is charged at the same figure as the first, however many packs are ordered.

### Are these Graduated Syringes single-use?

These Graduated Syringes are single-use. Australian Research Peptides catalogues them in one sealed pack of twenty. Each syringe has a capped needle and a barrel marked in units. The buy panel on this page shows whether the pack can be ordered at that moment, so the availability statement does not go stale inside an FAQ.

### What do the numbers on a Graduated Syringe barrel mean?

Each barrel is marked I.U. and numbered to 50, which is what a 0.5 mL barrel holds on the U-100 scale. A printed line falls on every multiple of five, so 5, 10, 15 and so on each sit on a line and anything between them is judged against its two neighbours. These syringes carry a unit scale instead of a millilitre scale, and one unit is 0.01 mL.

### What gauge and needle length do Graduated Syringes have?

The needle fitted to this pack is 31 gauge and 6 mm long, and it is capped. Gauge is a measure of the needle's outside diameter, and a higher gauge number means a narrower needle. The barrel it is fitted to holds 0.5 mL and is graduated to 50 I.U. with a printed line every 5. Australian Research Peptides supplies the pack as a laboratory consumable.

### Are Graduated Syringes sterile?

The pack arrives sealed from the manufacturer and the syringes inside it are single-use. Australian Research Peptides supplies it as a laboratory consumable and describes it by what the pack itself states. Contact ARP before ordering if a specific detail settles the purchase.

### Do Graduated Syringes come with bacteriostatic water?

No, Graduated Syringes and bacteriostatic water are separate products, each bought individually and both catalogued by Australian Research Peptides under Lab Supplies. Neither is included inside a peptide vial: the water is the diluent, and the syringes are how material is drawn back out.

### Why is the Graduated Syringes pack counted by the syringe and not in millilitres?

The number on an Australian Research Peptides Graduated Syringes pack counts syringes, because a count is what is being sold. Milligrams describe a peptide and millilitres describe a liquid, and neither describes a box of articles. The unit marks printed on each barrel are a different thing entirely. Every ARP product carries its own unit field.

### What size syringe is used for laboratory peptide work?

A U-100 graduated syringe is the usual choice for laboratory peptide work, because the volumes handled are small and a unit scale measures them more finely than a larger syringe can. U-100 describes the scale rather than the barrel: 100 units fill 1 mL, so one unit is 0.01 mL whatever size the barrel is. Australian Research Peptides supplies the 0.5 mL size, which holds 50 units.

### Do the Graduated Syringes come with the needle attached?

Australian Research Peptides’ Graduated Syringes are supplied with a fixed needle rather than as a separate barrel and tip, which is the standard format for a syringe of this size and removes the dead space where fluid is otherwise lost. The gauge and length are stated in ARP's published specifications.

### Can one syringe be used both to add diluent and to withdraw solution?

Using one graduated syringe both to add diluent and to withdraw solution carries contamination from the first vial entry into the second, so a separate syringe for each step is conventional laboratory practice. That is one reason the Australian Research Peptides pack holds twenty.

### How should used syringes be disposed of in Australia?

Used syringes go into a rigid, puncture-resistant sharps container meeting [AS 4031 or AS/NZS 4261](https://www.health.vic.gov.au/infectious-diseases/cleaning-and-waste-disposal-procedures-infection-control), never into general waste or recycling. A laboratory disposes of filled containers through its clinical-waste contractor under the waste-management rules of its own state or territory. Containers are sealed at the fill line and never decanted.

### What else is used with Graduated Syringes in the laboratory?

Graduated syringes are one of three items used in laboratory peptide handling: a sealed vial of freeze-dried material, a diluent to reconstitute it, and syringes to transfer and draw the solution. Australian Research Peptides lists each one separately, and the syringe pack is sold on its own as a laboratory consumable.

### How should Graduated Syringes be stored?

Graduated Syringes are stored dry, sealed and at ordinary room temperature. Australian Research Peptides publishes no cold-storage condition for this pack, so no fridge or freezer is involved. Keep it away from heat, damp and direct sunlight, and leave the seal intact until the pack is opened. Peptide vials in this catalogue have a quite different storage line.

### Do I need bacteriostatic water as well as syringes?

Yes, Graduated Syringes transfer liquid but do not supply it: freeze-dried peptide material is reconstituted with a diluent such as bacteriostatic water before a syringe has anything to draw. Australian Research Peptides lists bacteriostatic water separately, in 3 mL and 10 mL vials.

### How many units are in 1 mL on a U-100 syringe?

A U-100 barrel is graduated so that 100 marks span one millilitre, which is what the U-100 label on the scale means. One mark is therefore 0.01 mL, ten marks is 0.1 mL, and fifty marks is half a millilitre. The barrel Australian Research Peptides supplies holds 0.5 mL, so it runs to 50 with a printed line every 5.

### Who supplies Graduated Syringes in Australia?

Graduated Syringes are supplied by Australian Research Peptides Pty Ltd (ARP), from an Australian dispatch address under stock code 51521. A weekday order completed before 12pm Sydney time is dispatched the same working day, and Express Post is available across all states and territories, alongside tracked standard post. Nothing travels internationally to reach you. Payment runs through PayID or direct bank transfer, each carrying the order reference issued at checkout.

### Do Graduated Syringes qualify for free shipping in Australia?

A syringe pack counts toward the free-post thresholds like anything else in the basket, but it is far too inexpensive to reach either on its own. Free post is read on the goods subtotal before any discount code, so a code never changes whether a basket qualifies.

### How do you order Graduated Syringes online in Australia?

Graduated Syringes are sold across Australia by Australian Research Peptides, which supplies them sealed by the pack as a laboratory consumable beside its research peptides. Payment is by PayID or direct bank transfer, paid from the buyer's own banking rather than through a form on this site. Every pack goes out from within Australia, so nothing waits at a border.

### How long do Graduated Syringes take to arrive in Australia?

Graduated Syringes ordered before 12pm Sydney time on a business day are dispatched the same afternoon, posted from within Australia so nothing waits at customs. Standard tracked post typically takes 2–5 business days. Express Post is quicker: one to two days into ACT, NSW, Victoria and South Australia, up to three into Queensland, up to four into Western Australia and the NT. The pack ships sealed in its manufacturer's packaging inside the same parcel as the rest of the order, so no separate delivery arrives.

### How do I pay for Graduated Syringes?

Graduated Syringes are paid for by PayID or bank transfer like everything else, and there is no minimum order value — a pack of syringes on its own is a valid order. Postage still applies to a small order.

### Are Graduated Syringes FDA approved?

Graduated syringes are not FDA approved, because syringes are devices rather than drugs and devices follow a different American route: most reach that market through [510(k) clearance](https://www.fda.gov/medical-devices/premarket-submissions-selecting-and-preparing-correct-submission/premarket-notification-510k), which demonstrates equivalence to something already sold rather than approving a new medicine. Rules also differ by country, so Australian supply answers to the [Therapeutic Goods Administration](https://www.tga.gov.au/products/medical-devices)'s device framework instead.

### Can you buy Graduated Syringes legally in Australia?

Graduated syringes are widely available in Australia as a laboratory consumable. Australian Research Peptides supplies them to laboratories and researchers for measuring and transferring small volumes alongside its research peptides, so a peptide order does not have to be split across two suppliers.

### Are Graduated Syringes tested before they are supplied?

No, Australian Research Peptides runs no analytical test on the syringe pack before supply. A syringe is a manufactured article rather than a compound. HPLC and mass spectrometry work by separating and weighing a compound, and a syringe offers nothing to separate or weigh. The specification block describes the article itself, never a laboratory result.

### Is there a Certificate of Analysis for the Graduated Syringes?

The Graduated Syringes do not use a peptide Certificate of Analysis because there is no compound in the pack to test. The pack is identified by its supplier packaging rather than a laboratory document.

### What else are Graduated Syringes known as?

Graduated Syringes are often called U-100 syringes or unit syringes, after the unit scale printed on the barrel. Australian Research Peptides catalogues them under one name, in a sealed pack of twenty, as a laboratory consumable for measuring and transferring liquid.

### Are Graduated Syringes sold by other suppliers in Australia?

Yes, graduated syringes of this type are widely sold in Australia, so availability is not the reason to order them from Australian Research Peptides. ARP lists a 20-pack so laboratories and researchers receive it in the same parcel as their research peptides and bacteriostatic water, saving a separate order and a second delivery.
