The pack label names the contents as U-100 syringes for 100 units or less, and its size panel lists needle lengths of 1/2 inch (12.7 mm) and 5/16 inch (8 mm). Veracue offers the pack as a laboratory supply for bench work with small liquid volumes, strictly for research use only, and it gives no usage guidance of any kind. ## Product Details ### What Is in the 10 Needles Pack? 10 Needles is a sealed retail pack of ten syringes, each fitted with a short needle. The front of the pack states the count as 10 needles and the gauge as 31, and a size panel beside it lists two needle lengths, 1/2 inch (12.7 mm) and 5/16 inch (8 mm). A further line describes the contents as U-100 syringes for 100 units or less, which refers to the unit scale printed on the barrel. Veracue lists the pack as a laboratory supply, separate from the research compounds in its catalog. In the product photograph the pack sits in a clear sealed bag with a navy blue and yellow printed panel. Two loose syringes are laid below it, one with its needle exposed and one with an orange needle cap. They illustrate the syringe type, and the printed pack, not the photograph, defines the contents. ### 10 Needles at a Glance Product name: 10 Needles Product type: Laboratory supply: syringes with attached needles; not a peptide and not a research compound Pack count as labeled: 10 needles Needle gauge as labeled: 31 gauge Needle type as labeled: Short needle Needle lengths named on the pack: 1/2 inch (12.7 mm) and 5/16 inch (8 mm) Barrel scale as labeled: U-100, for 100 units or less Pack label wording: U-100 insulin syringes, short needle Packaging as photographed: Sealed clear bag with a printed panel Research designation: Research Use Only Everything in this table is read from the printed pack shown in the product photograph. The pack you receive carries its own label, and that label, not this listing, is the record for the pack in hand. Questions can go through the contact page. ### What 10 Needles Is Not - Not a sterility claim. The listing states no sterilization method and no sterile status. - Not a single stated length. The size panel names two lengths, so confirm which one your pack holds before ordering if length matters to your work. - Not a kit. The listing describes syringes only. - Not a peptide or an active compound. - Not intended for human or veterinary use. ## Research Focus & Mechanism Overview ### Reading the Gauge Number ### What does 31 gauge mean? Gauge is a size scale for needle bore, and the number runs opposite to the width: a higher number is a thinner needle. A 31 gauge needle is about 0.25 mm in outer diameter, far finer than the roughly 0.8 mm of a 21 gauge needle common on general-purpose laboratory syringes. Gauge says nothing about length, which is stated separately. ### Why are gauge and length listed apart? They are independent properties. A 31 gauge needle can be short or long, so a researcher choosing a supply should record both. On this pack the gauge is printed once in large type, while two lengths are named in the size panel next to it. ### Attached Needles and Barrel Scales As photographed, the needle on each syringe is attached directly to the barrel. An attached needle removes the question of matching a separate hub or connector, because there is no hub to match. It also means the needle cannot be swapped for another gauge or length, so the size printed on the pack is the size supplied. The barrel carries a printed scale in units, and the pack calls it U-100. That marking is a calibration convention for the scale. It is not a procedure, a volume recommendation or a statement about any material, and Veracue gives no ratios, volumes or procedures for this item. ### Choosing a Supply for Bench Work The table lists the properties a researcher usually records for a needle supply and where each one is stated for 10 Needles. Property: Why a researcher records it: Where it is stated here Count: Planning and budgeting depend on the number in the pack: Pack label: 10 needles Gauge: Sets the bore, which affects fit through narrow openings: Pack label: 31 gauge Length: Sets the reach, which matters for container depth: Size panel names 1/2 inch and 5/16 inch; confirm with Veracue Needle attachment: Decides whether a separate hub must be matched: Attached to the barrel as photographed Barrel scale: Decides which markings are available for reading a volume: Pack label: U-100, for 100 units or less Sterility and material: Matters for sterility-sensitive work: Not stated; see Quality & Purity Standards ### Sharps in the Laboratory Used needles are sharps. Handling and disposal follow the researcher’s own institutional protocol and local rules, not a supplier’s product listing, and Veracue publishes no disposal procedure for this item. ## Quality & Purity Standards ### What This Listing States and Does Not State This listing states the product name, the count, the gauge, the unit scale and the needle lengths named on the printed pack in the photograph. It does not state a sterilization method or sterile status, a needle or barrel material, a manufacturer, a country of origin, a lot number, an expiration date, a storage condition or a test result, and it presents no certificate of analysis for this item. Veracue’s certificate library is organized around peptide lots and holds no record for this supply. Questions can go through the contact page, and the certificate page shows what documentation exists. ### Pack Checks on Arrival These checks involve no test results, only a comparison of the pack against the order and the record. Check: What to look for: What it tells you Count: 10 needles stated on an unopened pack: The pack matches the listing Gauge: 31 gauge printed on the pack: The bore matches the order Length: Whichever of 1/2 inch or 5/16 inch your pack indicates; ask Veracue if it is unclear: Which of the two named lengths was supplied Seal: An intact sealed bag with no tears or punctures: Visible signs that a pack should be set aside and reported Lot and date: Any lot number or date printed on the pack: The link to batch records, if the supplier holds any Barrel markings: A legible printed unit scale on the syringes: The scale described on the label is present ### Common Questions About Verification ### Does a sealed pack show the contents are sterile? No. A sealed bag shows that the pack has not been opened, while sterility is a separate property that needs its own statement and documentation. This listing makes no sterility claim. ### What belongs in a procurement record? Keep a snapshot of the listing, the count, gauge and length read from the pack, any lot number or date printed on it, the date received and the work it supported. Consistent records make pack-to-pack differences visible. ### Questions about this item?

A sealed pack of ten syringes with short 31 gauge needles attached, as printed on the pack in the product photograph. It is listed as a laboratory supply, not a compound. ### How many needles come in one pack? The pack label states 10 needles. The two loose syringes in the photograph illustrate the syringe type and are not an extra count. ### What gauge are the needles? The label prints 31 gauge. On the gauge scale a higher number means a thinner needle, and 31 gauge is about 0.25 mm in outer diameter. ### What needle length does the pack contain? The size panel on the pack names two lengths, 1/2 inch (12.7 mm) and 5/16 inch (8 mm), without marking which one a given pack holds. If length matters to your work, confirm it with Veracue before ordering. ### What does U-100 on the label mean? It names the unit scale printed on the syringe barrel, a calibration convention of 100 units per milliliter. It describes the markings only and is not a procedure or a recommendation. ### Is the needle attached, or does it need a separate connector? As photographed, the needle is attached directly to the barrel, so there is no separate hub or connector to match. That also means the gauge and length cannot be changed. ### Are the needles sterile? This listing makes no sterility claim and states no sterilization method. A sealed bag shows only that the pack is unopened, so ask Veracue for documentation before using the item in sterility-sensitive work. ### Are the syringes individually wrapped? The photograph shows the ten-count pack in one sealed clear bag. Individual wrapping inside it is not stated, so the listing makes no claim either way. ### Does the photograph show exactly what I will receive? It shows the printed retail pack plus two loose syringes laid beside it for illustration. The label on the pack you receive is the record for that pack. ### Does the pack include vials, diluent or other items? No. The listing describes the ten syringes only and is not a kit. ### How should used needles be disposed of? Follow your institution’s sharps protocol and the local rules that apply to you. Veracue publishes no disposal procedure for this item. ### Is there a certificate or datasheet for 10 Needles? Not at present. The certificate library is organized around peptide lots, so no record exists there for this supply. Ask through the contact page if you need to know what documentation can be provided. ### The pack mentions insulin syringes. Does that change how this item is listed? No. The words are the device description printed on the pack. Veracue lists the item as a laboratory supply for research use only, not for human or veterinary use. ### What does Research Use Only mean for this item? It means the supply is sold only for laboratory research, not for human or veterinary use or any form of administration. It is a supplier designation and does not override applicable law. ### Does Veracue provide usage instructions for 10 Needles? No. 10 Needles is offered for laboratory research use only, and Veracue provides no dosing, administration or usage guidance of any kind. More from Veracue Labs: https://veracuelabs.com/llms.txt
