Peptide Syringes

Peptide syringes are designed for administering small volumes of liquid with precision and control. For injectable peptides that are intended for subcutaneous administration, insulin syringes are a commonly used option. Their fine needles, compact design and clearly marked measurement scales make them suitable for handling small injection volumes. We offer a selection of high-quality insulin syringes with different needle lengths, gauges and capacities, including popular 6 mm and 8 mm options.

What are peptide syringes?

Peptide syringes are not a separate category of medical syringes. The term generally refers to syringes used for administering injectable peptide solutions. Depending on the product and its intended application, peptides may be administered through different routes. For peptides intended for subcutaneous injection, insulin syringes are frequently used. These syringes combine a small barrel with a fine, permanently attached needle, allowing users to measure and administer small volumes of liquid. Not all peptides are intended for injection, and the appropriate syringe and administration method depend on the specific product and its instructions.

Popular leedle lengths: 6 mm and 8 mm

When choosing a syringe for subcutaneous injections, needle length is an important consideration. Two popular options are 6 mm and 8 mm insulin syringes. The 6 mm insulin syringes feature a relatively short needle and are often selected for subcutaneous injections. The compact needle length makes them a popular choice for applications requiring a fine, short needle. The 8 mm needle is another widely available option. It offers a slightly longer needle while maintaining the fine diameter typically associated with insulin syringes. Other needle lengths, including 12.7 mm, are also available. The appropriate length depends on the intended application and the manufacturer’s instructions.

Needle gauge: 30G, 31G and 32G

Besides needle length, needle thickness is another important specification. Needle thickness is expressed in gauge (G). The higher the gauge number, the thinner the needle. Common options include:

• 30G (0.30 mm): A fine needle commonly found on insulin syringes
• 31G (0.25 mm): A thinner needle, frequently available in 6 mm and 8 mm lengths
• 32G (0.23 mm): An even finer needle, available on certain insulin syringe models

The choice of needle gauge depends on the intended application, the properties of the liquid and the manufacturer’s recommendations.

Syringe capacity and measurement

Insulin syringes are available in different capacities, typically 0.3 ml, 0.5 ml and 1 ml. Smaller syringes offer measurement scales suited to small liquid volumes. Many insulin syringes feature U-100 markings, originally designed for U-100 insulin. These markings represent insulin units rather than a universal peptide dosage. For example, on a U-100 syringe, 100 units correspond to 1 ml of liquid. It is important to distinguish between volume measurements and the amount of peptide contained in a solution.

Single-use

Insulin syringes are sterile medical devices intended for single use only. Each syringe should be used once and disposed of safely after use. Reusing a syringe can compromise sterility and damage the fine needle tip. Used needles and syringes should always be discarded in an appropriate sharps container, following local disposal guidelines.
