GLUCO-CARE 0.3 ml/cc Syringes — 100 Count

These 0.3 ml syringes are sized for small-volume dosing with a 31G, 5/16″ (8 mm) needle. They come in a box of 100 and feature a smooth plunger designed for one-hand operation. The graduations are bold and easy to read, helping ensure accurate dosing every time. Best for high-volume users or laboratories that require bulk supplies.
Who it’s for: Medical aides, clinics, or home users who need a large quantity of consistent 0.3 ml syringes. Best for reliable repetition with minimal reordering concerns.
Why selected: The large batch reduces restocking frequency. Clear graduations support precise measurement, and the smooth plunger design minimizes hand fatigue during repetitive dosing.
Limitation: With a 100-count box, storage space matters for small workspaces; consider storage containers if space is tight.
GLUCO-CARE 0.3 ml/cc Syringes — 50 Count

This 50-piece variant shares the same essential features: 0.3 ml capacity, 31G x 5/16″ (8 mm) needle, and a clear measurement scale. The practical packaging makes it a good choice for smaller clinics or individual professionals who don’t need bulk quantities. It mirrors the 100-count option in performance and ease of use.
Who it’s for: Individual practitioners, small clinics, or home users who want a mid-sized pack without sacrificing measurement clarity.
Why selected: It provides a balance between affordability and reliability when a full case is unnecessary.
Limitation: Fewer units may require more frequent reordering if dosing tasks are high-volume.
U-100 1/2 ml Syringe with Needle

This option provides a larger capacity at 1/2 ml with a 31G needle. It comes in a sterile, individually packaged form, and the design emphasizes a smooth plunger and a leak-proof seal. The five-faceted needle production and electro-polishing are noted as part of the manufacturing quality. Best for beginners who need a simple, all-in-one solution that can handle a variety of small-dosed tasks.
Who it’s for: New users or facilities seeking a versatile syringe that can cover multiple small-dose scenarios with a single tool.
Why selected: Ease of use and a straightforward design can reduce the learning curve for first-time syringe users.
Caution: This option has a higher volume capacity, which may lead to slightly larger doses if the user is specifically targeting 0.3 ml measurements; ensure proper calibration to avoid over-dosing.
Atsuhut 0.3 ml Lab Syringe — 100 Pack

This 0.3 ml syringe is designed for precise measurement with a 31G needle and a 1/4″ (6 mm) length. It is individually wrapped for sterility and portability, making it suitable for fieldwork or shared workspaces. The labeling emphasizes an easy-to-read extended graduation scale, improving dose accuracy during routine tasks.
Who it’s for: Professionals who require compact, portable syringes with strong dose-readability on the go.
Why selected: The individually wrapped packaging reduces cross-contamination risk in shared settings.
Caution: The shorter needle length may not be suitable for all injection angles or solution viscosity; verify compatibility with your intended use.
Ezoon 0.3 ml Syringe — 100 Pack

Ezoon’s 0.3 ml option is designed for precise measurement and reliable operation. It uses 30G × 13 mm needles and comes in a 100-pack, with individual packaging to preserve sterility and ease of transport. The product highlights durability and a smooth plunger for one-handed operation, making it a practical pick for repeated small-dose tasks.
Who it’s for: Lab technicians and clinicians who need a dependable, long-lasting supply of compact syringes with a longer needle option for certain solutions.
Why selected: The longer needle length can be advantageous for viscosity or specific injection approaches, while maintaining 0.3 ml capacity for accurate dosing.
Caution: Needle length may not be ideal for all injection routes; confirm the required needle length for your procedure before purchase.
Buying Guide: Choosing the Right 1/3 ml Syringe
- Capacity and graduation readability: For precise dosing, opt for 0.3 ml syringes with bold, clear graduations. Readability reduces the chance of dosing errors.
- Needle gauge and length: 31G is common for small-volume injections. Lengths around 8 mm or 6 mm suit many applications, but longer or shorter options exist for specific solutions or access needs.
- Packaging and sterility: Individually wrapped syringes reduce contamination risk, especially in shared environments or field work.
- Bulk vs. mid-size packs: Large boxes provide cost efficiency for high-volume use, but mid-size packs can help manage inventory and space in smaller offices.
- Material and durability: Look for syringes constructed from compatible plastics with smooth plungers to minimize resistance and dosing error.
- Use-case alignment: Choose based on whether you need one-handed operation, portability, or compatibility with specific solutions and viscosities.
Frequently Asked Questions
- What is the typical use for a 1/3 ml syringe? It is commonly used for precise, small-dose injections or measurements in medical, veterinary, or laboratory settings.
