Gesanghua U-100 0.5cc Insulin Syringes 30G 5/16" 100-Pack — Individually Sealed, Clear Barrel

Gesanghua U-100 0.5cc (30G, 5/16") syringes are single-use, individually sealed insulin-style syringes sold in a 100-pack for precise small-volume dosing and non-medical laboratory tasks.

These compact 0.5cc/0.5ml syringes from Gesanghua combine a fine 30-gauge needle with a short 5/16" length, delivering accurate small-volume measurements in a lightweight, disposable format. Each syringe arrives individually wrapped to maintain cleanliness until needed. Designed for hobbyist, household, and laboratory uses where low-volume accuracy matters, they offer clear volume markings, a smooth plunger, and economical bulk packaging.

How accurate are these syringes for small-volume dosing?

The syringes include clear, well-printed measuring marks on the barrel, making it easy to measure down to fractions of a milliliter. Their 0.5cc capacity keeps readings focused on low-volume tasks, reducing waste or overfill when you need small, consistent amounts.

• 0.5cc / 0.5ml maximum capacity with incremental markings for precise dosing
• Clear plastic barrel for unobstructed view of liquid level
• Smooth plunger action to help steady delivery
• Fine 30G needle and short 5/16" length suitable for small-volume, shallow injections or transfers

Are these syringes sterile and packaged for single use?

Yes — each syringe is sealed in its own package to protect it from contamination until opened. The individual wrapping supports single-use practices and keeps unused syringes clean in storage, which is especially helpful for labs, DIY projects, and pet or plant care tasks.

• Each syringe individually sealed to reduce exposure to contaminants
• Packaged quantity: 100 pieces per box for convenient bulk supply
• Easy-to-store flat-packed design to save space

What are safe and appropriate uses for these syringes?

These syringes are intended for non-professional applications such as home care for pets, hobby lab work, gardening nutrient measurement, arts and crafts, or controlled fluid transfers where small volumes are required. They are labeled "not for professional medical use," so avoid clinical or human medical applications.

• Administering measured liquid supplements or treatments to small pets (dogs, cats, birds) by trained caregivers
• Dispensing plant nutrients, concentrated solutions, or small-volume reagents in garden and lab projects
• Arts, crafts, and precise glue or dye application where fine control is needed
• Science experiments and hobbyist testing that do not require certified medical-grade devices

How do I choose the right size and needle for my task?

Pick the 0.5cc (0.5ml) size when your doses are very small and accuracy matters; the 30-gauge, 5/16" needle suits shallow or delicate delivery needs. If you need a thinner needle or smaller increments, compare gauges and capacities — Gesanghua also lists other sizes for different applications.

• Choose 0.5cc for doses under 0.5ml and frequent small-volume applications
• 30G needle balances a fine bore with reasonable flow for viscous liquids
• 5/16" needle length limits penetration depth for shallow delivery or surface applications
• Review alternative sizes (e.g., 1ml 31G) for different flow and depth requirements

Who is this for: These Gesanghua 0.5cc 30G 5/16" syringes suit hobbyists, small-scale lab users, gardeners, and pet owners who need accurate, low-volume liquid handling without clinical medical certification. They are useful when cleanliness, single-use convenience, and fine measurement are priorities — provided you avoid professional medical or human clinical use, as indicated.
