otwooi 1ml Disposable Syringes 31G x 6mm — 100-Pack, Fine-Gauge Micro-Dosing with Caps

otwooi disposable syringes are precision plastic syringes in 0.5ml and 1ml sizes with ultra-fine 29–31G needles and protective caps, sold in a 100-pack for labs, hobbyists, and light industrial use.

These syringes combine compact volume, fine-gauge needles, and clear graduated barrels to deliver accurate micro-dosing, sample transfer, and glue or liquid dispensing. Each unit is individually sealed to preserve sterility for handling non-critical lab tasks, craft projects, and maintenance jobs. Available needle gauges and lengths include 31G (6mm and 8mm) and 30–29G (12.7mm), in both 0.5ml and 1ml barrel sizes, giving you options for shallow or slightly deeper delivery while keeping fluid control tight.

How precise are these syringes for small-volume dispensing?

They’re designed for micro-volume work: clear, printed graduations and a smooth plunger let you measure and deliver small doses consistently. The fine-gauge needles reduce dead volume and improve control when working with viscous liquids or low-volume samples.

• Graduated 0.5ml and 1ml barrels for accurate readouts
• Fine 29–31G needles minimize fluid retention
• Smooth plunger movement for steady, even dispensing

Which gauge and needle length should I choose for my task?

Select gauge and length based on penetration depth and flow rate needs: 31G with 6mm or 8mm needles suits shallow injections and precise surface dosing; 30G or 29G with 12.7mm reaches slightly deeper areas and handles marginally higher flow. For adhesives or thicker liquids, larger internal diameters and a slower push give better results.

• 31G x 6mm: best for very shallow, precise surface work
• 31G x 8mm: slight increase in reach with same fine control
• 30–29G x 12.7mm: longer reach for deeper access and small reservoirs

Are these syringes safe and ready to use out of the package?

Each syringe is individually sealed to reduce contamination risk until use; caps protect needle tips during storage and transport. They are intended for laboratory, craft, adhesive injection, and similar non-implantation uses—follow local protocols for disposal and avoid reuse when sterility is required.

• Individually packaged syringes with protective caps
• Clear markings help avoid dosing errors
• Dispose after single use in accordance with regulations

How do these syringes perform with glues, fragrances, or plant nutrients?

These syringes are versatile for non-medical applications: the fine tips and clear measurement scale make them excellent for injecting adhesives into tight joints, measuring essential oils or e-liquids, and dosing liquid nutrients for plants. Viscous materials may require slower plunger pressure or a larger gauge for best flow.

• Accurate small-quantity dosing for adhesives and pigments
• Good for transferring perfumes, e-liquids, and lab reagents
• Works for pet-care and plant-feeding tasks where small volumes matter

Who is this for? These otwooi syringes suit hobbyists, technicians, and researchers who need reliable small-volume delivery without bulk equipment—ideal for electronic vaping maintenance, arts and crafts involving pigments and adhesives, basic lab sample handling, and precise dosing tasks for pets or plants. They are not for surgeries or invasive medical procedures; choose these when you need inexpensive, individually wrapped syringes for repeatable micro-dispensing and safe needle protection.
