JOINAP 1ml Syringes 31G 5/16" — Pack of 100, Individually Sealed for Precise Micro-Dosing

JOINAP 1ml 31G 5/16" syringes are single-use, individually sealed syringes engineered for precise, low-volume liquid delivery.

These syringes combine an ultra-fine 31-gauge, 5/16" needle with a clear, graduated 1ml barrel and a smooth, leak-resistant plunger. Supplied in a pack of 100, each unit is individually wrapped for sterile handling and easy storage. They are designed for any task that needs accurate micro-dosing, neat dispensing and minimal waste.

How accurate is the volume control on these 1ml syringes?

The clear barrel shows readable graduations for exact measurements, while the tight-fitting plunger reduces backflow and drip. The small 1ml capacity is ideal for fine dosing where every microliter counts.

• 1ml marked barrel for precise small-volume dosing
• Fine 31G needle minimizes dead volume
• Smooth plunger action for controlled dispenses
• Leak-resistant fit helps prevent loss between draws

What liquids and applications are these needles suited for?

JOINAP's 31G 5/16" configuration works well with a wide range of low- to medium-viscosity fluids where precision matters. Use them for measured delivery of laboratory reagents, adhesives, flavorings, essential oils, ink refills, or any application requiring careful micro-dosing.

• Compatible with aqueous solutions, alcohols, thin oils and other low-viscosity liquids
• Useful for lab work, crafts, electronics repair and cosmetic samples
• Fine gauge reduces surface disruption on delicate targets
• Single-use, sterile packaging supports contamination control

How do these syringes support hygiene and storage?

Each syringe is individually sealed to preserve sterility until use, simplifying inventory and minimizing cross-contamination risk. The compact, stackable pack of 100 keeps supply organized and easy to access in busy workflows.

• Single-sterile packaging per syringe for safer handling
• Pack of 100 reduces frequent reordering and downtime
• Durable plastic construction resists bending and leaking in storage
• Clear labels and visible markings make identification quick

How easy are they to use for controlled dispensing tasks?

The combination of a narrow 31G tip and a smooth, tight plunger gives predictable, steady flow with minimal force. Users can apply consistent pressure to release small amounts without sudden spurts, improving repeatability across multiple doses.

• Low-resistance plunger provides tactile control during dispensing
• Fine needle tip supports micro-droplet placement and precise lines
• Short 5/16" needle balances control with reduced flex
• Clear volume markings enable quick visual readouts

Who is this for: JOINAP 1ml 31G 5/16" syringes are for professionals and hobbyists who need accurate, small-volume liquid delivery with hygienic, single-use convenience. They fit laboratory technicians, medical-support staff, cosmetic formulators, electronics repairers, craftspeople, and anyone who dispenses adhesives, dyes or fluids where precision and cleanliness matter. The 100-count, individually sealed format is suited to busy workstations and bulk storage while preserving the integrity of each syringe until use.
