Foosi U-100 1ml Syringes with 31G 5/16 inch Needles — 100-Pack, Sterile Ultra-Fine Precision

Foosi U-100 1ml syringes with 31G 5/16" needles are a 100-count set of individually sterile, ultra-fine disposable syringes designed for precise small-volume dosing and laboratory or home use.

These Foosi U-100 1ml/cc syringes pair a clear, easy-to-read barrel with an ultra-fine 31 gauge (5/16 inch / 8 mm) needle, supplied in a value-packed box of 100. Each unit is individually sealed after ethylene oxide sterilization to protect cleanliness and maintain integrity until first use. Built for accurate measurement and smooth plunger action, they are intended for non-professional applications such as scientific experiments, hobbyist projects, or routine at-home tasks that require precise liquid handling.

How accurate and easy to read are the Foosi U-100 1ml markings?

The barrel features clear, molded graduations calibrated to 100 units (1ml/cc) so you can measure small volumes reliably. The plunger and barrel are engineered for close tolerances to reduce residual liquid and maintain consistent dosing with minimal effort.

• Clear printed or molded unit markings for quick reading
• High piston-to-barrel tightness minimizes leakage and residue
• 1ml capacity with 100-unit scale for precise small-volume work

What makes the 31G 5/16" needles suitable for delicate applications?

At 31 gauge and 5/16 inch length (approx. 8 mm), the needles are ultra-fine and designed to pass through small openings or deliver micro-volumes with minimal disturbance. Their thin profile reduces flow resistance for better control when handling low-viscosity liquids.

• 31G ultra-fine diameter for minimal disruption
• 5/16 inch (8 mm) length for shallow, controlled delivery
• Protective caps included to guard sterility before use

Are these syringes safe and sterile out of the box?

Each syringe is sterilized using ethylene oxide and individually sealed to preserve sterility until opened. Components use non-toxic materials and rubber parts selected to provide durability and consistent performance under normal use conditions.

• Individually sealed after ethylene oxide sterilization
• Non-toxic materials with secure plunger fit for airtight operation
• Single-use disposable design reduces contamination risks

How much value does the 100-pack offer for frequent users?

The 100-count configuration gives ample supply for repeat projects, routine replacements, or group work, reducing the need to reorder frequently and lowering per-syringe cost. Bulk packaging also helps avoid shortages when consistent availability matters.

• 100 syringes per box for extended use or group settings
• Cost-effective option for routine and repeated tasks
• Compact storage-friendly box keeps supplies organized

Who is this for: Foosi U-100 1ml syringes with 31G 5/16" needles are intended for people who need accurate small-volume liquid dispensing outside of clinical settings — hobbyists, laboratory technicians in non-clinical labs, craft and DIY users, and anyone performing scientific experiments, calibration, or product sampling. These syringes are not supplied for professional medical procedures; they are designed for single use in industrial, laboratory, educational, or home environments that require sterile, precise micro-dosing and easy disposal.
