Foosi U-100 1ml Syringes with 31G 5/16-inch Needles — 100-Pack, Sterile Individually-Sealed, 100‑unit Scale

Foosi U-100 1ml syringes with 31G 5/16-inch needles are a 100-count pack of individually sterile, disposable syringes designed for precise small-volume dispensing in labs, industrial settings, and home projects.

These Foosi U-100 syringes combine a 1 ml/1 cc barrel scaled in 100 units with ultra-fine 31-gauge, 5/16" (8 mm) needles, supplied in a bulk 100-pack for routines that require frequent single-use syringes. Each syringe is individually sterilized and sealed to preserve cleanliness. The smooth piston action and clear, accurate graduations make them suitable for controlled measurements of small liquid volumes for experiments, DIY tasks, or non-professional applications.

How accurate and easy to read are the 100-unit markings?

The clear barrel printing provides a readable U-100 scale, allowing fine measurement of small doses and liquids. The piston fits tightly to minimize residual volume and ensure consistent delivery when drawing or dispensing fluids.

• 1 ml/1 cc barrel graduated in 100 units for precise measurement
• High-contrast markings for quick visual checks
• Smooth piston-to-barrel fit reduces leftover liquid
• Disposable single-use design prevents cross-contamination

Are the needles and syringes sterile and safe for handling non-medical tasks?

Each syringe is individually sealed after ethylene oxide sterilization to maintain sterility until opened. While they meet cleanliness and quality standards for lab and industrial use, they are labeled not for professional medical use—ideal for science projects, sampling, adhesive application, or other non-clinical tasks.

• Individually sterile-sealed packaging for single-use hygiene
• Manufactured from high-quality plastic and rubber components
• Non-toxic and odorless materials for safe handling
• Disposable to reduce contamination risk in repeated workflows

How fine are the needles and what applications suit 31G 5/16"?

The included 31-gauge needles are extremely fine and short (5/16" / 8 mm), offering minimal puncture size and precise surface-level delivery. These needles are well suited to controlled micro-dispensing, collecting small samples, or applying adhesives and reagents where a delicate touch is important.

• 31G ultra-fine needles for minimal penetration and precise drops
• 5/16" (8 mm) length offers control for superficial applications
• Suitable for lab sampling, craft adhesives, and equipment priming
• Needles include caps for safe transport and storage

What makes the 100-pack a practical choice for frequent users?

Buying a 100-pack reduces the need for constant reordering, lowers per-unit cost, and provides a ready supply for tasks that require many single-use syringes. It also supports organized workflows by ensuring a consistent stock of sterile syringes on hand.

• Bulk 100-count reduces cost per syringe for regular use
• Individual sterile packs simplify inventory and quality control
• Good for labs, makerspaces, hobbyists, and light industrial tasks
• Compact box storage keeps supplies accessible and protected

Who is this for: The Foosi U-100 1ml syringes with 31G 5/16" needles are made for researchers, educators, hobbyists, and technicians who need accurate, single-use micro-dispensing tools that are sterile and easy to store. They are intended for non-professional or non-clinical uses such as laboratory sampling, science experiments, precise adhesive application, equipment maintenance, or other tasks requiring careful measurement of small liquid volumes.
