Dispensing Syringe

Rubber-sealed pistons offer superior sealing, while non-rubber plastic pistons eliminate the risk of contamination for high-purity applications. Rubber-sealed pistons provide superior airtightness and smoother travel for high-viscosity adhesives, sealants, and greases. They prevent backflow and air ingress during manual operation. Non-rubber (All Plastic) pistons avoid the risk of silicone oil and elastomer contamination, for high-purity solvents, optical-grade fluids, and sensitive semiconductor processes where material integrity is paramount.

You should select a dispensing syringe capacity based on the required dosage precision and the frequency of refills to balance operator fatigue with process control. Small barrels (1cc to 5cc) are intended for high-precision micro-dosing and gemstone setting where drop-level accuracy is critical to prevent overflow on expensive components. Mid-range sizes (10cc to 30cc) serve as the industry standard for PCB rework and general electronics bonding, offering enough volume for a full shift without excessive weight. Large syringes (50cc to 500cc) are reserved for bulk applications like potting, crack injection, or machinery lubrication to minimize downtime caused by frequent refilling. Note that larger manual syringes require significantly more hand force; for high-viscosity materials in 50cc+ barrels, we recommend pneumatic assistance to ensure consistent flow and safety.

Industrial dispensing syringes are designed as application tools for active production and should not be used as primary long-term storage containers for adhesives. While our high-grade PP resists most industrial solvents, oxygen-sensitive or UV-reactive chemicals can degrade or cure when left in a non-hermetic syringe barrel for extended periods. Most industrial adhesives require specialized aluminum tubes or nitrogen-purged cartridges for long-term shelf-life stability. Using these non-sterile industrial syringes for medical or food storage is strictly prohibited due to potential chemical migration.

Yes, we provides customized dispensing syringe solutions including specific barrel colors, custom branding, and specialized outlet geometries for R&D and large-scale industrial projects. We support the prototyping phase by offering sample across our 1cc to 500cc range to verify chemical compatibility before you commit to bulk procurement. For specialized production lines, our engineering team can modify barrel tolerances or develop UV-opaque black barrels for light-sensitive materials. As a direct manufacturer, we provide stable lead times for custom runs, though all units remain non-sterile and intended for industrial fluid control only. Minimum order quantities typically apply for non-standard colors or custom-labeled packaging.
