Key Advantages of Dispensing Syringe

Adhesive syringe satisfies material compatibility with specific piston designs and flexible integration across manual dispensing tasks.
  • Chemical-Resistant Polypropylene: PP is generally inert to aggressive solvents and oils under normal conditions.
  • Specific Piston Designs: Rubber pistons provide smooth, virtually leak-free operation. All-plastic pistons reduce the risk of elastomer contamination.
  • Piston Options for Different Fluids: Rubber pistons typically provide tighter sealing for lower- to medium-viscosity fluids. All-plastic pistons reduce elastomer contact when contamination sensitivity matters.
  • Capacity Range for Manual Work: Small barrels help you control low-volume dosing. Larger barrels reduce refill frequency when precision still matters but throughput is higher.

How to Choose Dispensing Syringe

  • Piston Type: For high-viscosity fluids, rubber pistons provide the necessary sealing force. For applications involving silicone-free fluids or high-purity optical components, plastic dispensing syringes are preferred.
  • Outlet Type: If you require more recise flow control, please choose a luer-lock dispensing syringe. If you prefer lower resistance, a tapered syringe is the better choice.
  • Production Cycle: Match capacity to refill frequency to minimize downtime and fatigue. Please select the syringe based on your application.

Frequently Asked Questions About Dispensing Syringe

Which piston works better for low-viscosity adhesive in a dispensing syringe?

−

A dispensing syringe with a rubber piston is suitable for low-viscosity adhesives. It maintains consistent seal pressure, prevents blow-by, and provides smooth flow. Avoid rigid pistons, as they allow fluid to bypass under pressure. Always match piston design to material viscosity per manufacturer recommendations.

Can I use a luer-lock dispensing syringe for high-viscosity materials?

How do I choose syringe capacity for adhesive without frequent refilling?

+

Can a dispensing syringe be used for long-term storage of industrial adhesive?
