Ruiskusuutinosasta

Ruiskusuutinosasta is a term used in Finnish to describe the distal component of a syringe nozzle assembly that interfaces with the syringe barrel and dispensing tip. In English-language references this part is commonly described as the syringe nozzle tip or nozzle assembly. The name combines ruisku (syringe), suutin (nozzle) and osa (part).

Construction and materials: Most ruiskusuutinosasta components are manufactured from medical-grade stainless steel or polymers such as polycarbonate or polyether ether ketone (PEEK). The design is typically compatible with standard Luer connectors (luer-slip or luer-lock) and is intended for sterilization by autoclaving or chemical sterilants.

Design and features: A ruiskusuutinosasta may include a distal tip with a defined inner bore for controlled fluid flow, a threading or locking interface for secure attachment to the syringe, and optional features such as integrated piercing pins for safety vents or surfaces treated to reduce shear stress on sensitive fluids.

Applications: They are used in pharmaceutical compounding, laboratory dispensing, microinjection, and medical administration systems where precise fluid delivery is required. The component is selected to match bore size, tip geometry and connector type to ensure reliable performance in a given workflow.

Variants and regulatory considerations: Variants differ by bore size, tip geometry and connector type. They are typically manufactured under sterile conditions and are often treated as single-use disposable components in many medical and laboratory settings to meet safety standards.
