Tungsten Alloy Syringe Shield

Our tungsten alloy syringe shields are radiation protective devices for nuclear medicine, designed for safe handling, dispensing and administration of radiopharmaceuticals such as F-18, Tc-99m, Lu-177. Made from high-density W-Ni-Fe tungsten alloy, lead-free and non-toxic, they replace traditional lead shielding with compact size, high mechanical strength and excellent gamma-ray attenuation performance.

We divide our syringe shields into 3 main categories by locking structure & application scenario:

Screw-Lock Tungsten Syringe Shield The thumbscrew locking design provides stable and firm clamping, preventing accidental release. Equipped with lead glass viewing window for clear reading of syringe scale and liquid volume. Widely used in PET, SPECT and high radioactivity dose preparation. Standard sizes: 1cc, 2cc, 3cc, 5cc, 10cc. Custom wall thickness available for higher energy isotopes.
Clip-Lock / Quick Release Syringe Shield One-hand quick clip locking mechanism, easy loading and unloading of syringes. Ergonomic slim body, easy to clean and decontaminate. Ideal for routine daily dose preparation in nuclear medicine departments. Optional color coded shells for quick size identification.
Bullet Type Tungsten Syringe Shield Integrated bullet-shaped tungsten alloy body without split lock structure. Smooth surface, anti-roll design, good durability. Compact lightweight construction, fit for transport and short-term storage of radioactive syringes. Suitable for low & medium activity radiopharmaceutical operations.
