20CC Tungsten Alloy Syringe Shield

Manufactured by Zhuzhou Jiuding Metal Technology Co., Ltd, this 20cc tungsten alloy syringe shield is a lead-free radiation protective device, specially developed for nuclear pharmacy, PET and SPECT laboratories to safely handle, dispense and transport radiopharmaceuticals loaded in 20cc syringes.

The shielding core is made of 95% tungsten alloy, with density of 18.1±0.15g/cm³.

· Outer dimension: Ø30.6 × 124 mm

· Inner dimension: Ø22 × 124 mm

· Shielding wall thickness: 2.8 mm

· Lead glass thickness: 5 mm

· Weight: 0.42 Kg per piece

As shown in the picture, the shield adopts white PTFE outer cladding over the tungsten substrate. PTFE material delivers good chemical resistance, easy radioactive decontamination and compatibility with routine medical disinfection. A long rectangular lead glass viewing window runs along the body, allowing operators to read syringe graduations and monitor the liquid level of radiopharmaceuticals along the full length of the 20cc large-volume syringe. It is equipped with a stainless steel end cap and knurled thumb screw locking mechanism. The knurled thumb screw can be tightened by hand without tools to firmly fix the syringe inside, preventing accidental sliding out during operation and transportation.

This high-density tungsten shield provides reliable gamma-ray attenuation for common radionuclides including F-18, Tc-99m and Lu-177. Custom service is available, such as non-magnetic tungsten alloy, customized dimensions, shielding thickness, window size and laser marking.
