Tungsten Syringe Shield with the same popular locking mechanism as the Unilock® I but with the whole of the tungsten barrel being made from tungsten, this gives increased shielding. There is also the added advantage of a wider lead glass window for increased viewing of the syringe graduations. The Unilock IV has a flat base to prevent rolling whilst in use.
Tungsten barrel thickness: 2mm - 4mm. Lead glass window: 6-8mm thick, 2mm Pb equivalent. The shield is available to suit all sizes and makes of syringes
