Our exclusive Ultima Needle Recapper offers complete one-handed operation. Simply insert needle sheath into the recapper until it clicks. The spring clamp automatically grips and holds it firmly while you uncap with one hand. Return the syringe for safe one-handed recapping and storage between injections. Once the procedure is complete and the syringe has been unscrewed from the hub, invert the recapper and press the button to eject needle with sheath directly into your sharps container. Non-slip 1 1/2" diameter base conserves tray space. Heavy 292g stainless steel construction provides ample stability. Steam autoclavable.
