These are a series of adapters that convert a large hub removable needle (RN termination) syringe to a Luer connection. There are three different removable adapters for 250 µl and larger syringes.

The adapters convert the RN termination into either a Male Luer, Male Luer Lock or a Female Luer Lock connection. The adapter has a port inner diameter of 0,99 mm that allows for sample spiking through a syringe fitted with a 26 gauge needle or smaller.
