Hamilton Model 725 N Microliter Syringe, 250 µL

The 700 series syringe is the original hand-fitted Hamilton syringe. Low-volume syringes with cemented needles (N) have the needles cemented into the glass syringe barrel at a point corresponding to the zero graduation mark. With this termination, dead volume is limited to the internal volume of the needle. These syringes are not autoclavable. The needle gauge is determined by the syringe volume and is not user-selectable. Syringe 60373-775 features a special cemented needle (SN) with a termination that is the same as a cemented needle termination, except it allows for a variety of user-defined gauges, lengths, and point styles to be attached. These syringes are also not autoclavable.
