The smallest HPLC Pump in the world with a 10 ml or 50 mL pump head.
The K-120 is an isocratic HPLC pump to deliver an eluent or eluent mixture. It is suitable to be used as a dosing pump (e.g. for derivatization). The instrument does not have a pressure display; however, it does have an automatic shut-off function if the pressure reaches over 400 bar. A manometer can be ordered separately as an accessory. The 10 ml head is also availiable with titanium inlays.
