A device (11) for filling and priming syringes (71), the device comprising:

• a support base (13);
• an engagement seat (15) defined on the support base (13) in order to receive the rear end (73) of the syringe barrel (75) of a syringe (71) provided with a sliding plunger (77);
• engaging means (17) defined at the engagement seat (15) and adapted to cooperate with the syringe barrel (75) for firmly holding the syringe (71) associated to the engagement seat (15);
• a first vacuum pump or compressor (23) which is provided with a suction opening (23a) communicating with the engagement seat (15) and is adapted to generate an under-pressure in the volume (29) comprised between the plunger (77) of the syringe (71) and the engagement seat (15) when the syringe is firmly engaged in the engagement seat (15);
• and
• a second vacuum pump or compressor (24) which is provided with a discharge opening (24b) communicating with the engagement seat (15) and is adapted to generate an over-pressure in the volume (29) comprised between the plunger (77) of the syringe (71) and the engagement seat (15) when the syringe is firmly engaged in the engagement seat (15).
