The Econo Sterile Pederson Vaginal Speculum is a gynecological instrument used for performing pelvic examinations, Pap Smears, and examining the cervix. It is a double blade duckbill speculum inserted with the blades closed. The blades are then opened by an external lever and screw. The blades of the Pederson Speculum are more narrow than the blades of the Graves Speculum. The practitioner can best determine which type and size speculum is most appropriate for the patient. Econo Sterile instruments are ready-to-use, sterile, disposable, floor-grade instruments sold in bulk quantities. This product is a large sized speculum. It is sold in cases of 25.
