Asepto Syringe

Asepto Syringe

<< >>
Usage conditions apply
The Asepto was advertised as a plungerless all-glass syringe with a closely fitting rubber bulb of exactly the same capacity as the barrel of the syringe, so that the syringe is filled or emptied with one compression of the bulb. The bulb slips into, not over, the barrel of the syringe, making sterilization easier. And the form prevented "fluid from entering the bulb when the syringe was inverted.” The inscription on this example reads "ASEPTO NO 3035 / Becton Dickins & Co."
The form was devised by Oscar O. R. Schwidetzky (1875-1963), a German-born instrument maker who served an apprenticeship before emigrating to the United States. In time, Schwidetzky became director of research at Becton, Dickinson & Co.
