Pipeta perfeccionada, que se caracteriza por el hecho de que en la parte posterior de la camisa por la que se desliza el émbolo, se ha previsto un escalón interior donde se asienta una junta tórica sometida a la compresión de un casquillo roscado a la pared del entrante que precede a dicho escalón, de manera que resulta fácilmente regulable el apriete del casquillo sobre la junta, para mantener la perfecta hermeticidad de ésta sobre el émbolo.
