Abstract

Una pipeta (10) ajustable incluye un cuerpo (12) que contiene un ensamble (14) de embolo que incluye un boton (22) de pulgar que se mueve axialmente en carreras de distribucion relativamente mas largas y de aspiracion de muestras relativamente mas cortas alternativamente. La ranura (108) de guia en un manguito (32) de guia reciben un perno (52) de parada portado por un eje (48) de embolo, y las ranuras (108) definen dos topes (104, 106) inferiores axial y circunferencialmente separados para carreras de aspiracion y distribucion respectivamente. El boton (22) de pulgar incluye lobulos (112, 114) de desplazamiento que aplican una fuerza de torsion rotacional al eje (48) de embolo cuando se presiona por el usuario. El usuario presiona un lobulo (112) para una carrera de aspiracion para girar el eje (48) de embolo en una direccion y alinee el perno (52) de parada con el tope (104) inferior en la posicion superior para una carrera de aspiracion relativamente mas corta y el usuario presiona el otro lobulo (114) para que una carrera de distribucion gire el eje (48) de embolo en la otra direccion y alinee el perno (52) de parada con el tope (106) inferior en la posicion inferior para una carrera de distribucion relativamente larga. Una ventana, (116) en el cuerpo permite que el usuario vea y con esto entienda la funcion del mecanismo de seleccion de parada inferior.
