Solo una suposición a partir de la referencia que te adjunto más abajo. En ella hablan de robots que pipetean muestras automáticamente. El "dive out" es la velocidad con que se retira la pipeta una vez liberada la muestra dentro del vaso de precipitados:

As is the case with most pipetting robots, it is also possible, in the case of BEP 2000, to change software settings in what is termed the "System Setup" in order to change the physical characteristic values for sample uptake and release.

Examples of such settings which were selectively modified within the meaning of the present invention in the case of sample uptake (aspirate profile, see FIG. 5) are: "Start velocity" describes the initial velocity of sample uptake; "Top velocity" describes the maximum velocity of sample uptake achieved; "Dive out velocity" describes the velocity with which the tip is moved out of the liquid following sample uptake.

Examples of such settings which were selectively modified within the meaning of the present invention in the case of sample release ("dispense profile", see FIG. 5) are: "Start velocity" describes the initial velocity of sample release; "Top velocity" describes the maximum velocity of sample release achieved; "Acceleration" describes the acceleration of sample release; "Cutoff velocity" describes the acceleration velocity when sample release is terminated (cutout velocity when the operation is terminated); "Dive out velocity" describes the velocity with which the tip is moved away from the position above the reaction vessels following sample release.

Bueno, también se refiere a la velocidad con que se retira la punta de la pipeta del líquido una vez extraída la muestra.

O sea, la "dive out velocity" es la velocidad con que se retira la punta de la pipeta, tanto al extraer la muestra como al liberarla.

Así que cambio mi traducción a "velocidad de retirada de la (punta) de la pipeta.
