dropping box

Non-PRO English to Spanish Tech/Engineering Chemistry; Chem Sci/Eng final report, sample test, chemistry, tap density
I can't find the translation of this part of the equipment used in a tap density test of a sample. The test tube is raised and dropped vertically onto a rubber pad at a distance of 2.5 cm a total of 50 times.

caja de fondo(in this context)

Golpeteo manual
Esta caja tiene pequeñas dimensiones porque el hueco por donde pasa el polvo en el fondo del tubo de vidrio graduado en muy pequeño. La base del tubo ensayo es grande comparado con el hueco de la caja de fondo.

(ii) by constraining the upwards distance traveled and allowing free-fall of the cylinder under gravity (drop box).
A drop box has a hole in its lid, large enough for the body of the graduated cylinder to pass though it, but too small for the base of the cylinder
