Abstract: A drill cuttings sample washer according includes a frame-mounted wash bath and degreaser bath. A slide bar is mounted across one end of the frame and adjacent the baths. A spray arm is mounted on the slide bar. Sieve holders are mounted in the baths. A vibrator vibrates at least the degreaser bath. The spray arm is slidably and pivotably mounted on the slide bar. The spray arm pivots for selective raising and lowering of the spray arm from a lowered position over the wash bath to an elevated position allowing access into the bath. Samples contained in mesh-bottomed sample sieves are mountable into each of the sieve holders.
