Multi Core Extruders

This basic extruder works by pushing the multicore sample tube over a stationary plunger. Steel stopper rods can be placed at 1/2 centimeter intervals to measure extruded intervals. Polycarbonate sample rings can also be used to measure extruded sediment quantities.

This multicore extruder moves a piston up through a stationary multicore tube. It moves 1 mm for each full revolution of the handle. The sample tube is mounted in place still inside the frame. It can also be quickly retracted or extended with a 3/8 drill extension.
