A table top liquid-liquid extraction unit was constructed.  The project also involved the repair and servicing of peristaltic suction pump, by painting it, replacing the connecting cord to the power supply, refilling of the work out suction plates, teeth and general servicing of the equipment.  The glass absorption columns were provided as well as two yards length of transparent, soft, translucent synthetic chemical rubber (hose).  The two ends of the pipe were connected to glass absorption columns at their base outlet, a clip was also provided to stop the flow of liquid through the lose whenever it desired.  

Two conical flask of about 250ml in volume was also provided.

The repairs and servicing was made so that the suction pump may be capable of transporting liquid from are glass absorption column to another.
