VEU-Vacuum embedding unit


The vacuum embedding unit has been developed for impregnating porous and fragile specimens with an adequate bonding material that fills pores, cracks and prevents fracture. Up to 10 specimens can be processed sequentially without disrupting the vacuum. The former are placed on a rotating plate in individual moulds inside the vacuum chamber. A silent electrical vacuum pump, a pressure gauge and a vacuum regulating valve generate and maintain the vacuum. Once the latter condition established, the moulds are successively brought under the resin’s feeding nozzle and filled using a resin dispenser. This component consists of a disposable plastic cup which contains the resin, a disposable plastic tube that channels the resin, a rubber stopper ensuring effective sealing and a ball joint allowing the tube to be manipulated and orientated inside the chamber. A lamp helps to monitor the extraction of bubbles from the resin. The glass chamber prevents strong resin adhesion, therefore facilitating maintenance and cleaning.
