Successful results of microwave polymerisation of different epoxy formulations have been reported in the literature. The present study was intended to shorten the time needed for polymerisation of epoxy resin by the use of a microwave technique. A standard double fixation and tissue processing was applied to samples of rat kidney tissue. Tissue samples from the control group were polymerised in a conventional oven at 60°C for 48 h, while tissue from the experimental group was irradiated in a microwave oven, initially at 900 W for 10 min and then at 360 W for another 100 min. During this irradiation, the sealed BEEM capsules were submerged in a water bath, so that the temperature rise was uniform and constant. This resulted in a homogeneous and rapid polymerisation. The cutting properties of the blocks in both groups were similar and no noticeable difference in the quality of the sections was evident when evaluated with TEM. The results showed that the use of a microwave oven reduced the time needed for the polymerisation of Epon blocks without any loss in quality.
