It is controlled by an electrical or electronic timer. The paraffin bath temperature ranges from 50-65 degrees centigrade and is agitated. The fumes are removed by an integral fume collecting system. The process time/step is adjustable between 15 minutes to 24 hours. The drain time/step is 0 to 1 minute. Used to fix, dehydrate, clear and infiltrate tissue specimens to preserve the integrity of their cellular components for light microscopy.
