The Destroyer BD-300B is capable of melting the needle almost immediately with low voltage electric shock (AC/DC). The syringe body can be liquefied with mechanic cutting which offers double super heating protection. The additional liquid in the syringe is removed immediately without pollution. Some normal electrical spark can occur during melting. It has an indicator which offers light sparks at the time of melting to inform, that needle is under destruction. The full process ends within 1-3 seconds. It runs on power (AC 110V±10%/220V±10%; DC 6V). It melts by mechanic cutting with low pressure and high temperature. Taking 20ml syringe body as reference, it can melt syringe (ø1.2mm length 35mm) approximately in 3 seconds and abolish the body within 4 seconds. It can destroy 240 needles continuously taking 20ml syringe body as reference. It creates noise less than equal to 50 decibel. Besides having AC 8V working voltage for electrode chip with power less than equal to 130VA. Its electrode chip superheating protection temperature is 85?.
