Features:
AC; low voltage electric shock can melt the needle instantly; mechanic cutting can melt syringe body, double superheating protection is provided;
Surplus liquid in the syringe can be boiled off instantly and no pollution;
There will some electrical spark which is normal during melting;
Indicator light sparks during melting, showing the needle is under destroying, the whole process is finished in 1 to 3 seconds.
