When the instrument touches tissue, coagulation starts automatically after a specified period of time. Areas of use All bipolar coagulation procedures in which you want to coagulate vessels fast and effectively or want to replace monopolar forceps coagulation. Difference from BIPOLAR SOFT COAG Suitable electrodes Technical data 100 / 170 Fast bipolar coagulation. Faster bipolar coagulation. Carbonization of the tissue cannot be precluded. Bipolar instruments, e.g. bipolar forceps, bipolar hook electrodes. HF voltage waveform pulse-modulated sinusoidal alternating voltage Rated frequency 350 kHz (at RL= 500 ohms) ± 10% Crest factor 3.8 (at RL = 500 ohms) Rated load resistor 200 ohms Max.
