Specifications : 

1.  CARDIOTECH ESU pencil tip is TEFLON coated which helps in reducing the tissue  build-up on the pencil tip. Hence scrapping & inconvenient delays are avoided. 
2.  PTFE coated cautery tip helps to equally distribute current over the entire surface of  the blade to create consistent & even coagulation. 
3.  PTFE coatings do not peel or flake during electrosurgical procedures.
4.  CARDIOTECH ESU pencil tips feature a HIGH-TECH PTFE COATING which reduces eschar build-  up during surgery, reducing the need for higher power settings, & minimizing the likelihood of injury  to surrounding tissues. 
5.  These blades can withstand temperature of 150 degrees hotter. 
6.  PTFE coated blades are stable & resistant to abrasions & can be wiped clean with a sterile sponge  without damaging the blade.
