@ Prathapan,

The configuration depends on what kind of procedures the machine is going to be use for. Is it going to be used by Gynecology or Dermatology?

Wallach Surgical has a good product (we use an older model for our Women's Clinic) and you need to select the tips you will use. It runs on either N2O or CO2.

Another product is from Ascon Medical Products and the company is based in Chennai, India. The contact page is here.

good luck on your selection.
