Treating shallow lesions with a liquid nitrogen spray
The Wallach Ultrafreeze Liquid Nitrogen Spray
This instrument is designed to hold 300ml or 500ml of liquid nitrogen for 12-24 hours, during which time evaporation takes place continuously. For best results, the liquid nitrogen (at -160°C) is sprayed directly onto the lesion through one of a variety of spray apertures.
Liquid nitrogen is particularly effective for larger shallow lesions and suited for many dermatological conditions.
For confined lesions such as warts, a variety of closed tips are available but the results are less satisfactory than with the Wallach LL100 which permits controlled freezing to greater depths.
