Compatible with the popular LL100, LLCO2, and WA1000B Cryosurgical systems, these tips deliver fast, precise freezing for cryosurgical procedures. The Wallach Cryosurgical Tips have a disposable shield that can be removed from the tip and discarded after each use, which allows the tool to be sterilized. It's recommended that users avoid soaking the tips, in order to avoid tip corrosion. Shields are reapplied with each procedure, which insulate tips and assure proper attachment of the tip by serving as a positive stop.
