The WA1000B™ console offers the ideal combination of easy-to-use controls and built in safety features. It uses the powerful LL100™ two-trigger freezer for Nitrous Oxide. (Carbon Dioxide units are designed differently due to the properties of the gas.) Freeze and defrost only occur when triggered and can be stopped instantly. A console-mounted switch must be activitated to permit gas to flow into the LL100™ and a color-coded gauge provides gas pressure reading at a glance. The Temperature Indicator gives surgeons unparalleled control and efficiency during cryosurgery. A large selection of reusable sterilizable cryotips and disposable plastic shields are available.
