If you are a primary care physician you treat warts regularly. Many of us prefer to use liquid nitrogen which we store in a canister and is replenished every few weeks. We siphon the liquid nitrogen into an insulated spray bottle which we use to freeze warts. Usually the spray bottles are 10 or 16 ounces and somewhat unwieldy to maneuver. Because the liquid nitrogen slowly evaporates, you end up wasting a lot of liquid nitrogen.
I have become a fan of Brymill’s Cry-Baby 150 ml spray canister. It fits nicely in the palm in the hand, and lets you direct the spray precisely. This means you can freeze the wart with a discreet margin and avoid freezing tissue unnecessarily. It come with nozzles of different size openings, and Brymill sells cones and plastic disks for isolating the wart from the surroundingtissue.
Additionally because of it’s small size you don’t waste liquid nitrogen and you will be replenishing your liquid nitrogen supply less frequently. It sells for approximate $600 and is a worthwhile investment in your practice.
