SciMed Cryo Pro — hand-held liquid nitrogen (LN2) cryosurgery sprayer for dermatology cryotherapy. Uses liquid nitrogen at -196°C — dramatically colder than CO₂ (-79°C) or N₂O (-89°C) cryoguns, delivering 1/3 the freeze time to achieve equivalent tissue destruction. Includes 6 interchangeable freeze heads for lesion-size matching. Portable, single-handed operation, no anesthesia required. Instant freeze via direct LN2 release onto internal metal probe wall. ISO 13485:2016 certified. 3-year manufacturer warranty. $499.99 direct.

Clinical applications
- Skin tumors + malignant BCC (basal cell carcinoma) — definitive cryotherapy where LN2 is standard-of-care
- Warts (verruca vulgaris, plantaris, plana) — hands, feet, face, high-volume workflow
- Actinic keratoses (AK) — sun-damage premalignant lesions
- Skin tags (acrochordons) — neck, axillae, groin
- Molluscum contagiosum — viral papules
- Seborrheic keratoses — stuck-on benign lesions
- Small superficial SCC — with appropriate dermatology + margin planning
- Cherry angiomas + small vascular lesions
- Field cryotherapy — multi-AK-lesion sun-damaged field
Specifications

| Freeze mechanism | Direct LN2 release onto internal metal probe wall which contacts the lesion (instant freeze) |
| Freeze heads | 6 interchangeable (varying orifice + tip sizes for lesion-size matching) |
| Design | Hand-held, single-handed operation, portable between consulting rooms |
| Anesthesia | No anesthesia required for typical dermatology cryotherapy |

| Warranty | 3-year manufacturer warranty |
Where to source liquid nitrogen
- Industrial gas suppliers — Airgas, Linde, Praxair, Matheson (LN2 dewar rental $50-100/mo + refills $0.30-1.00/liter)
- Hospital pharmacy — internal transfer if you're hospital-affiliated
- University medical research supply — often accessible if near an academic medical center
- Veterinary supply distributors — some carry LN2 for reproductive medicine

FAQ
Should I choose LN2 or CO₂/N₂O cryogun?
LN2 for definitive skin cancer cryotherapy + high-volume dermatology (faster freeze cycles). CO₂/N₂O for cervical cryotherapy + ENT + multi-specialty practices where speed matters less than gas availability. If you're building a dedicated skin cancer + dermatology practice, LN2 is standard-of-care.
Why is this 3-year warranty vs 1-year on other cryoguns?
LN2 cryoguns have simpler internal mechanisms (LN2 dewar + probe contact vs pressurized gas systems with valves + seals). Lower failure rate justifies 3-year warranty. ISO 13485:2016 certification also reflects premium manufacturing QC.
Does LN2 need refilling during a session?
Depends on reservoir size. This mini cryogun has a smaller reservoir than the 350ml Mini Cryogun ($499 direct competitor) — expect 15-30 procedures per fill for typical dermatology workflow. Boil-off between sessions is typical (LN2 evaporates ~30 mL/hour at rest).
How does this compare to Brymill / Wallach LN2 cryoguns?
Feature parity on essentials — LN2 dewar, 6 interchangeable freeze heads, hand-held portable design, -196°C tip temperature. Brymill Cry-Ac Tracker has electronic timer + temperature display. Price differential: $499 vs $1,100-$1,500 for Brymill. For 90%+ of dermatology practices, SciMed delivers full utility at 30-45% of Brymill pricing.
What's the warranty?
3-year manufacturer warranty covering all components. Consumables (freeze heads, O-rings) covered 6 months. Industry-leading warranty for dermatology cryogun.
