How long does 350ml last per session?
A single fill of 350ml LN2 typically supports 30–50 lesion treatments in a normal outpatient dermatology session (freeze times 5–20 seconds per lesion). Boil-off at rest is roughly 30ml/hour, so the working window from fill to empty is 4-6 hours during active clinical use.
Per-procedure math: if you treat 100 patients/month with 3-lesion average = 300 procedures = 6–10 refills = ~$3–5 in LN2 per lesion treated. Reimbursement for cryotherapy (CPT 17110–17111 for skin, 17000–17004 for AK) typically nets $80–150 per session. LN2 cost is trivial vs revenue.
Where to source liquid nitrogen (LN2)
- Industrial gas suppliers — Airgas, Linde, Praxair, Matheson. LN2 dewar rental typical $50-100/month; refills $0.30-1.00/liter.
- Hospital pharmacy — if you're affiliated with a hospital, their central supply can often provide LN2 at internal transfer pricing.
- University research supply — if you're near a university medical/research complex, their supply chain has LN2 available.
- Vet supply — some vet supply distributors (Patterson, Henry Schein Vet) carry LN2 for reproductive medicine (semen storage) — often same-day pickup available for small clinics.

The core cryotherapy mechanism is identical across all commercial dermatology cryoguns — an insulated LN2 reservoir + trigger spray + interchangeable freeze tips. What you're paying for at Brymill/Wallach pricing is 40-year brand history and distributor markup. What you're paying for here is the same tool minus the distribution middleman.
Cleaning + Maintenance
- Between patients: wipe freeze head with alcohol pad; disposable single-use tip covers available for shared clinic use
- Daily: wipe exterior with clinical disinfectant per your facility's SOP
- Weekly: empty residual LN2, allow reservoir to warm, inspect O-ring seal
- Monthly: replace freeze head O-rings (kit sold separately, ~$25)
- Storage: when not in use, keep the reservoir empty and cap sealed; store upright

Frequently asked questions
Is this the same as a Brymill or Wallach cryogun?
Same technical class (portable LN2 cryotherapy device) with equivalent core mechanism. Brymill has more brand history and their Cry-Ac Tracker has an electronic timer/temperature display which this unit doesn't have. If you need timer/telemetry, buy Brymill. If you need a functional 350ml LN2 sprayer with 6 interchangeable freeze heads for standard outpatient dermatology cryotherapy, this delivers that at less than half the price.
Do you sell replacement freeze heads separately?
Yes. Individual freeze heads and O-ring replacement kits available. Email sales@scimedstore.com for pricing. Typical replacement head: $18–35 depending on size.
What CPT codes does this device support?
Standard dermatology cryotherapy codes: 17110 (up to 14 lesions), 17111 (15+ lesions), 17000/17003/17004 (actinic keratosis destruction — first lesion, 2–14, 15+). Reimbursement varies by payer and geography — generally $80–150 per session net.
How is this shipped — do you ship the LN2 too?
The cryogun ships empty and dry via UPS/FedEx. LN2 is NOT included and must be sourced locally (see LN2 sourcing section above). Cryogun ships same-day US on orders before 2 PM PT.
What's the warranty?
90-day defect warranty from ship date — if the unit fails due to manufacturing defect within 90 days, we replace or refund. Replacement freeze heads and O-rings available for 24 months.
Do I need a prescription or medical license to buy this?
This is a general controls Class I FDA-registered medical device — no prescription required for practitioner purchase. We do verify that buyers are practitioners, clinics, or medical institutions. Consumer purchases are declined.
Can I use this for pediatric cryotherapy?
Yes — molluscum contagiosum treatment in pediatric patients is a common indication. Use the smallest freeze head + shortest freeze duration + parent/guardian holding the child.
Do you offer training on cryotherapy technique?
No — this is a device sale. Cryotherapy training is your responsibility (dermatology residency, CME courses, AAD guidelines). We include the IFU with basic operation instructions but not clinical technique training.
Is this available for international purchase?
Yes. International orders ship via DHL Express. For clinic procurement to GCC, MENA, UK, EU, AU/NZ, we offer DDP terms via clinic@scimedstore.com.
What if it arrives damaged or doesn't work?
Report within 48 hours of delivery — replacement or full refund. Photos of damage help expedite. Contact sales@scimedstore.com.
