Brymill cryosurgery equipment is the clinical standard for liquid nitrogen dermatology procedures in Australian general practice, dermatology, and skin cancer clinics. Docstock stocks the full Brymill Cry-Ac range — flasks, probes, spray tips, chambers, and accessories — with all units backed by 3-year manufacturer warranty and shipped Australia-wide.
Brymill has manufactured cryosurgery equipment in the USA since 1966 and is used by more than 85% of US dermatologists.
The Brymill Cry-Ac range
Brymill's Cry-Ac flasks are the core of the range — hand-held liquid nitrogen delivery systems used for cryotherapy of skin lesions, warts, and dermatological conditions. The two flagship flask models are the Cry-Ac and the Cry-Ac 3, differing in capacity and application. Around each flask sits a supporting ecosystem of interchangeable probes, spray tips, chambers, and safety accessories.
The Cry-Ac 500ml is the workhorse of the range the standard flask most Australian dermatology and skin cancer clinics choose. Holds 500ml of liquid nitrogen, sufficient for a full clinical session, with a light-weight design that's comfortable for extended use.
The Cry-Ac 3 300ml is a smaller flask ideal for practices with lower cryotherapy throughput or where flask weight is a factor. Same interchangeable tips and accessories as the standard Cry-Ac; smaller nitrogen capacity for shorter sessions or lower patient volumes.
Both flasks work with the full range of Brymill accessories: spray tips in multiple bore sizes for varying lesion coverage, closed-probe chambers for controlled contact treatment, cryo-cone attachments for concentrated delivery, and protective cases and stands for safe storage between uses.
Comparison: Brymill flask range
| Model | Best for | Capacity | Session length | Accessories |
|---|---|---|---|---|
| Cry-Ac 500ml | Dermatology clinics, skin cancer practices, higher-volume GP clinics | 500ml liquid nitrogen | Full clinical session | Full Cry-Ac accessory range |
| Cry-Ac 3 300ml | General practice, lower-volume cryotherapy use | 300ml liquid nitrogen | Shorter sessions or lower patient volume | Full Cry-Ac accessory range |
Choosing the right accessories
The accessory choice depends on the procedures you perform. Spray tips (A, B, C, D bore sizes) are used for open-spray cryotherapy of lesions, warts, and superficial skin conditions — smaller bores for precision, larger bores for broader coverage. Closed probes and chambers are used for direct-contact treatment where controlled tissue contact matters. Cryo-cones concentrate the spray into a specific area, useful for lesions near sensitive structures like the eyes. Ear specs and otoscope tips exist for specific anatomical applications.
Frequently asked questions
How long does liquid nitrogen last in a Brymill Cry-Ac flask?
A fully charged Brymill Cry-Ac 500ml flask holds liquid nitrogen for approximately 24-36 hours before evaporation becomes significant, depending on ambient temperature and how often the flask is opened. The Cry-Ac 3 300ml holds nitrogen for a similar duration proportionally. For clinical practice, most clinics refill their flasks the same morning as procedures.
Are Brymill Cry-Ac flasks TGA-registered for use in Australia?
Brymill Cry-Ac flasks are TGA-compliant Class I medical devices supplied to Australian standards. Documentation is available on request.
What's the difference between the Cry-Ac and Cry-Ac 3?
The Cry-Ac (500ml) and Cry-Ac 3 (300ml) are functionally identical — both use the same interchangeable spray tips, probes, chambers, and accessories. The only difference is nitrogen capacity. Higher-volume practices choose the 500ml for longer sessions between refills; lower-volume practices choose the 300ml for lighter weight and lower nitrogen consumption.
Which spray tips should I order with my Cry-Ac?
Most clinics start with the A and B bore tips as their working set — the A bore for precise, small-lesion treatment (verrucae, small solar keratoses), the B bore for larger lesions or when broader coverage matters. C and D bores are used less frequently for very large lesions or field treatment. If you're new to cryotherapy, the standard tip set (A + B) covers most general practice needs.
Do I need any special storage or safety equipment?
Yes. Liquid nitrogen requires appropriate handling — cryo-safe gloves, safety glasses, and adequate ventilation in the treatment area. Brymill supplies protective cases and stands for the flasks themselves. Docstock stocks the full range of Brymill safety accessories alongside the flasks and treatment tips.
What warranty do Brymill Cry-Ac flasks come with?
Brymill provides a 3-year manufacturer warranty on all Cry-Ac flasks — one of the longest warranties in the cryosurgery equipment category. Docstock handles all warranty claims directly on behalf of customers, and Brymill's reputation for reliability means warranty claims are rare.
Do you ship Brymill cryosurgery equipment Australia-wide?
Yes, Docstock ships Australia-wide with tracked delivery on all Brymill equipment. Standard delivery is 2-5 business days for metro areas, 5-10 business days for regional and remote locations. Cry-Ac flasks are shipped empty — liquid nitrogen is not shipped with the equipment and must be sourced locally.
