My patients and family appear to be overwhelmed with intractable warts.
In consequnce I wish to get readily available liquid nitrogen at the
surgery.
So far I have a quote for a Dewar costing circa £800 and delivery at £200
pa. Anybody recommend a cheaper option (but preferably not involving
personal collection for a dedicated clinic - I would prefer to have the
stuff handy all the time)
