These UNIPLATES are produced using alumina manufactured by ICN Biomedicals for methods specifying Woelm alumina. They contain no calcium sulfate binder. ICN alumina UNIPLATES were previously available in three forms - neutral, basic, and acidic. Now they only still manufacture the acidic version.
Note: These plates are very fragile and are prone to chipping. They are still very effective, but due to their rare nature are NOT able to be returned.
