These plates are very specialized and are prepared according to several Pharmacopeia methods.
They are used used in the analysis of mannitol/sorbitol.
Warning:
These Carbomer plates are very fragile and will most definitely arrive with silica flaked off of the plate. This has always been the case with these very custom TLC plates. They are still very usable in this condition, but do not have the best appearance. We give this warning ahead of time because these plates are not returnable.
