Microplates, quartz
Supplier: Hellma
Microplates are increasingly being used in areas such as clinical chemistry and pharmaceutical research. Plastic microplates however are not suitable for all purposes. If chemical resistance, UV transmission, microscopic observation or thermal stability are required, it is better to use quartz microplates. These can be provided to the same basic dimensions as the plastic plates.
