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.

The upper part of the microplate is attached directly to the synthetic quartz base using the process of direct fusion. The result of this joining process, which does not use glue or sinter glass is an evenness of the well base, which is less than the wavelength of light. The join has the same high resistance against extreme temperatures and aggressive chemicals as the main body of the quartz itself. Furthermore, this guarantees that each well is completely liquid.
