The invention relates to the use of blends of biodegradable polymers made from renewable resources for the production of carrier systems for analytical tests. Blends of biodegradable polymers such as PHB (polyhydroxy butyrate) or PLA (polylactide) were found suitable for systems. They are available commercially. The formulations have affinities to organic molecules similar to that of the currently used polystyrene, and can be transformed as the latter on plastic injection moulding and processing machines into the same type of carriers for chemical, physical, enzymatic or immunological test systems. Application of PHB and PLA formulations according to the invention provides important advantages over using polystyrene as matrix substance: after use, the carriers can be composted or enzymatically degraded without the need of expensive disposal in landfill sites. In addition they are made from renewable resources and do not increase the carbon dioxide content of the atmosphere, even when burned.
