Materials: PlasticBiological PropertiesThe following plastics are generally non-toxic to cell cultures:PS, PC, PE-LD, PE-HD, PP, PMP, PTFE, FEP, PFA.Technical InformationChemical PropertiesWith regard to chemical resistance, plastics are classified as follows:+o–Excellent chemical resistanceContinuous exposure to the substancedoes not cause damage within 30 days.The plastic may remain resistant foryears.Good to limited chemical resistanceContinuous exposure to the substancecauses minor damage, some of which isreversible, within 7-30 days (e.g., swelling,softening, decrease of mechanicalstrength, discoloration).Poor chemical resistanceNot suitable for continuous exposureto the substance. Immediate(!)damage may occur (lossof mechanical strength, deformation,discoloration, cracking,dissolution).Abbreviations of the described plastics (to DIN 7728)PSSANPMMAPCPVCPOMPE-LDPE-HDPPPMPETFEPTFEFEPPFAPUR:FKMEPDMNRSIPolystyreneStyrene-acrylonitrile copolymerPolymethyl methacrylatePolycarbonatePolyvinyl chloridePolyoxymethyleneLow-density polyethyleneHigh-density polyethylenePolypropylenePolymethylpenteneEthylene-tetrafluoroethylene copolymerPolytetrafluoroethylenePerfluoroethylene-propylene copolymerPerfluoroalkoxy copolymerPolyurethaneFluoro elastomerEthylene-propylene-diene-rubberNatural rubberSilicone rubberwww.brand.de337
