Griffin beakers in polymethylpentene (PMP), polypropylene (PP) and ethylene tetrafluoroethylene (ETFE). Choose PMP for glass-like clarity, ETFE for extreme chemical resistance and PP for general purpose use. Beakers are screened with approximate volumes.

PMP (polymethylpentene) provides glass-like clarity. Cleaning at no higher than 60°C is recommended to preserve markings on products with colored overprinting.
