These Premier Lab Supply 89 mm (3.5 in) circles of 3.0 µm (0.12 mil) Mylar® film are cut and ready to use as the window film in XRF sample cups. A thin film lets X-rays pass to and from the sample with little loss, which matters most when you are measuring light elements. Each box holds 500 circles, so there is no cutting from a roll.
