Microporous Pressure Equalization Film

Microporous Film is a gas permeable polypropylene film used in conjunction with the Series 1500 XRF Sample Cups to establish and maintain an equalization of pressure within the sample cup and sample chamber. The primary reason for maintaining an equalization of pressure is to ensure that the thin-film sample support substance will not concavely or convexly distorts thereby altering the distance from the excitation source and sample, defined by the thin-film.
