EM-Tec filter disc holders are developed to hold flat discs type filters to enable SEM / EDS analysis. EM-Tec filter disc holders comprise of two parts; a flat base plate to hold the filter disc and a cap which acts as clamping ring to keep the filter flat on the base. The cap is secured with three screws at the side of the base plate. The base plate and clamping ring are made from vacuum aluminium; the screws are made form stainless steel. The EM-Tec filter disc holders are available for 13, 25, 35, 47 and 90mm filter discs. Custom diameters can be made on request.
