EM-Tec filter disc holders for SEM / EDS analysis

EM-Tec filter disc holders were 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. EM-Tec filter disc holders are available for 13, 25, 35, 47 and 90mm filter discs. Custom diameters can be made on request. The edge of the cap has a 45° angle to avoid contribution of aluminium to the EDS spectra. EM-Tec filter disc holders enable SEM / EDS analysis of particles, fibres and debris on the filters.  They are available with:

• Standard pin to fit  SEMs using a standard pin; Thermo Fisher,  ThermoFisher Scientific/FEI, Philips, Tescan, Phenom,  Cambridge Instruments, Leica and CamScan SEMs.
