EM-Tec top reference holders for metallographic mounts

The EM-Tec top reference holders ensure the same focus conditions for the SEM and same take-off angle for the X-ray analysis system the for all mounts in the holder. They have been designed for SEM/EDS/WDS analysis on multiple metallographic and petrographic mounts. The mounts are placed against three reference lips and secured with screws from the side. The reference lips are only 1mm thick and beveled to reduce X-ray analysis interference. It is intended for the larger analytical SEMs with a large SEM stage. Made from vacuum grade aluminium with stainless steel screws. One of the positions can be used to hold a calibration standard with pure elements and/or known compounds. 
There are three top reference holders for metallographic or petrographic mounts of different sizes:

EM-Tec R6 top reference holder for six of the Ø25mm or 1” (Ø25.4mm) mounts
Consists of a top part only with a thickness of 15mm. With the supplied height extender (10mm high), up to 24mm high samples can be mounted. The mounts are secured from the side by screws.

EM-Tec R4 top reference holder for four of the Ø30mm or 1-1/4” (Ø32mm) mounts
Optional adapter sleeves for Ø 25mm or 1” mounts are available for this holder. The EM-Tec R4 top reference holder consist of two parts: top with reference lips and base with screws to push the mounts. The maximum sample height is 20mm. The mounts are secured with screws and can be pushed up with screws in the base. If reduced height metallographic mounts or thin samples are used, Ø25mm spacer discs can be used to ensure that the mounts are pushed against the reference lips. Pushing from the base allows for small angle adjustment if the polished surfaces of mounts are not perfectly perpendicular to the sides. The EM-Tec R4 holder can also be used without the base on the EM-Tec stage adapters with an M4 screw.

Top reference holders EM-Tec R2 for two of the Ø40mm and EM-Tec R2-1.5 for two of the Ø 1-1/2” (Ø38mm) mounts
The EM-Tec R2 and R2-1.5 top reference holders consist of two parts: top and base. The maximum sample height is 20mm. The mounts are secured with screws and can be pushed up with screws in the base. If reduced height metallographic mounts or thin samples are used, Ø32mm spacer discs can be used to ensure that the mounts are pushed against the reference lips. Pushing from the base allows for small angle adjustment if the polished surfaces of mounts are not perfectly perpendicular to the sides. The EM-Tec R2 and R2-1.5 top reference holders include two positions for calibration standards mounted on a standard 12.7mm pin stub. The top of the EM-Tec R2 and R2-1.5 holders can also be used without the base on the EM-Tec stage adapters with an M4 screw.

Top reference holders EM-Tec R22 for four of the Ø40mm and EM-Tec R22-1.5 for four of the Ø 1-1/2” (Ø38mm) mounts 
The EM-Tec R22 and R22-1.5 have the same design as the EM-Tec R2 or R2-1.5 top reference holders, but double the capacity: 4 x  Ø40mm or 4 x 1-1/2” metallographic mounts. The EM-Tec R22 and R22-1.5 top reference holders includes four positions for calibration standards mounted on a standard 12.7mm pin stub.

EM-Tec R5 top reference holder for two of the Ø50mm or 2”  mounts
The EM-Tec R5 top reference holder consist of two parts: top and base. The maximum sample height is 26mm. The mounts are secured with screws and can be pushed up with screws in the base. If reduced height metallographic mounts or thin samples are used, Ø32mm spacer discs can be used to ensure that the mounts are pushed against the reference lips. Pushing from the base allows for small angle adjustment if the polished surfaces of mounts are not perfectly perpendicular to the sides. The EM-Tec R5 top reference holder includes two positions for calibration standards mounted on a standard 12.7mm pin stub. The EM-Tec R5 holder can also be used without the base on the EM-Tec stage adapters with an M4 screw.

EM-Tec R7 top reference holder for one 49 x 89mm block mount
The EM-Tec R7 top reference holder consist of two parts: top and base. The maximum sample height is 26mm. The mounts are secured with screws and can be pushed up with screws in the base. Pushing from the base allows for small angle adjustment if the polished surfaces of mounts are not perfectly perpendicular to the sides.
