Description
The EM-Tec RG2 and RG4 geological thin sections top reference holders are intended for analytical SEM/EDS/WDS or EPMA investigations. The petrographic or geological thin sections are pushed against a top reference edge to ensure a specific height for all loaded samples.
Operation
Consider wearing gloves to avoid contamination. The petrographic or geological slides need to be loaded from the sides between the spring and the top reference edge. To facilitate loading, the spring can be pushed down.
At the middle of the top reference edge a separation pin is situated; push the slide gently against this pin.
When the slide is loaded, check if the spring tension is sufficient to push the slide against the top reference edge.
Spring adjustment
The springs are made from spring grade phosphor bronze and can be easily adjusted. Using flat nose pliers.
The gap between the spring and the top reference edge should be less than 1mm. The tip of the spring may just rest against the top reference edge. The holders are built to facilitate 1 – 1.2mm thick glass slides.
If the spring is too tight, adjust downwards to create a slightly larger gap.
If the spring is too loose, adjust upwards to create a slightly smaller gap.
The adjustment of the spring is easier when the top reference edge and the spring are removed from the base plate. Remove the 4 socket cap screws from the top reference edge by using the provided 2mm allen key. The spring can now be adjusted. If adjustment is not satisfactory, it may be needed to remove the spring from the holder plate; remove the socket cap screw which holds the spring. After adjustment re-mount the spring and the top reference edge with the socket cap screws.
Screws for the top reference edge: M2.5 x 8mm.
Screws for the springs: M2.5 x 4mm.
