           EM-Tec VS42 universal spring-loaded vise

Description

The EM-Tec VS26 dual action spring-loaded vise clamp includes two removable push rods and four dowel pins which fit into the top of the jaws. The maximum clamping capacity between the vise jaws is 26mm. Available with either the standard 3.2mm pin or an M4 threaded hole for mounting on the SEM sample stage.

 

 

Operation

Consider wearing gloves to avoid contamination.

  • To open the EM-Tec universal spring-loaded vise clamp, pull on the side of the brass sliding bars.
  • Place the sample between the vise jaws and gently release the sliding bars.
  • The tension on the 4 springs will hold the sample between the jaws in the middle of the holder.
  • The universal spring-loaded vice clamp acts as a centering vise.

The aluminium vise plates are mounted on the brass sliding bars with brass M3 screws. The reversible vise jaws comprise a smooth side and a side with three small grooves. The grooves are more suitable for small round samples or to hold sample with a rough side.
For awkwardly shaped samples, the vise jaws can be removed and 4 dowel pins can be inserted in the brass sliding bar to clamp the sample between the 4 dowel pins.
Optional vise jaws are available for large round samples.  By using longer M3 screws, the vise jaws can be stacked to double the jaw height from 12 to 24mm.

For samples which are thinner than 1mm, an alternative vise type holder with a screw should be considered. The spring tension is weaker when the jaws are (nearly) closed. For delicate samples, consider lining the jaws with conductive soft material.
