MEK Rub Test Machine

Product Summary

The MEK Rub Test Machine has been developed to combat the problem of inconsistent test results between operators.

This semi automated machine gives the line operator and quality control personnel the ability to duplicate results from the laboratory to the production line every time. The front panel mounted controls make it simple for the user to program the required number strokes to run for a specified test, then simply lower the head, close the cover, and press the start button, the machine will do the rest. This frees the operator to perform other QC test while the machine performs the rub test consistently and reliably with the added benefit of greatly reducing operator contact with and exposure to the solvents being used for the rub test procedure. Once the cycle counter reaches the preset number of strokes the unit will shut off the solvent flow and return to the start position ending the test. The operator can return at any time to check the results of the Rub Test. The quick change solvent pad system means that preparing for the next test procedure is quick and efficient.

Variable Stroke Kit
This add on kit allows for the use of non standard size panels. Panels ranging in length from 85mm (3.5”) to 305mm (12”).

Variable Weight Head
The variable weight head allows you to change the mass of the head from 1000g to 3000g in 50g increments, thus allowing for testing to either the ASTM or EU standards without having to change the head block.

Dual Reservoir
The dual reservoir is an option to have two independent solvents for the rub test procedure which are loaded and are ready to be used.
