Rubber Fab is proud to introduce a technology that enables the use of a self contained biological indicator in sanitary process lines. This unique Rubber Fab Smart Gasket® permits either top loading or inline positioning of the EZTest® self contained biological indicator and/or temperature probe.

Patent #6,927,058

Additional technical and usage information about the EZTest® biological indicator and related testing products is available at

The great advantage of a self contained biological indicator over the traditional spore strip in glassine is the time saved when confirming spore kill. Results are easily obtained in only 24 hours (versus the 5 to 7 days required with a spore strip).

You can feel secure knowing that the biological indicator will not be lost down stream in the process. The fail-safe Rubber Fab Smart Gasket® holds the indicator in place for easy retrieval. Available for 3/4'', 1.0'', 1.5'' and 2.0'' Sanitary Tri-Clamp® process lines.
