Micro-quartz fibre filters
Filters Glass Fibre Filters
Micro-quartz filters are useful for testing hot "stack" gases as the quartz fibers can withstand temperatures up to 900 °C. In addition, micro-quartz is used when the highest purity media is required. With excellent filtration properties and minimal traces of metals and minerals, quartz fibers are dimensionally stable and can be used in the analysis of acidic gases with the exception of hydrofluoric acid.

  • MK 360 conditioned by high temperature pre-heating
  • Made of extremely pure micro-quartz fibers
  • Binder free
  • Particularly suitable for low amount of particles

MK 360 is used in PM 10 testing according EPA ambient air monitoring, DIN EN ISO 23210 and DIN EN 14902:2005. These filters are available sequentially numbered according to EPA standards.
