Radionuclides and Corrosion Products are captured by these novel ion exchange filter papers, allowing plant personnel to track system and plant performance. Individual, highly functionalized, strongly basic anion and strongly acidic cation exchange papers are produced by a unique patented technology.

This technology achieves very fast ion exchange kinetics and provides the highest available ion exchange capacity per disk. The high performance papers fit all standard 47mm diameter filter holders and are durable, easy to handle, and simple to use.


  • Anion exchange filter disks in the chloride form – convert to desired ionic form (i.e. hydroxide) as required
  • Strongly basic, quaternary ammonium functionality
  • Measure iodide and other anionic radionuclides and anions
  • Fifty, 47mm diameter disks per box – 10 disks per sealed polyethylene bag


  • Cation exchange filter disks in the hydrogen form
  • Strongly acidic, sulfonic acid functionality
  • Measure corrosion products and other cations and cationic radionuclides
  • One hundred, 47mm disks per box – 10 disks per sealed polyethylene bag



  • High performance, specialty hydrophilic paper for a variety of analytical requirements
  • Uniform resin distribution throughout each disk
  • Standard 47mm diameter
  • Highly functionalized, highest ion exchange capacity analytical filter disks available
  • Filter disks are easily digested by standard analytical methods 


  • Excellent hydraulic characteristics
  • Consistent ion exchange capacity and utilization
  • Fit standard bench-top and inline filter holders and housings
  • Single disk used per test
  • Simple to quantify ions removed

Germ Africa

The company traces its roots back to Germ Oils of the UK, and commenced business in South Africa in 1905. The company was incorporated in South Africa as a public company in 1938, with the parent company, Germ Oils of the UK, as its major shareholder. In the late 1960’s the company in South Africa was sold to the local management following a take-over of the parent company in the UK.

Today, Germ Africa (Pty) Ltd manufactures and trades in sectors mainly incorporating

  • Filtration
  • Metering/Dosing Pumps
  • Ion Exchange Resins
  • Industrial Lubricants
