Diagnostics

Hahnemühle filter papers are ideal for the production of highly sensitive allergy-tests, test-kits for the isolation of DNA/RNA, and the blotting after gel-electrophoresis.

 

Target User:

Service labs for medical diagnostics and manufacturers of testkits, needing highest purity of the carriers and filter medium.

 

Typical festures of the filter papers:

  • The Hahnemühle absorbent media guarantee both, high and consistent performance.
  • Purest available raw materials are used to produce this media and assure to get no cross contamination with the chemicals in the final test device.
  • The high consistency of the paper quality level assures reliable results of the final test  device from one lot to the other over many years.
