Strength for environmental analysis
Grade GF 9 borosilicate glass filters can be used in a range of environmental analysis applications. The added strength of the inorganic binder makes these filters appropriate for use in retention of samples with heavy particles. Other applications include:

• Determination of PCB*, DDE, DDT, furans, and dioxins in air
• Pollution measurements in industrial, urban, and populated areas
• Dust measurements in the workplace
• Determination of dust fraction in technical gases
• Testing the effectiveness of dust-collecting
