Whatman Grade GF 8 Glass Microfiber Filters with Binder

Description

Nominal particle retention of 3 µm
Air flow rate of 12 s/100 ml/1.56 cm²
Inorganic binder for increased strength and temperature resistant up to 500°C
Fast filtration speed
Can be used as a pre-filter for dense samples
Function as air pollution filters for detecting furans, PCB, and other chemicals

Environmental pollution analyses often require binder-strengthened glass filters to support heavy samples.

Air pollution filters for furans and other pollutants

With the added strength of an inorganic binder, grade GF 8 glass microfiber filters serve as air pollution filters by retaining a range of heavy particles found in vapor samples. Other applications include:

Air pollution filters for PCB*, DDE, DDT, furans, and dioxin retention for analysis
Pollution measurements in industrial, urban, and populated areas
Workplace dust measurements
Measurement of dust fraction in technical gases
Dust-collecting effectiveness testing

* PCB = polychlorinated biphenyl, DDE = dichlorodiphenyldichloroethylene, DDT = dichlorodiphenyltrichloroethane

Parameter	Grade GF 8 Coarse Particle Filter with Binder, circle & sheet
