Many assays require that potential contaminants be removed from samples
prior to application. Depending on the sample type and specific
components to be removed, several different materials can be utilized.
Whatman offers a full range of proven, high-quality sample prep
technologies.
Features and Benefits
- High flow rates and capacity.
Whatman glass fibre materials provide superior performance compared
with fine pore membranes.
- Selective particulate removal.
Whatman filters enable particles of known diameters to be removed.
- Guaranteed performance.
Whatman glass fibre is the recognized gold standard for particle
filtration.
Product Range and Properties
GF/F
A binder-free glass fibre filter with high retention of small
particulates.
GF/B
A binder-free glass fibre filter with strong retention of small to
medium particulates and higher flow rate and loading capacity than GF/F.
GF/AVA
A polyvinyl alcohol-bound glass fibre filter that retains medium-sized
particulates. Offers improved strength compared to binder-free
materials.
GF/DVA
A thick, polyvinyl alcohol-bound glass fibre filter for rapid filtration
and removal of coarse particulates.
