Whatman Membranes for Microbiological Control
These membranes are used to quantitatively
evaluate microorganisms. The liquid is filtered
through a membrane and microorganisms
collected on the membrane surface. The filter
is incubated on a nutrient medium and the
individual colonies can then be evaluated.
GE Healthcare, through the Whatman portfolio, is recognized
throughout the world for their expertise in the area of separations
technology and the range of unique and innovative products that
this technology makes available.

Whatman® VACU-GUARD® Inline Filter Devices
The easy-to-use VACU-GUARD inline filter devices help to confine
and isolate infectious materials in vacuum systems and protect your
laboratory.
Cat. No.
The GD/X filter contains a unique prefiltration
stack of 100% borosilicate glass. The prefilter will
retain fine particles down to 0.7 μm, allowing
difficult sample filtration with less hand force.
The volume of the sample filtered is 3-7 times
greater than a single-layer membrane. PP
housing. Syringe filters can be autoclaved.
Available as 13 and 25 mm diameter.

Whatman QM-A Quartz Filters
®
High-purity quartz (SiO2) microfiber filters are used for air sampling
particularly at high temperatures and in PM-10 testing. Because of
the low level of alkaline earth metals, ‘artifact’ products of sulfates and
nitrates (from SO2 and NO2) are virtually eliminated.
