Complete filter/storage system includes a
polystyrene (PS) filter
funnel joined by a color-coded
polyethylene adapter to
a removable PS storage
bottle. The adjustable,
angled hose connector simplifies vacuum-line attachment and ensures stability. Membrane
material and pore size
are printed on every unit
for easy identification.
Glass fiber prefilters are
included.
Polystyrene funnel with polyethylene neck
adapter for use with wide-mouth (45 mm)
polystyrene or glass storage bottles. Colorcoded and printed with the membrane
type and pore size for easy identification.
Includes glass fiber prefilter.

Disposable Vacuum-Driven Filter Devices
For vacuum filtering solutions in 50-mL centrifuge tubes
Filter devices feature high-quality membranes. Express® (PES) membranes
are ideal for low protein binding and exhibit faster flow rates with viscous solutions. Durapore®
PVDF membranes offer the lowest protein binding available and are ideal for scale-up applications. Nylon mesh membranes are best for large particle removal.
To filter, attach the unit directly to the 50-mL centrifuge tube containing your sample, flip it, and apply a vacuum. The filtrate collects directly in the attached 50-mL tube eliminating sample transfers between tubes. Disposable devices are sterile and have a 50-mL process volume.
