Sterile PES Membrane Filtration

The 0.45um PES membrane delivers sterile filtration without the need for autoclaving. Graduated markings on the 1000mL receiver allow direct volume measurement during use. The included stopper helps maintain sterility after processing is complete.

Questions about this item

How do I attach the 90 mm PES membrane filter unit to a vacuum flask without leaking?

Fit the supplied stopper firmly into the flask neck, then connect the vacuum hose to the side arm; the 90 mm diameter matches standard ground-glass joints so the seal holds at full vacuum.

When should I replace the 0.45 µm membrane during a filtration run?

Discard the sterile unit once flow slows noticeably or after filtering 1 L, because the membrane cannot be autoclaved and each unit is single-use.

What volume limit stops a continuous run with the 1 L upper reservoir?

The 1000 mL upper capacity fills first; you must empty the 1 L receiver before filtering another batch.
