PALL 4523 Acrodisc Syringe Filters with Glass Fiber - 1 µm, 25mm (nominal), 200/pk

The Pall 4523 is designed for prefiltration and sample clarification, removing particulate matter before analysis. It is especially useful for protecting HPLC, UV/VIS, and other analytical instruments from clogging and contamination.

A 1 µm glass fiber filter is ideal for handling samples with heavy particulate loads, as it allows higher flow rates and reduces clogging. It is often used as a first filtration step before finer membranes (0.45 µm or 0.2 µm) to improve overall efficiency.

The filter uses binder-free borosilicate glass fiber, offering high loading capacity, low extractables, and fast flow rates. This makes it particularly effective for difficult or viscous samples that would clog standard membrane filters.

This model features a 25 mm diameter, 1 µm nominal pore size, and approximately 3.9 cm² filtration area. It includes a chemically resistant polypropylene housing, operates up to about 82°C, and is supplied in packs of 50 (200 per case).

Yes, the Pall 4523 can be used as a standalone prefilter or in series with a finer membrane filter. Using it upstream helps extend the life of final filters and analytical columns, reducing downtime and replacement costs.
