Agilent Filtermate 2 micron PTFE, 100/pk 190048000

The Agilent FilterMate (catalog number 190048000) is a PTFE-faced polypropylene in-situ filter with a 2 µm pore size supplied in packs of 100, intended for sample cleanup prior to atomic spectroscopy analysis. The filter is pushed through digests in 50 mL digestion tubes (for use with Agilent p/n 190047900); the detachable plunger is removed and the filter remains in place so the same tube can be sampled above the filter, eliminating transfers. Manufacturer and authorized distributor descriptions state it removes particulates and suspended solids (e.g., wastewater, sludge, soil digests) to prevent nebulizer or injector blockage and to improve analytical accuracy and instrument stability.

Key Features:

• Manufacturer part number: 190048000.
• Membrane: PTFE-faced polypropylene; pore size 2 µm.
• Pack quantity: 100 filters per pack.
• Designed for use with 50 mL digestion tubes (Agilent p/n 190047900).
• Intended application: pre-analysis filtration for atomic spectroscopy (AA/ICP sample digests).

Advantages:

• Efficient removal of particulates and suspended solids helps prevent nebulizer or injector blockages during atomic spectroscopy.
• In-situ filtration lets the filter remain in the digestion tube so sampling can occur above the filter, reducing sample transfers and contamination risk.
• Improves analytical accuracy, instrument performance, and long-term stability by reducing particulate carryover and downtime.
• PTFE-faced membrane offers chemical resistance appropriate for digested samples.
