Agilent Filtermate 0.45 micron PTFE, 100/pk 190048100

Agilent FilterMate 0.45 micron PTFE (part number 190048100) is a pack of 100 PTFE membrane digestion-tube filters designed for in‑situ filtration of liquid samples. The membrane assembly is pushed through the sample with a detachable plunger and left in the bottom of a 50 mL digestion tube (for use with p/n 190047900) so the same tube can be capped or sampled directly. It is intended to remove particulates and suspended solids from digests prior to analysis, particularly for atomic spectroscopy techniques.

Key Features:

• Part number: 190048100
• Membrane material: PTFE (polytetrafluoroethylene)
• Pore size: 0.45 micron (0.45 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

Advantages:

• Enables in‑situ filtration inside the digestion tube, eliminating a separate transfer step and reducing contamination risk.
• 0.45 µm PTFE membrane removes particulates and suspended solids that can block nebulizers or injectors, supporting reliable instrument performance.
• Leaves the filter assembly in the tube so samples can be capped or sampled directly, simplifying workflow for autosampler use.
• Packaged in laboratory quantities (100/pk) to support routine sample-prep in high-throughput atomic spectroscopy or environmental testing workflows.
