Overview [Tab]
The Last Drop filter/sparger combines filtration and sparging in a single unit. A flat filter element sits parallel to the bottom of the reservoir, ensuring all but the last 2% of mobile phase is filtered without drawing air into the system.
The PTFE housing contains a mobile phase filter with stainless steel, PTFE, or hydrophobic PE filter element. The filter/sparger features a PEEK tripod connector which slips into 1.5 mm, 2.2 mm, or 3.5 mm ID solvent lines, and a nut and ferrule for the sparging line. The spargers have a porosity of 10 microns.

TECH TIP
We recommend using metal-free PTFE filters for sensitive biochromatography applications where metal surfaces may corrode or interact with samples.
