Last Drop Filter/Sparger - Low Pressure

Last Drop Filter/Sparger

 

 

 

The Last Drop filter/sparger combines filtration and sparging in a single unit. The PTFE housing contains a mobile phase filter with either a stainless steel or a PTFE 2.5 micron filter element.

 

The filter/sparger features a PEEK tripod connector which slips into 1.5, 2.2, or 3.5 mm ID solvent lines, and a nut and ferrule for the sparging line.

Last Drop Filter/Sparger

Spargers have a porosity of 10 microns.
