Last Drop Filter/Sparger

  • Parallel filtering and sparging
  • Biocompatible PTFE frits or SS frits
  • Three different porosities

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 PTFE filter element. Connect the solvent line to the stepped "tripod" connector, which accomodates 1.5, 2.2, and 3.5 mm ID tubing. A 1/4"-28 fitting connector connects a 1/8" helium line connects to the 10 µm sparger. Both connectors are PEEK.

We recommend our 1/8" No-Ox tubing to prevent "regassing" of helium degassed solvents.
