• Material: borosilicate glass 3.3, PTFE wetted parts
• Operating pressure: atmospheric to 0.5–1 bar (lab-scale)
• Membrane/frit support: glass frit, ceramic, or polymer membrane depending on design
• Housing volume: typically small (e.g. < 1 L)
• Port interfaces: standard glass joints and ports for feed/permeate/retentate
• Flow rates: low volume (mL to few L/h)
• Temperature range: ambient to ~120–150 °C (solvent dependent)
• Sealings: PTFE gaskets or compatible seals to ensure leak resistance
• Modular layout: removable filter element, easy cleaning, and interchangeability
