• Resumen

  • Semimicro pressure filtration is carried out by pressurizing a suspension through pushing the piston of a gas-filled plastic syringe whose needle perforates the closure of a cylindrical filter funnel. Basic features as well as pros and cons of vacuum and pressure filtration are pointed out and compared to support rational choice between the two procedures.
