Aspirators use a vacuum power to aseptically dispose of supernatant fluids from a variety of laboratory vessels. Working well with tissue and cell culture media, biological immunology reagents, or any liquid chemical waste, the systems are exceptionally versatile. An autoclavable hydrophobic bio-filter protects the vacuum supply and laboratory environment from biohazardous aerosols in some models. Available in handheld and portable sizes for easy access and use, the vacuum aspiration systems create a stable vacuum for reliable results.
