Vacuum Aspirator 18303022 (CAT#: STEM-BC-1999-ZJF)

The 18303022 is a compact vacuum aspirator designed for rapid and safe aspiration of liquid waste from laboratory vessels without direct manual handling. A built-in brushless motor generates consistent vacuum for continuous or intermittent liquid removal operations. The sensitive liquid level detection system monitors the waste collection bottle and triggers an audible-visual alarm to halt suction before overflow occurs. Vacuum level is adjustable via a rotary knob, with indicator lights confirming the selected setting for different application requirements. A self-locking tube connector prevents liquid leakage or aerosol release at disconnection points. All components in contact with liquid waste are autoclavable for decontamination between experiments. The unit is easy to disassemble for cleaning and maintenance without tools. The ergonomic form factor and collection bottle handle allow stable bench-top placement or carry in the working area. This aspirator is suitable for cell culture media removal, wash step aspiration, ELISA plate processing, and microbiological containment applications. It is widely used in cell biology, microbiology, and analytical laboratory settings.
