Fison Vacuum Aspirator removes liquid by handheld aspiration at a maximum aspiration speed of 1.6 L/min and collects it in a 2 L aspirator bottle. As a vacuum aspirator for cell culture, it draws liquid off from a vessel under negative pressure, and the handheld aspiration method gives direct control over where the liquid is taken from. The vacuum system runs continuously with low noise and vibration, while the aspirator bottle holds the collected liquid until it is emptied.
