What is the purpose of the liquid blocking nozzle?

The liquid blocking nozzle contains an internal aerosol/liquid barrier filter to prevent liquid from being aspirated into the pipette. It also offers some protection to internal parts from routine exposure to hazardous liquids and vapors. If this filter becomes wet, the pipette will not aspirate fluid until a new nozzle is installed.
