BASE RETAINER SCREW  FOR ADJUSTABLE OVATION PIPETTE

Base screw with 'O' ring for Ovation adjustable, fixed volume, multichannel and macro volume pipettes

Liquid-blocking Nozzles, Filters and Nozzle Seals

The replacement nozzle contains an internal aerosol/liquid barrier filter to prevent liquid from being aspirated into the pipette. If this filter becomes wet, the pipette will not aspirate fluid until a new filter or replacement nozzle is installed. A variety of options to accomplish this are available.
