Filtered Micropipette Tips for our 1000µL to 5000µL pipetter! These are filtered to prevent the user from accidentally sucking liquid into the pipetter and allowing for more sterile transfers between vessels. These include a closing rack for easy storage and use! The tips and rack have been sterilized with Ethylene Oxide (EO) to allow for aseptic use in phytoplankton or bacterial culturing. These filter tips are approximately 123mm long and have graduations or markings from 1mL to 5mL in 0.5mL increments.
