When performing routine laboratory liquid handling where contamination concerns are low, an RNase and DNase free pipette tip without a filter can suffice.
Non-filter pipette tips are made from the same virgin polypropylene and to the same exacting specifications, but are less expensive because they do not have the additional filter material.
RNase and DNase free pipette tips without a filter are available in individually wrapped sterile boxes as well as reload stacks.
The non-filter pipet tips in this category are all designed to be used with universal fit pipettes.
