Systems and methods for nesting filtered pipette tips to reduce storage space and plastic waste

A method for nesting refill filtered pipette tips to reduce storage space and plastic waste, the method comprising:

• loading a lower filtered refill wafer comprising a lower plurality of refill filtered pipette tips into a nested filtered pipette tip rack so that the lower plurality of refill filtered pipette tips are easily loadable onto a pipette, the lower filtered refill wafer comprising the lower plurality of refill filtered pipette tips having holes between top portions of the lower plurality of refill filtered pipette tips;
• aligning an upper filtered refill wafer comprising an upper plurality of refill filtered pipette tips in a same configuration as the lower filtered refill wafer comprising the lower plurality of refill filtered pipette tips;
• rotating the upper filtered refill wafer comprising the upper plurality of refill filtered pipette tips one-hundred-and-eighty-degrees (180°) relative to the upper filtered refill wafer after the aligning of the upper filtered refill wafer and before loading the upper filtered refill wafer comprising the upper plurality of refill filtered pipette tips into the nested filtered pipette tip rack;
• and
• nesting the upper filtered refill wafer comprising the upper plurality of refill filtered pipette tips into the holes between the top portions of the lower plurality of refill filtered pipette tips, the nesting of the upper filtered refill wafer resulting in bottom portions of the upper plurality of refill filtered pipette tips being nested in the holes between the top portions of the lower plurality of refill filtered pipette tips thereby reducing storage space for the nested filtered pipette tip rack compared with storage space for a filtered pipette tip rack that is not nested.
