Pipette tip family comprising pipette tips for use with pipettes of a pipette family and pipette family comprising pipettes for use with pipette tips of a pipette tip family

A pipette tip family comprising:

• a plurality of different pipette subfamilies;
• a plurality of pipette tips configured to be used with different pipettes of a pipette family, wherein each of the pipettes comprise a spigot, wherein each of the plurality of pipette tips comprises,
• a tip cylinder comprising,
• a hollow body including a bottom end and a top end, wherein the bottom end defines a tip opening and the top end defines a mounting opening,
• a seating region configured to clamp to the spigot, and
• a cylindrical plunger travel path defined between the tip opening and the seating region, a tip plunger comprising,
• a plunger sealingly guided in the plunger travel path, and
• a plunger rod comprising a top end and projecting upward, wherein the plunger rod is configured to clamp to one of the pipettes,
• wherein at least two of the plurality of pipette tips are grouped into each of the plurality of different pipette subfamilies,
• wherein each of the pipette tips in a same pipette subfamily has the top end of the plunger rod arranged at a same position relative to the seating region while the tip plunger is in the respective lowest position;
• and
• wherein the pipette tips of different pipette subfamilies have the top ends of the plunger rods arranged at different positions relative to the seating region while the tip plungers are in the respective lowest positions,
• wherein in the respective lowest position, the tip plunger rests against the tip cylinder and is inhibited from being pushed deeper into the tip cylinder, and wherein the plurality of pipette tips of each pipette subfamily are configured to be used for pipetting with pipettes of a pipette type matched thereto and are not configured to be used with pipettes of a pipette type not matched thereto,
• wherein the seating region of the plurality of pipette tips comprises a circumferential bead on an inner circumference of the tip cylinder,
• wherein the plurality of pipette tips comprise at least one pipette tip of at least a first pipette tip type of a first pipette subfamily, wherein when the tip plunger is in the respective lowest position, the top end of the plunger rod is positioned in a first position above the circumferential bead on the inner circumference of the tip cylinder for use with pipettes matched to a first pipette type, wherein the plurality of pipette tips comprise at least one pipette tip of at least a second tip type of a second pipette subfamily, wherein when in the respective lowest position of the tip plunger, the top end of the plunger rod is positioned in a second position below the circumferential bead arranged on the inner circumference of the tip cylinder for use with pipettes matched to a second pipette type, wherein the plurality of pipette tips comprise at least one pipette tip of a third tip type of a third pipette subfamily, wherein when the tip plunger is in a the respective lowest position of the tip plunger, the top end of the plunger rod is arranged in a third position between the first and second positions for use with pipettes matched to a third pipette type.
