PIPETTE TIP HAVING HYDROPHOBIC SURFACE TEXTURE

PROBLEM TO BE SOLVED: To improve a process in which hydrophobic texture is added to an apical surface of a pipette.SOLUTION: A pipette tip 10 in which a first axial longitudinal direction end area 16 of the tip 10 as a longitudinal end area 16, which extends along a longitudinal axis L of the tip 10, includes a pipette opening 12, a fluid can flow through the pipette opening 12 during operation, and a second axial longitudinal end area 18 of the tip 10 as a coupling longitudinal end area 18 facing the longitudinal end area 16 in an axial direction is coupled to a coupling reverse shape of a pipette device. The pipette tip includes an outer side hydrophobic area 32 on an outside 30 of the tip 10 and an inner side hydrophobic area 26 on an inner side 28 of the tip 10 which have a secondary roughness of 100 nm to 1000 nm and a peak roughness of 800 nm to 5500 nm, and an axial extension range of the outer side hydrophobic area 32 and an axial extension range of the inner side hydrophobic area 26 are different from each other.SELECTED DRAWING: Figure 1 【課題】ピペット先端面に疎水性テクスチャを付ける工程の改善。【解決手段】ピペット先端部１０であって、先端部１０の長手方向軸Ｌに沿って延在し、長手方向端部領域１６としての先端部１０の第１の軸長手方向端部領域１６がピペット開口部１２を含み、ピペット開口部１２を通って流体が操作中に流れることができ、長手方向端部領域１６に軸方向に対向する結合長手方向端部領域１８としての先端部１０の第２の軸長手方向端部領域１８が、ピペット装置の結合反対形状に結合し、１００ｎｍ〜１０００ｎｍの２次粗さ、８００ｎｍ〜５５００ｎｍのピークピーク粗さを有する先端部１０の外側３０上の外側疎水性領域３２及び先端部１０の内側２８上の内側疎水性領域２６を含み、外側疎水性領域３２の軸方向の延長範囲と内側疎水性領域２６の軸方向の延長範囲が互いに異なる方法。【選択図】図１
