Abstract
Official abstract text for this publication.
Provided is a pipette tip having a visual indicator capable of confirming depth of liquid in contact with the pipette tip during a suction work. In the pipette tip, a marker-is formed on an outer surface of the pipette tip in a circumference direction in a tip end area in a tip end side for confirming the depth of liquid in contact with the pipette tip. Thereby, the depth of liquid in contact with the pipette tip is confirmed based on the marker directly or relatively.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pipette tip with a tubular shape, comprising: an opening portion at its tip end for making sucked liquid pass; an opening portion at its base end to be fitted to a pipette, and at least one marker for confirming depth of the liquid in contact with the pipette tip, the depth being determined by comparing the position of the marker with a liquid surface at the tip end of the pipette tip during a suction operation, the marker being formed on an outer surface of the pipette tip in a circumference direction exclusively on a distal tip end area of the pipette tip, and wherein circumferential outer edges of the marker along an axial direction of the pipette tip are substantially parallel to the to the outer surface of pipette tip. 2. The pipette tip according to the claim 1 , wherein the marker is integrally resin molded with the pipette tip. 3. The pipette tip according to the claim 1 , wherein the marker is integrally molded with the pipette tip made of a resin by a single molding operation. 4. The pipette tip according to the claim 1 , wherein the marker has a shape capable of molding with the pipette tip made of a resin by a single molding operation. 5. The pipette tip according to claim 1 , wherein at least one marker forms a pattern in a circumference direction and a plurality of patterns are formed in an axial direction.
