The tubular body comprises a bottom opening defined at a bottom end of the tubular body and a top opening defined at a top end and configured to clamp onto an attachment of a pipetting device. A seat region is positioned proximate the top opening on the inner circumference and configured to engage an attachment of a pipetting device. At least one groove is defined on the outer circumference. The tubular body is configured to plastically expanded in a radial direction within the at least one groove upon mounting the seat region on the attachment. The attachment comprises a larger diameter than at least part of the seat region to form an interference fit between the attachment and the at least part of the seat region when the pipette tip is clamped onto the attachment.
