Abstract
A pipette tip container comprising a pipette tip having a lumen extending between a proximal opening of a first diameter and a distal orifice of a second smaller diameter; a pellet arranged in the lumen of the pipette tip between said proximal opening and distal orifice, the second diameter being too narrow to let the pellet pass; and a retainer arranged between the pellet and the proximal opening and arranged to prevent the pellet from moving past the retainer in the lumen but to let fluid move past the retainer in the lumen; the retainer having a distal end such that a portion of its periphery does not contact the inner wall of the lumen, a proximal end such that a portion of its periphery maintains the retainer in the lumen by friction with the inner wall of the lumen; and a radial opening between the distal and proximal ends.
