Micro-titration vessel

A titration vessel comprising:

• a top portion, the top portion having an opening and an interior wall defining a top cavity having a first diameter, wherein the interior wall defining the top cavity is substantially parallel to a vertical axis of the titration vessel;
• a bottom portion, the bottom portion having a wall including a side and a bottom, an interior surface of the side defining a bottom cavity having a second diameter and an interior surface of the bottom enclosing a bottom end of the bottom cavity that is furthest from the top portion, the second diameter less than the first diameter, wherein the interior wall defining the bottom cavity is substantially parallel to the vertical axis of the titration vessel and the second diameter is approximately 10 to 20 millimeters;
• a funneling portion disposed between the top portion and the bottom portion, the funneling portion having an interior funnel wall defining a funnel cavity, the funnel cavity having the first diameter where the funnel cavity adjoins the top cavity and the second diameter where the funnel cavity adjoins the bottom cavity, wherein the funneling portion angles inward at approximately 35 to 65 degrees relative to the vertical axis of the titration vessel;
• and
• a plurality of equidistantly spaced fins protruding outward from an exterior of the side of the wall of the bottom portion of the vessel, the fins attached to the exterior of the side of the wall from an approximate midpoint of the vessel to the bottom of the wall of the bottom portion, wherein bottoms of the fins are level with an exterior surface of the bottom of the wall,
• wherein the titration vessel is a unibody construction.
