Abstract:

A fluid-holding vessel () with a surface tension reducing geometry which comprises an inner surface having striations () and a fluid transfer method are disclosed and described. The fluid-holding vessel () may be a test tube that is used in combination with a cap (), which is penetrable by a fluid transfer device () of an automated analyzer () used to transfer fluids to or from the striated test tube, where the tube and cap may remain physically and sealably associated during a fluid transfer. The automated analyzer () may be used in combination with the fluid-holding vessel () as disclosed and described herein, in which the surface tension reducing geometry () of the vessel () addresses an aspiration problem of a liquid () dispensed therefrom automatically by the automated analyzer (), e.g., into a sample cup.
