Tilting liquid storage container for either oblique or vertical entry of pipets

A laboratory liquid storage container comprising:

• a body having at least two side walls, a first support wall surface and a second support wall surface angularly disposed in relation to said first support wall surface;
• said body having a first upper wall surface opposite said first support wall surface and a second upper wall surface opposite said second support wall surface, each side wall having a height between the first upper wall surface and the first support wall surface that is less than the maximum width of the sidewall measured perpendicular to its height;
• a neck extending upwardly about an axis from said first upper wall surface and defining a neck opening, said neck opening being asymmetrically positioned in said first upper wall surface adjacent said second upper wall surface;
• wherein said body can be positioned in a first resting position with said first support wall surface in a substantially horizontal plane and said neck disposed about a substantially vertical axis, and in a second resting position with said second support wall surface in a substantially horizontal plane and said neck disposed about an axis tilted from said substantially vertical axis;
• and
• wherein at least one of said side walls has volumetric graduation markings, respectively oriented for use with the container in at least one of said resting positions.
