Systems and methods for positioning sensors in biopharmaceutical storage containers

A positioning system comprising:

• a base having a first side and a second side opposite the first side;
• a first holder secured to the base, the first holder defining a first receptacle and a first holder axis that extends through the first receptacle orthogonal to the first side of the base, the first holder configured to receive a first beam generator that emits a first light beam through the base coaxial with the first holder axis;
• and
• a second holder secured to the base, the second holder defining a second receptacle and a second holder axis that extends through the second receptacle askew to the first holder axis such that the first holder axis and the second holder axis intersect at a predetermined distance from the second side of the base, the second holder configured to receive a second beam generator that emits a second light beam through the base coaxial with the second holder axis, the second holder axis spaced apart from the first holder axis at the first side of the base.
