Abstract
Methods and apparatus to mitigate bubble formation in a liquid are disclosed. An example apparatus disclosed herein includes a bottom wall, a first baffle cantilevered from the bottom wall, and a second baffle cantilevered from the bottom wall. The first baffle is spaced apart from the second baffle, and the first baffle and the second baffle are positioned radially relative to an axis of rotation of the apparatus.
Claims22
A reagent container comprising:
- a first sidewall;
- a second sidewall opposite the first sidewall;
- a first end wall extending between and coupled to the first sidewall and the second sidewall;
- a second end wall opposite the first end wall, the second end wall extending between and coupled to the first sidewall and the second sidewall;
- a bottom wall coupled to the first sidewall and the second sidewall;
- a first baffle extending from the bottom wall, the first baffle spaced apart from the first sidewall and the second sidewall such that a liquid reagent in the reagent container can flow between the first baffle and the first and second sidewalls, the first baffle spaced from the first end wall a first distance;
- a second baffle extending from the bottom wall, the second baffle spaced apart from the first sidewall and the second sidewall such that the liquid reagent in the reagent container can flow between the second baffle and the first and second sidewalls, the second baffle spaced from the first end wall a second distance, the second distance greater than the first distance;
- and
- a top wall coupled to the first sidewall and the second sidewall opposite the bottom wall, an opening defined in the top wall, the opening structured to receive a pipette for extracting the liquid reagent from the reagent container, the opening spaced from the first end wall a third distance, the third distance greater than the first distance, the third distance less than the second distance.
