Abstract
Technology described herein includes a method that includes providing, by an optical light source, a light beam configured to traverse an optical path through a fluid comprising the biological sample in a container. A length of the optical path through the fluid is between 3.3 mm to 5.5 mm, and a center of the light beam is at a height less than 1.6 mm from a bottom interior surface of the container, and a volume of the fluid is less than 120 μL. An optical detector receives optical information after the light beam traverses the optical path. An output of the optical detector is associated with at least one parameter representing the one or more characteristics of the biological sample.
Claims8
A system for determining one or more characteristics of a biological sample, the system comprising:
- a cuvette configured to contain a fluid comprising the biological sample, where a volume of the fluid to be contained is less than 120 μL, wherein the cuvette comprises at least one pair of opposing surfaces that are substantially parallel to each other, the at least one pair of opposing surfaces defining a portion of the cuvette into which the fluid is dispensed or from which the fluid is aspirated, wherein a length of a portion of the cuvette configured to contain the fluid is between 3.3 mm to 5.5 mm and a width of the portion is between 3.3 mm to 5.5 mm;
- a probe configured to dispense the fluid into the cuvette or aspirate a portion of the fluid from the cuvette;
- an optical source external to the cuvette and the probe, the optical source disposed to provide a light beam through the cuvette, the light beam configured to traverse an optical path through the fluid in the cuvette along a direction substantially perpendicular to the at least one pair of opposing surfaces, the optical source being positioned external to the cuvette such that a center of the light beam is at a height less than 1.6 mm from a bottom interior surface of the cuvette;
- and
- an optical detector configured to receive optical information after the light beam traverses the optical path, wherein an output of the optical detector is associated with at least one parameter representing the one or more characteristics of the biological sample.
