	Cuvette
		A cuvette is a kind of laboratory glassware, usually a small square tube, sealed at one end, made of plastic, glass, or optical grade quartz and designed to hold samples for spectroscopic experiments.
		Cuvettes to be used in circular dichroism experiments should never be mechanically stressed, as the stress will induce polarization of the glass and affect the measurements made.
		While some cuvettes will be clear only on opposite sides, so that they pass a single beam of light through that pair of sides (often the unclear sides have ridges or are rough to allow for ease of handling), cuvettes to be used in fluorescence spectroscopy[?] are clear on all 4 sides.

	Embryo Sorter Website - Optics Cuvette
		The cuvette serves several functions: 1) to isolate the fluid system from the optical system as much as possible, 2) to deliver embryos to the excitation light in a single file fashion, and 3) to emit embryos from the system in a fluid stream that is easily diverted.
		The inside of the cuvette, surrounding the square glass tube, was filled with immersion oil using a small opening on the other side of the cuvette (panel E).
		Panel G is an end-on view of the optics cuvette, showing the central opening where the embryos exit.

		Special PTFE caps with needle holes seal the cuvette when the liquid is volatile or when the cuvette is turned upside down for bubble-up measurements.
		Special care must be taken to not dirty the outside of the cuvette while handling it, because the microscope must look through the sides to see the drop.
		Fill the cuvette while it is standing on the bench, and insert the cap and needle, following the previous general instructions.

	Setting up a colorimetric assay
		A cuvette is a transparent vessel to be placed in a light path for measurement of absorbance.
		However, at very low absorbances one or more unknown factors, such as a defect in the sample tube or cuvette, will have a more profound effect on the absorbance value than at higher absorbanced.
		At the upper end of the range the color reagent approaches saturation, so that not only do you have less resolution among absorbance readings, but the reagent is less sensitive to differences in protein concentration.
