A cuvette is a tube-like equipment with two straight sides and two circular or straight sides. A test tube is a tubular equipment made of glass or plastic. A cuvette has two straight sides with a rectangular cross-section. A test tube is tubular with a cylindrical shape, having a circular cross-section.

What is a cuvette used for?
Cuvettes are designed to hold samples for spectroscopic measurement, where a beam of light is passed through the sample within the cuvette to measure the absorbance, transmittance, fluorescence intensity, fluorescence polarization, or fluorescence lifetime of the sample.
What are test tubes?
Test tubes are widely used by chemists to handle chemicals, especially for qualitative experiments and assays. Their spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of the contents.
What is a cuvette in biology?
Cuvettes are a small plastic or glass tubes of circular or square cross section, usually sealed at one end. They are used to hold samples for spectroscopic analysis. Cuvettes may be open to the atmosphere at the top or have an additional cap to seal them shut.
What is the test tube called that is used with a spectrophotometer?
However, unlike test tubes, a cuvette is used in a spectrophotometer or a fluorometer to measure the absorbance or % Transmission of light at a specific wavelength. To use a cuvette you simply inject a sample into the cuvette, filling it to about 80% capacity.
How long is a cuvette?
Cuvettes are small rectangular glass or quartz containers. They are often designed so that the light beam travels a distance of 1 cm through the contents, but the path length can vary from 1 or 2 mm all the way up to 10 cm.
How do you clean a cuvette sample?
Wash with nitric acid, 50% is good too, for 10 minutes. Carefully remove the acid. Then wash three times with purified water. Finally rinse with acetone, remove excess and let the cuvette air dry.
Is a test tube baby?
What Is a “Test Tube Baby?” "Test tube baby" is a term sometimes used by the media to refer to children conceived with in vitro fertilization (IVF). Despite the name, "test tube babies" are not developed in a test tube.

What is a cuvette made of?
What Are Cuvette Spectrophotometers Made of? Cuvettes are commonly made from different transparent materials such as optical glass, quartz or transparent plastic. At first sight all such materials appear to be perfectly transparent and fit for all types of absorbance studies.
Does cuvette size affect absorbance?
The absorbance is directly proportional to the length of the light path (l), which is equal to the width of the cuvette.
Do fingerprints absorb light?
The presence of the finger prints will scatter the detector and absorb light causing higher absorbance and higher concentration results. ... yes because it is colorless, and does not absorb visible light and does not have a appreciable molar absorptivity.
