There are many terms and products in the world, which we are unaware of. The cuvette is one of those things that are unique but important in multiple procedures. This laboratory vessel is beneficial for many scientific tests. The crucial part is its quality and type. Both of them must be good for the right findings. Here in this article, we are going to discuss this vessel and types.
What Are Cuvettes?
It is a kind of vessel or a test-tube like a container. The purpose of its invention is to carry out the optical analysis. To avoid refraction artifacts, it can be square or rectangular in cross-section. One end is sealed, whereas the other has a cap or stopper.
It is transparent to capture the optical measurements. They hold a sample and let the light beam to go through it, giving the measurements of transmittance, absorbance, fluorescence, etc.
They can be made up of plastic, fused quartz, or glass. The material of this product depends on the consideration of various spectrums. In the laboratory, measurements through this vessel are done by a spectrophotomer cuvetteLinks to an external site.
Usage of the Spectrophotometer Cuvette:
One has to fill this tube-like container with the sample fluid, but not full. It will help if you are extra careful about it’s the cleaning and fluid range. It shouldn’t be overfilled. Moreover, the container must be clean and dry.
Once the container is filled with the sample, the second step is to place it in the optical instrument. That optical instrument can be fluorometer, spectrometer, or spectrophotometer. Insert the vessel properly in the spectrophotometer, so the beams from the device can pass through the quartz or glass walls of the cuvette. The reason for the entrance of beams is the purity of the container walls.
In simple words, then the beam reads the sample fluid and makes the data ready to get analyzed.
Different Caps and Bottoms:
As the ends are different in these vessels, there are many caps and bottoms. One end is closed, whereas the other end is open and needs the cap according to your experiment. The huge variety makes it difficult to choose from. Some caps may include Teflon lid, Teflon screw cap, Teflon stopper, and silicon lid, etc.
For spectrophotometer containers, round bottoms are mostly used, and for fluorescence ce3lls, flat ones are good.
The Final Words:
It is one of the widely used laboratory equipment. The perfection and purity of such items are a must for correct experiment results. Scratches on its walls may cause errors in your findings. A plastic or rubber covering can protect these containers. Moreover, not only the scratches but the fingerprints and water droplets also affect the solution measurements.
You can use a finger to finger clad method to remove bubbles because there should be no bubbles in the solution. Well, you must be careful while working with a cuvette, especially if the spectrophotometer is also involved. For now, you are aware of all the basics. Hence, this will help you choose one of the right UV cuvettes.
