Hello, young scientists! This story is the second entry of a new series called All About the UV: What You Need To Know — And We Will Teach You! When doing a UV spectrophotometric analysis, the sample you want to study is placed inside a small container, called a UV cuvette. This machine allows us to see how much light the sample absorbs. There are different types of UV cuvettes, depending on the material used — quartz, plastic, etc. All these materials have their own pros and cons, which we will discuss in a little detail
Quartz cuvettes are quite common because they glass cuvette allow a significant amount of light to transmit. This allows you to easily visualize what is going on in the sample. They’re also resistant to many chemicals, and they don’t mess with the results we’re trying to obtain. Plastic cuvettes, on the other hand, are less expensive, which is nice, but they carry some disadvantages as well. They transmit less light than quartz and are not resistant to all types of chemicals. Once you select the material you want to work with, you need to select the right path length as well;
Using a quality UV cuvette is very critical for getting the cuvette colorimeter most precise results from your experiment. One example is cuvettes from Jinke Optical, most reliable cuvettes. A high quality cuvette helps give you confidence that your measurements are consistent and reliable. It must be of uniform thickness, so that the light always has the same amount of material to pass through. It must also have a low background noise, which occurs when there are no source signals to interfere with results
There are many advantages when comparing quartz UV cuvettes versus plastic. For one, quartz is more transparent than plastic. This is huge because the more light we have, the better our results when analysing how much light our sample absorbs. Second, quartz is extremely resistant to most chemicals. This means it won't deteriorate or change when it interacts with lots of different things. Plastic, on the other hand, only responds well to certain solvents and can be corrupted by others.
The other advantage of quartz is the lower background noise. Background noise can be any additional signals that can arise from the cuvette itself or from outside. Plastic cuvettes typically have more background noise owing to impurities or other materials in them. At optical elements quartz is more durable than plastic. This allows for better performance at increased temperatures and pressures while maintaining its shape and avoiding breakage, something crucial to systems run under extreme experimental conditions.
Cleaning your UV cuvette properly and maintaining it in good condition is very essential. Cleaning your cuvette allows to remove dirt, fingerprints, and anything else that can interfere with the results of your experiments. You might follow these steps for a proper cuvette cleaning. Wash the cuvette with distilled water first Distilled Water: This type of water is pure and doesn't contain any excess chemicals; cuvette it cannot damage the cuvette.
Rinse it, then dry the cuvette with nitrogen gas or a lens wipe. You want equivalent lint-free cloth, because a regular cloth leaves behind little pieces of fabric that will obstruct the way. The imaging flow cytometry clean parts of the cuvette should never be touched with your fingers if you can help it. Your fingerprints (and oils from your skin) can create issues with how light passes through the cuvette.
