What, precisely, is a blank cuvette? So, a blank cuvette is a small vessel constructed of transparent material such as glass or plastic. You can find it in a special process called spectrophotometer cuvettes. Here’s a big word that just means that we shine a light through a liquid to see how much light goes through it. This helps us learn things like how much of a certain chemical is in a liquid, whether a liquid is acidic (sour), or basic non-sour
Now you might be wondering, “Why do we need a blank cuvette for this process? Answer: Given this yes, that’s a great question! A blank cuvette contains a liquid similar to that which we will test, except it has no specific analyte we intend to measure. This is quite useful as it helps us improve measurements and achieve accuracy. We measure how much light the blank cuvette absorbs, and subtract that from the how much light the liquid we are really testing absorbs.
So here’s how we might think about it: Say we want to know how much sugar is in a glass of lemonade. Your results could be wrong if a blank glass cuvettes is not used. This is because the lemonade contains substances (other than sugar) that also absorb light. But if you use a blank cuvette instead, you can measure how much light is absorbed by the lemonade and not have those other things messing up the number you’re getting. That way, you get a better sense of how much sugar is in your lemonade, really
To be familiar with what a blank cuvette is and why it is needed, let us discuss how to use the blank cuvette properly. The very first thing you want to make sure of is that your blank cuvette is clean. If there is dirt, leftover chemicals or anything in there, it can either mess with your measurements or lead to an erroneous result. Once the cuvette is clean you add a liquid that is analogous to the one you are analyzing but has none of your target molecule then after filling you place the cuvette in an instrument called a spectrophotometer which tells you how much light is absorbed.
When we do experimental in lab, Blank cuvettes are used very much useful. They make us better and more accurate. For example, suppose you want to find out how much iron is in a water sample. If we do not use a blank glass cuvette the other minerals in the water may interfere and cause us to be unable to obtain an accurate measurement. With a blank cuvette with passage free of those other minerals, you can see how much light the water absorbs without the complication of those other minerals.
Choosing the right blank cuvette is very important for what you require also. These include different types of blank cuvettes made of several materials: glass, quartz, plastic, etc. Each one has its pros and cons. For instance, glass cuvettes have high strength and durability, although can be easy to scratch with little care. Quartz cuvettes can be used with stronger chemicals without breaking, so they can be more expensive. But plastic cuvettes are inexpensive and can be discarded after a single use, though they must be handled with care, as they can’t withstand some liquids.
A little maintenance goes a long way and some of the best practices can even be done with your blank cuvettes. When you finish a cuvette, you should rinse it so that no chemicals remain (preferably, using distilled water). Then wash it in mild soap and rinse it again with distilled water to ensure it’s truly clean. Then, dry the cuvette with a lint-free cloth to make sure no water stains are left. It is also suggested to hold the cleaned cuvette in a protective case to protect it from scratches and damage.
