Test tube racks are as essential as test tubes used in scientific labs. There is no doubt about the same. The racks are important for the efficient use and movement of the test tubes in the lab. If you are using them, you know how essential a test tube rack is to science students and researchers. If you are new, then you are reading the right article.
The racks come with a rounded base and are an essential design feature built with a purpose. It helps in reducing the spillage or loss of fluids while you pour from a test tube. The racks eliminate the corners that you may find a cumbersome task to clean. When heating a tube, the distribution of heat is uniform when the glassware is held above a flame. Read on to learn more about test tube racks.
Test tubes racks available in many styles
When it comes to test tube racks, you will find them in a range of design and styles. A couple of designs will serve a definite purpose while the rest are used as per your budget and convenience. Let us explain this point with the help of an example. For instance, if you consider wire racks, they are light, extremely heat resistant, and you can view the tubes when these items are placed in the rack.
If you opt for plastic racks, these are less resistant to heat, but easy on the wallet when manufactured in large scale. You will find plastic test tube racks in a range of brilliant colors as well.
There is another variety, which is foam test tube rack. You can use them to move test tubes but also let them float in water baths.
You will also find racks or tube holders that interconnect to help you transport multiple tubes. You can stack other varieties for safe storage when you are not using them.
Safe movement of test tubes
You can move empty test tubes using your hand or carry them in the pocket of your lab jacket. Then, when you want to transport large quantities of tubes or those containing harsh and unsafe chemicals, you will need to use test tube racks.
You will also need these racks if you want to conduct comparative analysis and tests or collect numerous samples. Again, if you work with sulfuric or hydrochloric acid that is damaging to the skin, you must use a test tube stand. After all, safety matters the most when you are experimenting with hazardous fluids or chemicals in a scientific laboratory.
Prevents tilting
These racks support tubes in vertical wells, thus preventing the glassware from tilting. A few of the tube holders come with wells with an extremely narrow tolerance and hold the test tubes in a safe way in a vertical position.
Then, you will find other racks with wider diameters that let the test tubes slant a little. This way, there is no possibility of liquid or chemical spillage. It helps in maintaining safety precautions in a scientific laboratory.
Conclusion
Now that you know about test tube racks in labs, make an informed decision when you need them for use. Maintain safety precautions while using tubes and racks in a lab.
