Band Aid Dilemma

What is an autoclave sterilizer used for?


Science and technology can be very confusing and sometimes hard to understand. Countless chemical reactions are produced every second in the atmosphere, and you may end up missing all the beauty if you’re not familiar with the terminology and the science behind these processes.

In today’s episode, I would want to talk to you about another great machine that is used for a variety of purposes – the autoclave sterilizer. Here is everything you need to know about what it is and how it works.


What is an autoclave sterilizer?

The autoclave was invented about 130 years ago by Charles Chamberland and it represents a pressure chamber that uses the power of steam and pressure to carry out various industrial processes. Ever since its invention, this machine managed to save thousands of lives since it is often used in the medical industry to sterilize hospital equipment.

The autoclave uses the power of pressurized saturated steam at approximately 249 degrees Fahrenheit. Depending on the content and the purpose of its use, the machine takes 15-20 minutes to complete a sterilizing cycle.


What are the uses of an autoclave sterilizer?

This fascinating device is widely used in fields like medicine, microbiology, veterinary medicine, funerary practices or dentistry. The autoclaves can also be used in the food industry in factories that process ingredients and require a sterile work environment.

The typical loads you can find inside this device are surgical instruments, laboratory glassware or even medical waste. It was recently discovered that the autoclave could be successfully used in the medical waste industry.

With the help of superheated water and pressurized steam, the machine can neutralize all potentially infectious agents and reduce the risk of nosocomial infections in hospitals or medical labs.


The beauty industry

Autoclave sterilizers vary in size and load capacity and can also be used in the beauty industry. Tattoo artists and body painters often use small-sized autoclaves to sterilize their equipment before using it on a client’s body. Body piercings undergo similar safety procedures before penetrating the skin.

These professional steam devices are crucial if you want to ensure the safety of your salon’s clients, as well as your own safety. Human skin is highly sensitive and prone to a variety of bacterial infections that can lead to further complicated diseases and affections.

If you cannot afford to buy your own autoclave for your shop, there are other methods of sterilizing your equipment. To avoid any suspicions, you can also opt for disposable or single-use tools, especially when it comes to needles. The rest of the equipment can be sterilized using alcohol solutions.


What is a refractometer and what can it be used for?


Most people feel clueless when reading science books because they don’t find the information engaging and easy to read. After years of trying to get to the bottom of it, I’ve managed to develop my passion for this beautiful art and I want to share with you a little bit of my knowledge. Since I know how difficult it is to understand these complicated terms, I did my best to simplify the process and leave only the essential regarding the refractometer and its usages.

A refractometer is a useful but also simple tool used for measuring the extent to which light is either bent or retracted when moving through a certain type of substance. When light enters a liquid it automatically changes direction. This process is called refraction, hence the name of the refractometer.

The reason it provides accurate results is that light travels at different velocities, depending on the environment. The most important aspect is that it requires only a few drops of liquid and can be used as lab equipment for various industries such as food, agriculture, chemical industries, and manufacturing.


Even though refractometers are all the same, they do differ in terms of their optical part. Each model features a special scale where you can see the results instantly or you need to calculate the results based on the values measured by a versatile refractometer.

The refractometer is quite easy to handle and the measurements are taken rapidly. If you place a few drops of liquid on the prism and you press them without using force, the bubbles and the air are eliminated. Then, look through the eyepiece ad aim to the light. You’ll see a combination of a white and blue boundary which provides you the value of the measurement.

As far as their utility, refractometers are specially designed for a multitude of operations that include measuring liquids. Most of them use oils or water-based liquids, translucent solids, and gases. In agriculture, refractometers require the refractive light that passes through the plant sap in order to get nutrient levels.

Also, refractometers come in handy for providing drug diagnosis, for various operations in the veterinary medicine field, or got the upkeep of aquariums. Refractometers come in four main types, such as traditional handheld, digital handheld, laboratory, and inline process refractometers. Furthermore, automatic refractometers have been developed. These units are microprocessor-controlled electronic instruments that can be combined with other types of measuring devices.

There are tools that feature universal units on their scale. These are the refractometers for measuring the refractive index and the refractometer with Brix scale. One major advantage this type of refractometers has is that it allows you to measure any kind of liquid if you know how to convert the measured value to a known characteristic.




Home Lab: Exciting Experiments by Robert Winston Review


I’ve always been passionate about science, although I have to admit that I wasn’t the same while I was growing up. School was always a pain, particularly because many of my science teachers weren’t particularly gifted, and so they found it very hard to explain to us kids the wonders of the world around us.

I did most of my learning through reading. Each time I found out about a new book about experiments you could do at home, I raised some money and bought it. These days, I own a Kindle, so it’s way more convenient for me to find out about new books. Plus, they are much cheaper compared to their hardcover counterparts, which is always a plus.


Home Lab: Exciting Experiments, by Robert Winston was a book I came across while searching for one that I could use with my nephew. It’s unfortunate that kids nowadays don’t have the opportunities that we used to have back in the day, which is to say that they spend more of their time in front of a display than they would outside, actually tasting freedom.

My nephew is six-years-old, so there are many things that still amaze him, despite the fact that he is intelligent and resourceful. The coolest thing about this book is that it is packed with a myriad of experiments. Each of them is thoroughly explained thanks to a set of detailed instructions so that both you and the child get to understand what you are supposed to do.

We all know how frustrating scientific terminology can really be, even for an adult. It’s pretty frustrating for a kid to find him or herself feeling baffled because they don’t know what to do. Home Lab: Exciting Experiments for Budding Scientists is one of those books that doesn’t get you in trouble. It is detailed, simple to read and grasp, and it comes with an impressive number of pictures and diagrams that make everything a lot easier than you’d initially think.

Both the instructions and the colorful layout are highly spoken of by those who have purchased the book for their children. So, I’m not the only one. Of course, I had to do my homework before buying the book because I wasn’t just willing to pick one and get it over with. I actually wanted something that my nephew could use, preferably in my presence or with my help. I love giving him a hand with his science projects, so I always make sure to make some time for him during the weekends.

In short, if you are looking for a fun science book for the young ones, perhaps you should give a shot to Home Lab: Exciting Experiments.
