History Of Microscopes And Microscopes For Sale

Microscopes are a unique tool that allows people to see the tiniest of objects under a magnifying light. Researchers commonly use microscopes to see organisms that are both helpful and harmful to the human body. The optical microscope was the first of its kind; developed in 1590 in the Netherlands. However, the real credit to the first official microscope goes to Galileo for his development in 1625. With centuries of existence behind them, microscopes are still one of the most used tools in the science world today. Today you can find a modern light microscope in nearly any high school, university, hospital and research facility in the world. People use them to analyze everything from living tissue, to blood to cells. The first documented use of microscopes was between 1660 and 1670. They were used in England and Italy to analyze the extensive structure of the lungs. By 1676, Antoni van Leeuwenhoek used microscopes to discover spermatozoa and red blood cells as well as other microorganisms.

Microscopes went through several growing stages over the next three centuries until 1955 when the electron microscope made its début. With this microscope, the user was able to illuminate the slide to get a better view of what he was examining. This made it easier to see and understand the different layers of cells and to watch cell growth. Microscopes have changed the world of education, research and medicine for the better. Without them, we would never be able to see just how amazing each cell in the human body is. If you are looking into microscopes for sale then you should first consider their use. While microscopes typically last for decades with minimal repairs, the parts are often expensive. Additionally, you often have to send a microscope back to the manufacturer for the repairs. Microscopes for sale from a high school or university are likely the best choice because they have been better maintained than most. Additionally, they receive much less use in a classroom setting that those used in a research facility.

Choosing microscopes for sale over purchasing a new one is the best way to get a quality product and save money. You can easily find some of the popular models of microscopes for sale on bidding sites such as eBay.com. Otherwise you can contact the local university or school and ask when they replace equipment and plan to sell the older models. As a general consumer, microscopes are a great way to teach children about cell organisms and gain a better understanding of microorganisms yourself. With the many different types of microscopes available today which include electromagnet, scanning optical and electron microscopes, there is one to fit every need.
