Mainly because it has properties that make it useful in various technical processes.<\/p>\n<p>Typical an educational institution, an industrial company or a research facility in need of chemical glassware and other glassware for laboratory use, would look for the properties contained in borosilicates. Lab glass like glass flasks, beaker glasses and testing tubes made of borosilicate glass are the standard choice in many modern laboratories, because a glass tube, vials glass or petri dishes glass made of borosilicate glass has unique properties, that facilitates the needs of modern science.<\/p>\n<p>The glass type has been around since the late 19th century, were it was invented by the German glass pioneer\u00a0Otto Schott, who is also known for having worked closely together with two other german glass pioneers, Carl Zeiss and Dr. Ernst Abbe. As Otto Schott invented the glass in the city of Jena it was for many years also known as Jena glass.<\/p>\n<p>The essence of Borosilicate glass is the special molecular composition\u00a0 that provides the glass with various useful properties. Not only as glassware (Pyrex) in the oven \u2013 but also for business and industrial purposes, where properties like durability and transparency is required.<\/p>\n<p>At Mirit Glas, we are capable of delivering borosilicate glass in many different forms \u2013 especially glass tubes \u2013 and we are happy to help you find a unique solution in the material that fits 100% to your needs.

The glass type has a number of good properties. Borosilicate glass has a greater resistance to scratches than ordinary glass, it can withstand large temperature fluctuations and high temperature, and the glass is resistant to most scratchy chemicals. This makes the glass more durable in stressed environments and makes it a sensible investment.<\/p><p>CAN YOU BREAK BOROSILICATE GLASS INTO PIECES?<br \/>Borosilicate glass is harder and more wear- and scratch-resistant than ordinary glass, but it is not impossible to break. Borosilicate glass, on the other hand, is able to withstand large temperature differences. And it can withstand harsh chemicals. This is why it is also a popular type of glass to use in, for example, laboratories or for refractory dishes, because you can take borosilicate glass straight out of the freezer and into a hot oven.<\/p><h4>IS BOROSILICATE GLASS HAZARDOUS?<\/h4><p>Borosilicate glass is not hazardous to health to use for either food or medicine. In fact, borosilicate glass is almost the only type of glass that is used both for food, in laboratories and for medicine production. When you cannot send borosilicate glass for general glass recycling, it is because the melting point of borosilicate glass is much higher than for ordinary glass &#8211; and not because the glass is dangerous to health.<\/p><h4>IS BOROSILICATE GLASS THE SAME AS PYREX?<\/h4><p>In Europe, PYREX is, as a general rule, the same as borosilicate glass. It is a brand name originally launched by American glass manufacturer Corning as their version of borosilicate glass. In the United States, the trademark is still used as a trademark for laboratory glassware made from borosilicate glass.<\/p><p>In Europe, the brand has today been taken over by a French company, International Cookware, which still uses borosilicate glass to make ovenproof dishes.<\/p><p>In the US and South America, on the other hand, Pyrex became a trademark under the Corelle brands, which at one point replaced borosilicate glass with tempered glass and ordinary glass.<\/p><h4>IS BOROSILICATE GLASS ONLY USED IN LABORATORIES?<\/h4><p>Borosilicate glass is used for many different things from spectacle glasses to splash glasses. It is a very versatile glass that is used for many solutions in the business world. In laboratories and in the pharmaceutical industry, borosilicate glass is almost exclusively used because it can withstand large temperature differences and is resistant to most chemicals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-511f8a1 e-flex e-con-boxed e-con e-parent\" data-id=\"511f8a1\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-f895a33 e-con-full e-flex e-con e-child\" data-id=\"f895a33\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-1e85fb2 elementor-widget elementor-widget-text-editor\" data-id=\"1e85fb2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3><strong>Borosilicate Glass and BOROFLOAT\u00ae 33 \u2013 Properties, Applications and Advantages<\/strong><\/h3><p>Borosilicate glass is one of the most versatile and technically advanced glass types on the market.
