success\u2014or failure\u2014of an entire experiment. Therefore, when working with aggressive chemicals such as strong acids, bases, halogens, or high-temperature oxidizers, it is critical to understand the properties of your reactor vessel to ensure safety, maintain performance, and achieve long-term durability.<\/p>\n<p data-start=\"884\" data-end=\"1204\">This article helps chemical engineers assess when borosilicate glass reactors are ideal for aggressive reactions. Moreover, it explains when it makes sense to consider alternatives such as glass-lined steel, and finally, how HWS Mainz supports both scenarios with custom-built solutions designed for maximum reliability.<\/p>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"What_Defines_an_Aggressive_Chemical\"><\/span>What Defines an Aggressive Chemical?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-start=\"1253\" data-end=\"1294\">Aggressive chemicals are substances that:<\/p>\n<ul data-start=\"1296\" data-end=\"1473\">\n<li data-start=\"1296\" data-end=\"1351\">\n<p data-start=\"1298\" data-end=\"1351\">Cause corrosion or degradation of reactor materials<\/p>\n<\/li>\n<li data-start=\"1352\" data-end=\"1409\">\n<p data-start=\"1354\" data-end=\"1409\">React violently with air, moisture, or other reagents<\/p>\n<\/li>\n<li data-start=\"1410\" data-end=\"1473\">\n<p data-start=\"1412\" data-end=\"1473\">Require elevated temperatures or pressures to remain stable<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1475\" data-end=\"1521\">For example, common aggressive agents include:<\/p>\n<ul data-start=\"1523\" data-end=\"1726\">\n<li data-start=\"1523\" data-end=\"1566\">\n<p data-start=\"1525\" data-end=\"1566\">Strong mineral acids (HCl, H\u2082SO\u2084, HNO\u2083)<\/p>\n<\/li>\n<li data-start=\"1567\" data-end=\"1603\">\n<p data-start=\"1569\" data-end=\"1603\">Organic solvents (THF, DMF, DCM)<\/p>\n<\/li>\n<li data-start=\"1604\" data-end=\"1637\">\n<p data-start=\"1606\" data-end=\"1637\">Halogens (chlorine, fluorine)<\/p>\n<\/li>\n<li data-start=\"1638\" data-end=\"1681\">\n<p data-start=\"1640\" data-end=\"1681\">Oxidizing agents (peroxides, chromates)<\/p>\n<\/li>\n<li data-start=\"1682\" data-end=\"1726\">\n<p data-start=\"1684\" data-end=\"1726\">Bases (NaOH, KOH) at high concentrations<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1728\" data-end=\"1863\">Consequently, choosing the right reactor material means balancing chemical compatibility, mechanical strength, and thermal performance.<\/p>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"Why_Borosilicate_33_Glass_Remains_the_Default_Choice\"><\/span>Why Borosilicate 3.3 Glass Remains the Default Choice<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Borosilicate glass<\/strong>, specifically the 3.3 type used in all <a href=\"https:\/\/www.hws-mainz.de\/pt\/products\/custom-laboratory-glassware\/\">HWS reactors<\/a>, offers exceptional resistance to chemical attack.
