This seal features a high-purity, platinum-cured silicone core coated with PTFE (Polytetrafluoroethylene), combining the flexibility of silicone with the exceptional chemical resistance of PTFE. The PTFE coating protects the silicone from chemical attack, ensuring durability and compatibility with aggressive chemicals, making it ideal for applications involving corrosive substances, high-purity solutions, and temperature-sensitive processes. The seal is suitable for use with all sizes of Duran GL 45 laboratory bottles and provides a liquid-tight closure when used in combination with the red PBT GL 45 open-topped screw cap.<\/p>\n<p><strong>Key Features:<\/strong><\/p>\n<ul>\n<li><strong>Brand:<\/strong> DWK Duran<\/li>\n<li><strong>Material:<\/strong> Platinum-cured silicone core with PTFE coating<\/li>\n<li><strong>Compatibility:<\/strong> Fits GL 45 threaded laboratory bottles and glassware<\/li>\n<li><strong>Chemical Resistance:<\/strong> PTFE coating offers high resistance to acids, bases, and solvents<\/li>\n<li><strong>Temperature Range:<\/strong> Stable from -50\u00b0C to +180\u00b0C; autoclavable at 121\u00b0C for 15 minutes; dry heat sterilizable up to 180\u00b0C<\/li>\n<li><strong>Durability:<\/strong> Combines silicone&#8217;s flexibility with PTFE&#8217;s chemical inertness<\/li>\n<li><strong>Leak-Proof Design:<\/strong> Ensures a tight and secure seal, preventing contamination and evaporation<\/li>\n<li><strong>Applications:<\/strong> Ideal for laboratories handling corrosive chemicals, high-purity solutions, and sterile environments<\/li>\n<\/ul>\n<p>This silicone seal is essential for laboratories requiring reliable and chemically resistant sealing solutions for their GL 45 threaded bottles and containers.<\/p>\n<\/div>\n<\/div>\n","protected":false},"featured_media":46355,"template":"","meta":{"content-type":""},"product_brand":[],"product_cat":[11168,11175],"product_tag":[11176],"class_list":["post-46315","product","type-product","status-publish","has-post-thumbnail","product_cat-vessels","product_cat-wide-mouth-bottles","product_tag-laboratoryvesselswide-mouth-bottles","first","instock","sale","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/medqpharmaceuticalsupplies.co.za\/index.php?rest_route=\/wp\/v2\/product\/46315","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/medqpharmaceuticalsupplies.co.za\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/medqpharmaceuticalsupplies.co.za\/index.php?rest_route=\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/medqpharmaceuticalsupplies.co.za\/index.php?rest_route=\/wp\/v2\/media\/46355"}],"wp:attachment":[{"href":"https:\/\/medqpharmaceuticalsupplies.co.za\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=46315"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/medqpharmaceuticalsupplies.co.za\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_brand&post=46315"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/medqpharmaceuticalsupplies.co.za\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=46315"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/medqpharmaceuticalsupplies.co.za\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=46315"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
