Extran\u00ae detergents from Merck offer a proven solution, delivering thorough, residue-free cleaning for both manual and machine washing needs. Discover how Extran\u00ae supports rigorous cleaning validation, trace detection, and meets the stringent requirements of today&#8217;s laboratory environments.<\/p>\n<h2>Why Choose Extran\u00ae Detergents<\/h2>\n<ul>\n<li><strong>Contamination-free cleaning:<\/strong> Supports contamination-free cleaning of glassware and apparatus for reliable laboratory and production workflows.<\/li>\n<li><strong>Residue-free results:<\/strong> Delivers residue-free cleaning that helps protect analytical experiment integrity and reduce the risk of cross-contamination.<\/li>\n<li><strong>Flexible cleaning use:<\/strong> Supports both manual cleaning and cleaning in laboratory washers to match different laboratory processes.<\/li>\n<li><strong>Validation support:<\/strong> Helps laboratories meet global and local cleaning validation guidelines and regulations with residue analysis support and photometric testing options.<\/li>\n<li><strong>Reduced cleaning validation risk:<\/strong> Minimizes the risk of downtime, batch failures, costly issue tracking, and false rejections associated with inadequate cleaning validation.<\/li>\n<li><strong>Trace detection confidence:<\/strong> Enables reliable trace detection of detergent residues through validated analytical approaches including photometric testing and conductivity assessment.<\/li>\n<li><strong>Environmentally considerate choice:<\/strong> Uses biodegradable active ingredients to support laboratory cleaning with an environmentally friendly formulation.<\/li>\n<\/ul>\n<h2>Key Features and Formulation Attributes<\/h2>\n<ul>\n<li><strong>Product type:<\/strong> Extran detergents are labware detergents formulated for manual cleaning and laboratory washers.<\/li>\n<li><strong>Quality attributes:<\/strong> The formulation portfolio is characterized by consistent product quality, exceptional solubility, and flowability.<\/li>\n<li><strong>Environmental formulation profile:<\/strong> Extran detergents are formulated with biodegradable active ingredients.<\/li>\n<li><strong>Validation-related formulation support:<\/strong> Validation support is available through photometric testing to prove the absence of nonionic surfactants.<\/li>\n<li><strong>Composition exclusions:<\/strong> Extran detergents are free of fragrances, dyes, oxidants, chlorine, enzymes, and NTA.<\/li>\n<li><strong>Safety profile:<\/strong> Safe and non-toxic.<\/li>\n<li><strong>Concentration format:<\/strong> Extran detergents are available as highly concentrated formulations.<\/li>\n<li><strong>Pack size range:<\/strong> Liquid formats are available from 1 L to 25 L, and solid formats are available from 2 kg to 25 kg.<\/li>\n<li><strong>Handling design:<\/strong> The range includes specially designed withdrawal methods and adapters.<\/li>\n<li><strong>Portfolio variants:<\/strong> The product portfolio includes Extran MA and Extran AP variants, as well as acidic rinse neutralizing agents Extran AP 21 with phosphoric acid and Extran AP 22 with citric acid.&nbsp;<\/li>\n<\/ul>\n<h2>Applications and How to Use Extran\u00ae Detergents<\/h2>\n<ul>\n<li><strong>Manual cleaning applications:<\/strong> Extran\u00ae MA detergents are suited for cleaning laboratory apparatus, glassware in cleaning baths, ultrasound equipment, and laboratory surfaces.<\/li>\n<li><strong>Machine cleaning applications:<\/strong> Extran\u00ae AP detergents are developed for machine cleaning in laboratory washers.<\/li>\n<li><strong>Laboratory washers with acid rinse neutralization:<\/strong> Extran\u00ae AP 21 is an acidic rinse neutralizing agent with phosphoric acid, and Extran\u00ae AP 22 is an acidic rinse neutralizing agent with citric acid.<\/li>\n<li><strong>Cleaning validation context:<\/strong> Extran\u00ae detergents are used where cleaning validation is required to establish that an approved cleaning method reproducibly removes residues of active ingredients, inactive ingredients, and cleaning detergent residues to below a pre-determined level.<\/li>\n<li><strong>Swabbing in cleaning validation:<\/strong> Swabbing is described as the preferable sampling method, and for Extran\u00ae products the swab solvent can be water.<\/li>\n<li><strong>Rinsing in cleaning validation:<\/strong> Rinsing is used for larger surface areas and inaccessible systems or systems that cannot be routinely disassembled for sampling and evaluation, and for Extran\u00ae products water can be used as the solvent.<\/li>\n<li><strong>Use selection by cleaning setup:<\/strong> Extran\u00ae detergents can be selected for either manual cleaning workflows or use in lab washers, depending on the cleaning application.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Extran\u00ae Detergents Product Portfolio<\/h2>\n<ul><\/ul>\n<div class=\"res-table-wrapper\">\n<table>\n<tbody>\n<tr
