It&#8217;s also called a temperature chamber. Most units run between 4\u00b0C and 60\u00b0C, with humidity from 20% to 95% RH, logging conditions continuously so the data can be submitted with a drug application. Bionics Scientific has built this kind of equipment for 35 years and supplies <\/span><a href=\"https:\/\/www.bionicsscientific.com\/blogs\/stability-chambers-pharmaceutical\/\"><span style=\"font-weight: 400;\">stability chambers<\/span><\/a><span style=\"font-weight: 400;\"> to pharmaceutical, biotech, and CRO facilities in India and abroad.<\/span><\/p>\n<h2><b>What Is a Stability Chamber in Pharma?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">A stability chamber is a sealed enclosure built to hold a specific temperature and humidity for months or years while a product is checked periodically for degradation. This isn&#8217;t cosmetic\u2014regulators like the USFDA, EMA, and CDSCO require this data before approving a submission, under conditions set by ICH Q1A(R2).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">What separates a pharma-grade chamber from a regular incubator is tolerance: it typically needs to hold within \u00b12\u00b0C and \u00b15% RH, consistently across the whole interior, not just near the sensor. One bad reading can invalidate months of data\u2014which is why airflow, sensor placement, and humidity method matter more here than in most lab equipment.<\/span><\/p>\n<h2><b>Why Stability Testing Cannot Be Skipped<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The world is divided into four ICH climatic zones (I\u2013IVb) by ambient temperature and humidity. A tablet stored in Lagos degrades differently than one in Reykjavik, so a stability chamber recreates those conditions in-house instead of shipping product to every region.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This data determines:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The shelf life on the label<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Storage instructions, like &#8220;store below 25\u00b0C&#8221;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Packaging choices\u2014blister vs. bottle, desiccant needs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Whether a formulation change requires re-filing<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Skipping or under-documenting this step is a common cause of regulatory query letters and rejections.<\/span><\/p>\n<h2><b>Climatic Zones and Testing Conditions<\/b><\/h2>\n<p>A <strong data-start=\"601\" data-end=\"632\">stability chamber in pharma<\/strong> can be configured according to the temperature and humidity conditions required for specific stability testing protocols.<\/p>\n<table>\n<tbody>\n<tr>\n<td><b>ICH Zone<\/b><\/td>\n<td><b>Definition<\/b><\/td>\n<td><b>Long-Term Condition<\/b><\/td>\n<td><b>Intermediate<\/b><\/td>\n<td><b>Accelerated<\/b><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Zone I<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Temperate<\/span><\/td>\n<td><span style=\"font-weight: 400;\">21\u00b0C \/ 45% RH<\/span><\/td>\n<td><span style=\"font-weight: 400;\">\u2014<\/span><\/td>\n<td><span style=\"font-weight: 400;\">40\u00b0C \/ 75% RH<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Zone II<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Mediterranean\/subtropical<\/span><\/td>\n<td><span style=\"font-weight: 400;\">25\u00b0C \/ 60% RH<\/span><\/td>\n<td><span style=\"font-weight: 400;\">30\u00b0C \/ 65% RH<\/span><\/td>\n<td><span style=\"font-weight: 400;\">40\u00b0C \/ 75% RH<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Zone III<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Hot, dry<\/span><\/td>\n<td><span style=\"font-weight: 400;\">30\u00b0C \/ 35% RH<\/span><\/td>\n<td><span style=\"font-weight: 400;\">\u2014<\/span><\/td>\n<td><span style=\"font-weight: 400;\">40\u00b0C \/ 75% RH<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Zone IVa<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Hot, humid<\/span><\/td>\n<td><span style=\"font-weight: 400;\">30\u00b0C \/ 65% RH<\/span><\/td>\n<td><span style=\"font-weight: 400;\">\u2014<\/span><\/td>\n<td><span style=\"font-weight: 400;\">40\u00b0C \/ 75% RH<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Zone IVb<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Hot, very humid<\/span><\/td>\n<td><span style=\"font-weight: 400;\">30\u00b0C \/ 75% RH<\/span><\/td>\n<td><span style=\"font-weight: 400;\">\u2014<\/span><\/td>\n<td><span style=\"font-weight: 400;\">40\u00b0C \/ 75% RH<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"font-weight: 400;\">Most chambers are set to one condition at a time.
