More than a compliance task, tablet hardness testing helps manufacturers control formulation consistency, evaluate production processes, and improve product performance.<\/p>\n\n\n\n<p>Cell Instruments offers precision solutions like the <strong>MPT-02 Tablet Hardness Tester<\/strong> to support the evolving needs of quality assurance teams and R&amp;D laboratories.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Tablet Hardness Matters in Pharmaceutical Quality Control<\/h2>\n\n\n\n<p>Tablet hardness\u2014also referred to as tablet breaking force\u2014is a vital characteristic affecting tablet integrity, disintegration, and dissolution. According to <strong>USP &lt;1217&gt;<\/strong>, tablet hardness is not simply a measure of strength; it\u2019s an indicator of the tablet\u2019s ability to resist mechanical stress without compromising therapeutic efficacy.<\/p>\n\n\n\n<p><strong>Key Implications of Tablet Hardness Testing:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ensures tablet integrity during <strong>coating, packaging<\/strong>, and <strong>transport<\/strong><\/li>\n\n\n\n<li>Helps optimize formulation during development<\/li>\n\n\n\n<li>Ensures dosage uniformity and bioavailability<\/li>\n\n\n\n<li>Complies with regulatory standards like <strong>USP &lt;1217&gt;<\/strong><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Core Tablet Testing Methods Under USP &lt;1217&gt;<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Tablet Hardness Test (Crushing Strength Method)<\/h3>\n\n\n\n<p>The most common approach is the <strong>crushing strength method<\/strong>, where a tablet is compressed between two platens until it breaks. The force required is recorded as the <strong>tablettens h\u00e5rdhet<\/strong>.<\/p>\n\n\n\n<p><strong>Equation for tensile strength (round tablets):<\/strong><br>\u03c3 = 2F \/ (\u03c0 \u00d7 D \u00d7 H)<br>Where:<br>F = Breaking force, D = Tablet diameter, H = Tablet thickness<\/p>\n\n\n\n<p>This test is essential for tablets that must endure robust handling without crumbling, particularly during packaging and distribution.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Compression Test<\/h2>\n\n\n\n<p>This is a <strong>mechanical stress test<\/strong> that mimics the real-world conditions tablets face during packaging and transport. It measures how much compressive force a tablet can tolerate before deformation or breakage.<\/p>\n\n\n\n<p>The <strong>MPT-02<\/strong>from Cell Instruments allows controlled compression force, providing <strong>accurate and repeatable<\/strong> results.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"H\u00e5rdhetstestning av tabletter Kompressionsh\u00e5rdhetstest f\u00f6r l\u00e4kemedelstabletter\" width=\"1020\" height=\"574\" src=\"https:\/\/www.youtube.com\/embed\/uYgafVVSvpY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Tablet Friability Test<\/h2>\n\n\n\n<p>Friability testing evaluates a tablet\u2019s resistance to surface wear and chipping. Tablets are tumbled in a rotating drum and then reweighed. The <strong>USP &lt;1216&gt;<\/strong> standard recommends a <strong>maximum weight loss of 1.0%<\/strong> as acceptable.<\/p>\n\n\n\n<p>This test is essential to ensure tablets remain intact without excessive dusting or cracking.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Three-Point Bending Test<\/h2>\n\n\n\n<p>For tablets that are long, oval, or scored, the <strong>three-point bending test<\/strong> is more suitable. It measures the <strong>tablet breaking force<\/strong> by supporting it at two points while applying pressure at the midpoint until it fractures.<\/p>\n\n\n\n<p>This method is particularly useful for evaluating <strong>chewable or scored tablets<\/strong> and is available as an optional feature with the MPT-02 system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key Secondary Tests and Parameters<\/h2>\n\n\n\n<p><strong>Tablet Thickness<\/strong>: A critical physical parameter affecting uniformity and tensile strength calculations.<\/p>\n\n\n\n<p><strong>Friability of Tablet<\/strong>: Helps identify poorly bonded or overly dry formulations.<\/p>\n\n\n\n<p><strong>Tablet Brittleness Test<\/strong>: Evaluates a tablet\u2019s tendency to fracture under low force or impact.<\/p>\n\n\n\n<p><strong>Tablet Strength<\/strong>: A general term combining compressive and tensile strength parameters to assess durability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Choosing the Right Tablet Hardness Tester<\/h2>\n\n\n\n<p>When selecting a <strong>tablet hardness tester<\/strong>, look for precision, reliability, and compliance with pharmacopeial standards.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why Choose the MPT-02 Tablet Hardness Tester?<\/h3>\n\n\n\n<p>Cell Instruments\u2019 <a href=\"https:\/\/www.tablethardness.com\/sv\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>MPT-02<\/strong> <\/a>offers advanced functionality designed for pharmaceutical quality control:<\/p>\n\n\n\n<div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-ad2f72ca wp-block-group-is-layout-flex\">\n<ul class=\"wp-block-list\">\n<li><strong>High-Precision Loadcell<\/strong> for accurate force measurement<\/li>\n\n\n\n<li><strong>7-inch HMI touchscreen<\/strong> for intuitive operation<\/li>\n\n\n\n<li><strong>Real-time data visualization<\/strong> and microprinter for instant output<\/li>\n\n\n\n<li><strong>Multiple test modes<\/strong>: crushing, compression, and optional three-point bending<\/li>\n\n\n\n<li><strong>USP &lt;1217&gt; compliance<\/strong>, suitable for R&amp;D and production lines<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"977\" height=\"1024\" src=\"https:\/\/www.tablethardness.com\/wp-content\/uploads\/2025\/08\/tablet-hardnesstester-1zon-1-977x1024.webp\" alt=\"test av tablettens h\u00e5rdhet\" class=\"wp-image-1299\" style=\"width:361px;height:auto\" srcset=\"https:\/\/www.tablethardness.com\/wp-content\/uploads\/2025\/08\/tablet-hardnesstester-1zon-1-977x1024.webp 977w, https:\/\/www.tablethardness.com\/wp-content\/uploads\/2025\/08\/tablet-hardnesstester-1zon-1-286x300.webp 286w, https:\/\/www.tablethardness.com\/wp-content\/uploads\/2025\/08\/tablet-hardnesstester-1zon-1-768x805.webp 768w, https:\/\/www.tablethardness.com\/wp-content\/uploads\/2025\/08\/tablet-hardnesstester-1zon-1-1466x1536.webp 1466w, https:\/\/www.tablethardness.com\/wp-content\/uploads\/2025\/08\/tablet-hardnesstester-1zon-1-1954x2048.webp 1954w\" sizes=\"(max-width: 977px) 100vw, 977px\" \/><figcaption class=\"wp-element-caption\"><br><\/figcaption><\/figure>\n<\/div>\n\n\n\n<p>Its flexible fixture system supports a variety of tablet shapes and sizes, making it ideal for tablets with complex geometries.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Best Practices for Reliable Tablet Hardness Testing<\/h2>\n\n\n\n<p><strong>Calibrate testers regularly<\/strong> with traceable weights<\/p>\n\n\n\n<p><strong>Test at consistent loading rates<\/strong> (e.g., \u2264 20 N\/s or \u2264 3.5 mm\/s)<\/p>\n\n\n\n<p><strong>Use padding<\/strong> for tensile-strength-focused tests (optional)<\/p>\n\n\n\n<p><strong>Ensure consistent tablet orientation<\/strong> during every test<\/p>\n\n\n\n<p><strong>Test at least 6 tablets<\/strong> for statistically meaningful results<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Tablet hardness testing plays a pivotal role in pharmaceutical quality control.
