Softgel Elasticity Testing Machine
Gelatin capsules are one of the most popular types of oral medication delivery systems. They are used for encapsulating liquid or semi-liquid substances, including vitamins, minerals, and pharmaceuticals, providing a protective shell that safeguards the contents from environmental factors. To ensure the quality and safety of gelatin capsules, it is crucial to assess their strength and elasticity.
The Softgel Elasticity Testing Machine is a critical tool for pharmaceutical and nutraceutical manufacturers to evaluate the structural integrity and performance of softgel capsules. This machine is designed to simulate real-world conditions, providing accurate data on the capsule’s ability to withstand forces during handling, transportation, and storage. By performing both penetration and compression tests, the machine offers a comprehensive assessment of the capsule’s mechanical properties.
What is the Softgel Elasticity Testing Machine?

The Softgel Elasticity Testing Machine is a sophisticated instrument designed to assess the mechanical properties of gelatin capsules, including their hardness, elasticity, and seal strength. This machine conducts a variety of tests to determine the force required to rupture the capsule’s wall, its resistance to deformation under compressive load, and the strength of the capsule seal.
The testing machine uses a penetration or compression method with a 10mm-diameter probe, which applies a controlled force to the capsule’s surface. The test simulates real-world stress scenarios, helping manufacturers identify weaknesses in the gelatin film or seal that could compromise the capsule during packaging and transportation. The data gathered from these tests ensures that the capsules meet the required quality standards for strength and durability.
Softgel Elasticity Testing: Measuring Wall Deformation and Strength
Softgel elasticity testing is a critical feature of the Softgel Elasticity Testing Machine. It evaluates how much the capsule’s wall can deform under a specific compressive load before it loses its structural integrity. This elasticity measurement is crucial for understanding the softgel capsule’s behavior under varying pressure conditions.
The machine applies a precise compressive force and measures the resulting deformation. This allows manufacturers to ensure that their softgel capsules are both flexible enough to endure handling and transport, yet strong enough to prevent rupture during use. Testing the elasticity also helps identify any weaknesses in the material, ensuring that the softgel maintains its form and function throughout its lifecycle.
What is Softgel Capsule Made Of?
Softgel capsules are typically made from gelatin, a substance derived from animal collagen, and are commonly used to encase liquid or semi-liquid contents such as oils, extracts, or suspensions. However, there are also vegan alternatives to gelatin, made from plant-based materials such as agar or hydroxypropyl methylcellulose (HPMC). These capsules provide a protective barrier, preserving the active ingredients and enhancing bioavailability.
The Softgel Elasticity Testing Machine helps ensure that these capsules—whether made from traditional gelatin or plant-based alternatives—meet the necessary strength and elasticity standards for optimal performance. By evaluating the physical properties of the capsule wall, the machine provides valuable insights into how the capsule will behave under real-world conditions.
