Capsule fillers are devices used to fill empty capsules with powders, granules, or other substances. They streamline the process of creating custom supplements or medications, allowing users to easily measure and encapsulate specific dosages. This is particularly useful for those who prefer to avoid commercial products or need tailored formulations. These fillers come in various sizes and designs, ranging from manual models to more advanced automatic machines. They are commonly used in both home settings and pharmaceutical industries. By using a capsule filler, individuals can ensure consistent filling and maintain the integrity of the contents within the capsules.
