The capsules are made in two parts by dipping metal rods in molten starch or cellulose solution. The capsules are supplied as closed units to the pharmaceutical manufacturer. Before use, the two halves are separated, the capsule is filled with powder (either by placing a compressed slug of powder into one half of the capsule, or by filling one half of the capsule with loose powder) and the other half of the capsule is pressed on. The two main types of capsules are hard-shelled capsules, which are normally used for dry, powdered ingredients, and soft-shelled capsules, primarily used for oils and for active ingredients that are dissolved or suspended in oil. Starch or cellulose Capsules are available in a range of sizes with designations 000, 00, 0E, 0, 1, 2, 3, and 4. The respective volumetric capacities are 1.37ml, 950µl, 770µl, 680µl, 480µl, 360µl, 270µl, and 200µl. Encapsulation refers to a range of techniques used to enclose medicines in a relatively stable shell known as a capsule, where the highly reproducible filling process helps ensure each Softgel and Hard Shelled Capsules have the same drug content, and the operators are not exposed to any drug dust during the manufacturing process in a highly Sterile Environment involving Hi-end Manufacturing Machines / Equipment.
