Size 1 capsule filling machine: for small doses and strong extracts
Size 1 is the smallest capsule size in the standard range. A capsule of this size holds approximately 400 mg of powder, depending on the density of the material. This makes size 1 suitable for herbs and extracts where you want a relatively low dose per capsule, or where the powder is compact and heavy. For kanna or potent herbal extracts, size 1 is a practical choice. For kratom, which is used in doses of 2 grams and higher, sizes 00 or 000 are generally more efficient because you’ll need fewer capsules per dose.
How does the capsule filling machine work?
The machine uses a two-part frame. Place the bottom halves of 24 empty capsules into the lower part of the frame. Next, sprinkle the finely ground powder over the frame and distribute it using the included distribution card until each capsule is evenly filled. If necessary, tamp the contents down further with the tamper for a higher fill level. Then place the frame with the upper halves of the capsules on top and press both halves together in one motion. Result: 24 filled and sealed capsules.
Make sure the powder is ground finely enough for even distribution. Coarse material fills the capsules unevenly, causing the dose per capsule to vary. A coffee grinder or food processor yields the best results. For accurate dosing per capsule, first weigh the total batch of powder using a precision scale such as the MTT-100 (0.005 g accuracy) or, for even finer doses, the On Balance SEN-250 SENSO (0.001 g). This way, you’ll know exactly how much active ingredient is in each capsule on average. Check out the full range of precision scales for more options.
Empty capsules for size 1 machines
This machine works exclusively with size 1 capsules. Both gelatin and vegetarian HPMC capsules in size 1 are available in the empty capsules category. Gelatin capsules dissolve faster in the stomach. Vegetarian capsules are suitable for people who do not consume animal products. Both varieties are available in packs of 100.
Frequently Asked Questions
How much powder fits in a size 1 capsule?
A size 1 capsule holds approximately 400 mg of powder, depending on the density of the material. Light, airy powder fills less compactly than heavy, finely ground powder. Weigh the total batch and divide by 24 to calculate the average amount per capsule.
Does this machine also work with size 0 or 00 capsules?
No. The machine is specifically designed for size 1 capsules. Capsules of other sizes do not fit properly in the frame, leading to poor sealing and uneven filling. Separate machines are available for sizes 0, 00, or 000 in the empty capsules category.
How do I ensure even filling?
Grind the powder finely with a coffee grinder before you begin. Sprinkle the powder generously over the frame and use the distribution card in a sweeping motion until all capsules are evenly filled. Tamp down if necessary and repeat. Weigh the batch beforehand to check the dose per capsule.
