Yes! Our Pro-Op 300 capsule filling system can switch between capsule sizes using optional size-change plates. Sizes #00 through #2 are interchangeable on one machine, and sizes #3 and #4 are interchangeable on a separate machine. Size #000 is a specialty size, so it requires its own dedicated machine.
These numbers tell you how much powder or oil your capsules can hold. The larger the number, the smaller the capsule size: Size 000 is the largest capsule size and size 4 is the smallest.
Because each powder has a different density, the amount of powder that can fit in each capsule goes by the powder’s weight. This chart estimates how much powder (in weight) you can fit in each capsule size.
For comparison, at most the largest capsule size, 000, can hold ~1/2 teaspoon of powder or oil. Every capsule size decreases from there.
Size 00 is the most common capsule size ordered, followed by size 0. You can fit between 1/2 to 3/4ths a gram of powder into one size 00 capsule, and up to a half gram into a size 0.

Very high quality product, well-made, and company is fantastic. My order was delayed only a day or two, through no fault of their own (it was a UPS thing), and they included some bonuses in my order even though I didn't feel they had to. Clearly a well-run company, and their products are superb.
I love this machine. It has speed up my production process and made the production of my product much easier. I strongly recommend buying the Manual Capsule Orienter when you buy the machine. I did not and after having to load the capsules manually in the capsule filler the first time I realized I made a big mistake. I immediately ordered the Orienter! The product is well made and very durable.
I love this machine. It has completely changed my production. It saves me so much time by automatically separating joined capsules, and the stainless steel build feels very professional and reliable. The output is impressive and I love that I can change capsule sizes as my business grows. The customer service was fantastic, very helpful and responsive. Highly recommend this machine!
Package was delivered quickly and without issue. The capsules worked well and had no problems.
