SEE THE PRO-OP 300 IN ACTION!

CHANGE CAPSULE SIZES

Unlike all our other machines, the Pro-Op 300 can be equipped with additional size change plates, so that you can use the same machine to make different-sized capsules.

USE JOINED CAPSULES

Our Pro-Op Series have one significant advantage over our Core & Pro Series machines... they separate joined capsules for you! Saving you time from doing it manually OR saving you money from buying pre-separated capsules. This is the machine you've been waiting for.

GMP/CGMP COMPLIANT

Being completely made of stainless steel, it meets all the regulation requirements for your industrial operation/business.

FREQUENTLY ASKED QUESTIONS

Can you use different size capsules in the same machine? Plus

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.

What do the sizes 000-4 mean? Plus

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.

Which size do most people buy? Plus

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.
