Aspects to be aware of when selecting and using

1. Material.

Due to the need for corrosion resistant raw materials, so this is no doubt to choose stainless steel 316. Some manufacturers will choose some inferior raw materials, but don't worry, testing the material is very simple, Leave me a message, I will tell you a simple way to detect the material.

2.  Different tablets or capsules require different sizes of dissolution sinker, we can choose through some tests, or provide us with data, our technical staff will give you professional advice.

3.  Size selection.

We will find out in actual use, size is critical for the user, the criteria chosen is that the smaller the contact area between the dissolution sinker and the capsule or tablet, the better, it will affect the dissolution rate.

Note: Choosing the right dissolution sinker is crucial for us. One of my customers has encountered a problem, he used the dissolution sinker, the tablet sank to the bottom, because the mesh of the dissolution sinker is relatively small, pressed on the dissolved heap of the tablet, when the paddle is stirred, the particles will hardly move, the result will be very large, this situation is very common, so we should choose the most suitable sinker.

If there are other questions, please leave a message and let us discuss.
