There are many kinds of extraction equipment for urokinase, and it is also
one of the main equipment for producing urokinase products, among which the
chromatography column plays a great role, and the chromatography column is also
the main body of gel chromatography technology, and the extraction tank in the
equipment is also "one of the main members", so how to operate the extraction
1. Before using urokinase, close the slag discharge door and observe
whether it is closed properly (lock it in place and seal it without
2. Urokinase open the feeding door, feed into the tank, and can be water at
the same time, to prevent dust flying, measurement of water intake (loading
volume is generally 70-80%).
3. After feeding urokinase, close the feeding door and observe whether it
is closed properly.
4. Before the temperature rise of urokinase extraction, the valve in the
system should be placed in the "open" or "closed" position according to the
5. Urokinase water extraction, can be directly to the tank through steam
heating, boiling can be changed to the jacket through steam indirect heating
insulation, if the "alcohol extraction", only to the jacket indirect
6. During the extraction process of urokinase in the extraction tank, the
liquid can be pumped out from the lower outlet and pumped into the top inlet of
the tank for forced circulation, so as to make the temperature in the tank
balanced and the extraction effect is sufficient.
7. Urokinase extraction work is completed, you can release the liquid, can
be pumped out, can also use the form of natural flow.
8. Urokinase after the above work is completed, open the slag door, the
residue can be discharged, if the residue is not discharged, can close the slag
door, add a little water and steam to the tank, loosen the residue, and then
open the door to release.
