This machine is of reasonable structure, reliable performance and accurate quantification. It applies pneumatically-driven structure. The shell and all the parts connected with filling materials are made of stainless steel The inner walls of main parts are mirror-polished in roughness Ra≤0.2-0.4µm, which conforms to the requirements of GMP certification. Therefore, it is rustless and corrosion resistant. In addition, the user can adjust the filling volume and speed within the type limitation as required.
