Controlling weight gain is an important factor when applying any coating, but it becomes absolutely critical when the coating contains an API. This article presents a case study that identifies the critical process parameters for developing a consistent and robust coating process that provides in-range results. low-dose drug products, although manufacturing highdose products is simpler because ...

A chirped mirror designed with 60 fs2 in group delay dispersion and reflectance large than 97.5% the bandwidth between 700 900 nm by open-sourced thin film filter design software is presented. The mirrors are then fabricated an ion-assisted deposition coater. First, optical constants of films deposited specific process parameters calibrated trial runs single-layer samples measured variable-angl...

Copper oxide (CuO) thin films were deposited on glass substrates by (sol-gel ) method using a spin -Coating technique and the speed of coater was fixed at 3000 rpm for 30 sec samples are annealed temperatures (250,350,450 550) ° C 1 hrs. The structural, Morphology, optical properties film determined X-ray diffraction (XRD), Atomic force microscopy (AFM) UV-visible spectroscopy respectively. XRD...

The objective of this work was to study the coating process of nifedipine extended release pellets using Opadry and Opadry II, in a fluid bed coater with a Wurster insert. The coating process was studied using a complete experimental design of two factors at two levels for each polymer. The variables studied were the inlet air temperature and the coating suspension flow rate. The agglomerate fr...

Particle coating using fluid bed technology such as Wurster chamber is a common process in pharmaceutical technology. Coatings are used to achieve variety of functions, such as: taste masking, controlled release, increase of stability and others. Coating uniformity is one of the most important parameters of coated particles and can play an important role in the release of the active ingredient ...

Coating of particulate solids by a thin film layer is of interest in many industrial applications such as seed and tablet coating. In seed processing, seeds are commonly coated with a protective coating layer consisting of fertilisers and crop protection products. Rotary drum batch coaters are typically used for this purpose. The coater consists of a cylindrical vessel with a rotating spray dis...
