Polishing Pan
Product Code : SCL-CLE-11453
Description:
The Laboratory Polishing Pan, also widely known as a Coating Pan or Pill Coating Machine, is a specialized piece of Science Educational Laboratory Equipment primarily used in Pharmacy (Pharmaceutics) and Chemical Engineering labs. It is critical for the final stages of manufacturing solid dosage forms, specifically for applying coatings to tablets and granules.
Function: Provides a rotating, inclined surface where pharmaceutical solids are tumbled and sprayed with a liquid coating solution (often containing polymers, colorants, and other excipients). This process ensures a uniform, smooth, and aesthetically pleasing finish.
Key Purpose:
Aesthetics and Identification: To give tablets a desired color and polished appearance for easy identification.
Protection: To protect the drug from environmental factors (like moisture and air) and to mask unpleasant tastes or odors.
Controlled Release: Used for applying enteric coatings that delay drug release until the tablet reaches a specific part of the digestive tract.
Design: Features a rotating pan, adjustable inclination, and often incorporates a hot air system to facilitate rapid drying of the applied coating.
Usage:
The Polishing Pan is vital for practical training in pharmaceutical formulation and manufacturing processes:
Tablet Coating Studies: Used by pharmacy students to learn and practice various coating techniques, including sugar coating and film coating, and to study the parameters that affect coating quality (e.g., pan speed, spray rate, air temperature).
Granulation and Pelletizing: Can be used in preliminary stages for mixing and forming granules or pellets before final coating.
Quality Control Training: Allows students to produce coated products and then test them for dissolution rate, uniformity of weight, and tablet hardness, linking theory to practical quality assurance standards.
Material Science: Relevant for teaching concepts of surface adhesion, film formation, and controlled-release mechanisms.
