Celite, acid-washed, is widely used as a filtration aid in various industries. In laboratories, it is commonly employed to clarify liquids by removing fine particles and impurities during the filtration process. It is particularly useful in the preparation of samples for analysis, such as in HPLC or GC, where clean and particle-free solutions are essential. Specifically, it is used in the analysis of total dietary fiber content (TDF-100A method).

In the food and beverage industry, it is used to filter and clarify products like beer, wine, and fruit juices, ensuring a clear and visually appealing final product. Additionally, it finds application in the pharmaceutical industry for purifying drug solutions and suspensions. Its acid-washed nature makes it suitable for applications requiring low levels of trace metals or contaminants, ensuring high purity in sensitive processes.
