1. To the sample, add approximately 50 mL of laboratory water and stir continuously with a glass stirring rod for about two minutes. Let mixture stand for a few minutes to allow the undissolved components settle to the bottom of the mixture. 2. Weigh a clean and dry 250-mL beaker (Beaker #2). Record exact mass.

separators are usually the last stage of magnetic separation to make a final magnetic concentrate and a nonmagnetic tailing. Dry Magnetic Separators (i) Magnetic head-pulley separators are the most common types of dry unit, and can be used both for magnetic particle concentration and tramp iron removal.

Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.
