'das Muster' and 'der Tester' can both be a small amount or an item used to try something out. 'Muster' is often used when a sample is meant to show what the whole product is like, for example with fabric, paint, or material. 'Tester' fits especially for products that you try directly, such as perfume or cosmetics, or for a device used for checking something. The words can be confused because both can help before a purchase or before making a decision. 'Muster' emphasizes the sample as an example; 'Tester' emphasizes trying or checking something.
