A sample sieve is a tool used for separating and analyzing materials based on particle size. It typically consists of a mesh screen or woven mesh disc housed within a frame. Here are some key points about sample sieves:

Characteristics
Material: Often made from stainless steel, plastic, or brass, depending on the application and required durability.
Mesh Size: The mesh size can vary widely, allowing for the separation of different particle sizes. Common mesh sizes range from coarse to fine.
Shape: Usually circular, but can also be rectangular or square, depending on the design and application.
