Seitz Filter

A Seitz filter is a method used to separate bacterial cells based on their size and shape. It was developed by the German bacteriologist Eduard Seitz at the end of the 19th century.

The Seitz filter method involves placing bacteria in a solution that contains special particles, such as glass beads or polymer beads. The bacteria are then forced through this solution under pressure. Bacteria that are the right size for the particles remain on the surface of the solution, while those that are too small or too large pass through.

The Seitz filter is widely used in microbiology and biotechnology for the isolation and purification of bacteria. It can also be used to study the shape and size of bacteria, which helps understand their structure and function.

Although the Seitz filter was developed more than 100 years ago, it is still used in modern laboratories and is an important tool for the study of microorganisms.
