What is corer?

A corer is a tool or instrument used for removing a cylindrical sample or core from a larger object. It is commonly used in fields such as geology, biology, and agriculture for the collection of soil, rock, and plant samples. There are many different types of corers, each designed for a specific use, such as an ice corer for extracting ice cores, a soil corer for retrieving soil samples, a fruit corer for removing the core of fruits, and a biopsy corer for taking tissue samples from living organisms. Corers can either be manually operated or powered by electricity or compressed air. They are used in various industries and research fields for analysis, experimentation, and testing.
