Cork Borer (Agar Plate Hole Puncher) is a laboratory tool designed for punching clean, consistent circular wells in agar plates and other soft materials.

It is commonly used in microbiology and diffusion assays to create wells for loading samples, standards, or reagents into solid media with repeatable diameter. The set provides multiple borer sizes so the user can match well size to experiment requirements.

Typical Applications:

- Preparing wells for agar diffusion and inhibition zone tests

- Creating circular plugs in agar or soft gel materials

- Routine sample preparation in microbiology and QC laboratories

- Teaching laboratories where consistent hole size is important
