Description:
*A cork borer, often used in a chemistry or biology laboratory, is a metal tool for cutting a hole in a cork or rubber stopper to insert glass tubing. Cork borers usually come in a set of nested sizes along with a solid pin for pushing the removed cork (or rubber) out of the borer. The individual borer is a hollow tube, tapered at the edge, generally with some kind of handle at the other end.
*A separate device is a cork borer sharpener used to hone the cutting edge to more easily slice the cork.
*Cork borers are also used to take samples from living trees, for tree ring analysis (dendrochronology), and for taking samples for experiments when a constant diameter is required, e.g. When testing the water potential of a potato, a cork borer is used to maintain a constant surface area.
*Cork borer is also used to punch holes on an agar plate, to perform Well Diffusion assays in microbiology to study Bioactivity.
