Period

Canada

This item was used at the Centre for Addiction and Mental Health at the University of Toronto. It is typical of an item found in many labs across Canada.

Function

A device used in a laboratory to drill either cork or rubber stoppers for flasks, bottles etc.

Technical

The ability to bore a hole through a cork or through a stopper has existed as long as rubber stoppers have not been sold with holes through the middle. Most cork borers are small devices which involve twisting a a sharpened brass cylinder into the cork by hand. This device does the same but uses a hand-crank to deliver more force. Its cost is such that a lab would own one if cork boring was required on a regular basis. This example has a heavy base with holes so that it might be attached to a lab bench. The drilling shaft is adjustable. There is a metal rack attached to the shaft to hold eight drill bits.
