Description
Hand cork borer set 1-12, covering outer diameters from 5,0 to 18,75 mm, is a complete laboratory tool kit for cutting clean, round holes in cork and related stopper materials. The borers are made of nickel-plated brass with a tube wall thickness of 0,4 mm, giving a rigid cutting edge suited to repeated stopper preparation. Handles and an ejector support controlled boring and straightforward removal of the cut core after each use. Supplied as the full numbered range from size 1 through 12, the set matches common cork and stopper diameters used in chemistry, biology and teaching laboratories. Nickel-plated brass construction from manufacturer Usbeck offers corrosion resistance under typical bench conditions and is easy to wipe clean between tasks. The complete set has a net weight of 0,400 kg, so it remains compact for drawer or bench storage while staying robust enough for daily laboratory work. Typical uses include preparing cork stoppers, fitting closures and general vessel preparation where precise circular openings are required.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cork Borer Set 1-12, 5,0 - 18,75 mm outside Ø
What is this article?
Cork Borer Set 1-12, 5,0 - 18,75 mm outside Ø is the article on this page. Luminix Health distributes Usbeck for laboratory use. It sits in Bouchons en caoutchouc & silicone, inside Bouchons, capuchons & fermetures, in Matériel de laboratoire.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
