Description
Hand cork borer set 1–3, covering 5,0–7,5 mm outer diameter, provides nickel-plated brass borers with handles for clean, controlled cutting of corks and similar stopper materials in the laboratory. Each tube has a wall thickness of 0,4 mm, supporting precise boring with minimal deformation of the workpiece. The set includes an ejector so cut plugs can be removed quickly and cleanly after use. Suitable for preparing standard cork, rubber, silicone and related stoppers, these tools from manufacturer Usbeck fit routine work in chemistry, biology and teaching laboratories where reliable hole diameters are required. The compact hand-operated design allows direct manual control of cutting depth and alignment without powered equipment. Nickel plating protects the brass body and helps maintain a smooth cutting edge under repeated use. Supplied as one complete set of sizes 1 to 3 for outer diameters from 5,0 mm to 7,5 mm, with a net weight of 0,080 kg, the kit is a practical addition to stopper and glassware preparation benches.

Questions about Cork Borer Set 1-3, 5,0 - 7,5 mm outside Ø
What is this article?
Cork Borer Set 1-3, 5,0 - 7,5 mm outside Ø is the article on this page. Luminix Health distributes Usbeck for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, 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.
