Description
Square double bossheads in 18/10 steel are robust laboratory clamps for securing rods and apparatus at a fixed 90° angle. Each unit accepts two rods with diameters of 12–13 mm × 12–13 mm and is tightened with an integrated hexagon socket screw for a firm, repeatable hold on retort stands and scaffolding. Manufactured from stainless steel, the square body provides stable contact faces and reliable alignment during set-ups that demand rigidity. The component weighs 99,0 g and is supplied as a single piece, making it straightforward to stock and replace in teaching and research laboratories. An optional 360° connecting rod (d=12 mm) from manufacturer Bochem can link two of these bossheads when multi-axis arrangements are required. Typical uses include mounting condensers, funnels, probes and other glassware or sensors on standard laboratory frames where corrosion resistance and mechanical strength matter. The compact square design keeps the clamp profile neat while still delivering secure dual-rod fixation for everyday bench and fume-hood work.

Questions about Bosshead squared, 18/10 Steel, d=12-13x12-13mm
What is this article?
Bosshead squared, 18/10 Steel, d=12-13x12-13mm is the article on this page. Luminix Health distributes Bochem for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Labware.
A bosshead grips the rod. A clamp grips the flask or the condenser, usually through two jaws with cork or vinyl faces. Three-finger and two-finger clamps hold different shapes. The jaw opening is the specification.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
