Double bossheads, square, Laboral, d=12-13×16 mm are laboratory clamp fittings designed to join two rods or stands at a fixed right angle in bench set-ups. Each unit provides two square sockets sized for 12–13 mm and 16 mm diameters, enabling secure cross connections between common laboratory rods, retort stands and support frames. The geometry is a classic 90° double bosshead (cross clamp) configuration, suited to building rigid frameworks for glassware, sensors and reaction apparatus. Fastening is effected by an internal hexagon socket screw, which allows controlled tightening with a hex key and helps maintain alignment under typical laboratory loads. The component weighs 125,0 g (approximately 0,13 kg net), offering a solid yet manageable mass for routine assembly work. Supplied as a single piece, this Laboral-series fitting from manufacturer Bochem is intended for general laboratory scaffolding, teaching benches and preparative workstations where square double muffs are preferred for positive grip and straightforward orientation. Categories include double bossheads and cross clamps, supporting modular construction of stands without additional adapters when rod diameters match the stated ranges.

Questions about Bosshead squared, Laboral, d=12-13x16mm
What is this article?
Bosshead squared, Laboral, d=12-13x16mm is the article on this page. Luminix Health distributes Bochem for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Labmateriaal.
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.
