Description
Cross double bosshead, aluminium alloy, d=27 mm with wing screw is a laboratory clamp fitting for building and adjusting rod and stand assemblies. It provides a 180° plus 90° angle layout so rods can be fixed both in line and at right angles within the same connector. The bore diameter and greatest clamping span are 27 mm, matching common laboratory scaffolding rods, while the M10 thread and wing screw allow firm, tool-free tightening and quick repositioning during setup changes. Made from aluminium alloy, the bosshead keeps mass low yet remains mechanically stable for routine apparatus frames; the stated weight is 0,32 kg. This cross double bosshead from manufacturer Bochem is intended for chemistry, biology and teaching laboratories that rely on modular retort stands, frames and multi-rod constructions. Supplied as one piece, it supports flexible orientation of glassware holders, clamps and accessories without adding unnecessary bulk. The aluminium construction offers comfortable handling and corrosion resistance under typical dry laboratory conditions, making the fitting a practical choice for everyday scaffolding work on benches and teaching stations.

Questions about Bosshead, alu d=27mm, Thumb screw
What is this article?
Bosshead, alu d=27mm, Thumb screw is the article on this page. Luminix Health distributes Bochem for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Matériel de laboratoire.
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.
