Beschrijving
Double bosshead 190° aluminium chrome-plated is a laboratory clamp connector that joins two rods at a fixed 190° angle for slightly offset support geometries. The chrome-plated aluminium body combines corrosion resistance with low mass, while the screw clamping mechanism uses a plastic head for comfortable, tool-free tightening. Independent clamping spans of 20 mm and 30 mm accommodate mixed rod diameters commonly found on retort stands and scaffolding frames. Offered as one piece with a net weight of 0,3 kg, the fitting is easy to reposition during apparatus changes yet holds securely under typical glassware loads. Teaching labs, analytical benches and pilot-scale set-ups benefit from the open 190° layout when vessels or condensers must sit just off the main vertical axis. This component from manufacturer Witeg integrates with standard laboratory rods and bossheads, supporting tidy multi-level assemblies without bulky adapters. The durable chrome finish resists fingerprints and cleaning agents used in routine lab maintenance, helping the connector retain a professional appearance through repeated use across student practicals and research workflows.

Questions about Bosshead double
What is this article?
Bosshead double is the article on this page. Luminix Health distributes Witeg 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.
