Description
Double bosshead, coated zinc die-cast, 90° angle is a laboratory clamp fitting for securing rods in a fixed right-angle layout on stands and frameworks. The body is powder-coated zinc die-cast with screws of powder-coated nickel-plated steel, conforming to DIN 12985 and accepting rods up to Ø 16,5 mm. The protective coatings improve surface durability and handling comfort during repeated assembly, while the 90° geometry keeps vertical and horizontal rods aligned for stable support of flasks, condensers, sensors, and related apparatus. Supplied as a single piece with a net weight of 0,117 kg, this double bosshead from manufacturer Witeg suits teaching laboratories, quality-control benches, and research stations that need a cost-effective yet sturdy connector. It pairs with standard laboratory rods and complementary clamps to build modular scaffolds for distillation, titration, sample preparation, and general apparatus mounting. The coated die-cast construction balances mechanical strength with everyday corrosion protection under normal indoor laboratory conditions. Use it wherever a standards-compliant, powder-coated 90° double bosshead is required for dependable rod-to-rod coupling in chemical, biological, or analytical workspaces.

Questions about Double sleeve coated zinc die-cast angle 90°
What is this article?
Double sleeve coated zinc die-cast angle 90° is the article on this page. Luminix Health distributes Witeg 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.
