Description
Cross double bosshead, malleable cast iron, DIN 12895, D=16,5 mm is a laboratory clamp fitting for secure multi-axis mounting of rods and apparatus. The chrome-plated malleable cast iron body provides a rigid 90° plus 180° geometry with a clamping diameter of 16,5 mm, matching the greatest span stated for this model. An M8 thread and an 18/10 steel safety screw lock assemblies firmly in place on stands and frameworks. Weighing 170 g, the compact cross double bosshead is suited to everyday set-ups in chemistry, biology and general laboratory work where stable, corrosion-resistant joints are needed. Manufactured by Bochem to DIN 12895, it integrates cleanly with standard laboratory scaffolding and retort systems. The chrome finish supports easy cleaning and long service life under typical bench conditions. Supplied as a single piece, it is a practical connector for building or extending apparatus frameworks that require both right-angle and in-line clamping options in one component.

Questions about Bosshead malleable cast iron, varnished, DIN 12895, D=16,5mm
What is this article?
Bosshead malleable cast iron, varnished, DIN 12895, D=16,5mm 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.
