Description
Stand clamp with bosshead 20-40 mm is a robust laboratory retort clamp designed for secure holding of apparatus on stands. Fabricated from zinc die-cast and finished with a durable powder coating, it offers reliable mechanical stability in everyday lab setups. The adjustable jaws provide a clamping range from 20 mm to 40 mm, making the unit suitable for a variety of glassware diameters and electrode holders. A cork insert cushions the contact surface, protecting delicate vessels while maintaining a firm grip. With a net weight of 0,190 kg, the clamp remains easy to position yet solid enough for repeated use. This model from manufacturer Usbeck integrates a bosshead for direct attachment to standard retort rods, streamlining assembly of distillation, titration or filtration arrangements. Ideal for general chemistry, teaching laboratories and routine analytical work, it combines straightforward operation with long-lasting construction. The powder-coated surface resists corrosion and cleaning agents commonly encountered in wet-chemistry environments, ensuring consistent performance over extended periods.

Questions about Clamp 40 mm with Bosshead
What is this article?
Clamp 40 mm with Bosshead is the article on this page. Luminix Health distributes Usbeck 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.
