Description
Retort ring with boss head, Ø 150 mm, is a robust laboratory support accessory designed for secure mounting on stands and frameworks in everyday lab setups. Manufactured from cast iron, the ring provides a stable circular support surface for flasks, beakers and other round-bottom vessels during heating, cooling or holding operations. The integrated boss head allows direct clamping to a standard retort stand rod, enabling quick height adjustment and firm positioning without separate clamps. Supplied as a pack of two pieces from manufacturer Labbox, this configuration is practical for multi-position workstations or spare replacement use. With a diameter of 150 mm and a net weight of 0,530 kg per pack, the rings offer a solid, durable feel suited to routine chemistry, teaching laboratories and general analytical workflows. Cast-iron construction supports reliable mechanical strength under typical laboratory loads. Ideal for organising apparatus on vertical stands, the retort rings help keep glassware centred and secure while reagents are processed or reactions are observed.

Questions about Closed retort ring with bosshead, 150 mm, 2 pcs
What is this article?
Closed retort ring with bosshead, 150 mm, 2 pcs is the article on this page. Luminix Health distributes Labbox 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.
