Questions about Bosshead, Fisher type, for rod diameters from 9 to 16 mm, 4 pcs
What is this article?
Bosshead, Fisher type, for rod diameters from 9 to 16 mm, 4 pcs is the article on this page. Luminix Health distributes Labbox 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.
