At a net weight of 0,026 kg the adapter remains practical to handle while offering robust dimensions. Delivered as 1 pc, it integrates easily into current glassware setups. Manufactured by Rettberg, the pouring spout serves organic synthesis, sample preparation and general wet-chemistry applications that demand clean, controlled dispensing. Borosilicate glass 3.3 preserves clarity and strength under typical solvent exposure and temperature cycles. The NS joint standard guarantees interchangeability with round-bottom flasks, reagent bottles and related laboratory vessels, providing a dependable transition component for efficient liquid-handling workflows.

Questions about Pouring spout, cone size 19/26, with Keck clamp
What is this article?
Pouring spout, cone size 19/26, with Keck clamp is the article on this page. Luminix Health distributes Rettberg 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.
