Description
Ground joint clips NS 19/26, blue are laboratory accessories for securing standard conical ground-glass joints in assembled glassware. Made from polyoxymethylene (POM) plastic, they deliver a firm mechanical hold on NS 19/26 joints used in distillation, reflux, synthesis and general preparative work. The polymer body combines dimensional stability with everyday chemical resistance and is rated for a maximum operating temperature of 150 °C. Colour coding in blue supports rapid visual identification of joint size when several clip formats are kept side by side on the bench. Packaged as 10 pc(s), the set is convenient for equipping multiple setups or replenishing teaching and research laboratories. These clips from manufacturer Marienfeld help keep ground joints aligned and connected without wire springs or tape, simplifying apparatus assembly and reducing the chance of accidental disconnection during heating or stirring. Suitable for standard laboratory glassware with NS 19/26 conical joints, they are a practical consumable for organic chemistry, analytical sample preparation and routine quality-control workflows where reliable joint retention is required.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Clamps for standard ground joints NS 19/26, blue
What is this article?
Clamps for standard ground joints NS 19/26, blue is the article on this page. Luminix Health distributes Marienfeld 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.
