Description
Rotilabo®-standard ground glass joint stopper is a polyethylene (PE) plug sized for conical ground joints 10/19, finished in blue for immediate size recognition in mixed labware kits. The PE body provides a light, resilient seal for flasks, receivers and other ground-neck vessels when a full glass stopper is unnecessary. Supplied in packs of 10 pc(s), the stoppers suit routine stocking in teaching laboratories, preparative chemistry and general wet-lab drawers. Colour coding reduces mix-ups between joint sizes during assembly and dismantling of apparatus. The Rotilabo®-standard ground glass joint stopper from manufacturer ROTH SELECTION matches the conical joint 10/19 standard and is intended for temporary closure, storage and transport of glassware in organic, analytical and educational settings. Soft polymer contact can reduce the need for joint grease in many short-term applications while still seating firmly in the ground taper. Consistent blue marking and a multi-piece pack support efficient organisation of stoppers and clamps alongside other laboratory glass consumables.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-standard ground glass joint, stoppers, PE, blue, conical joint 10/19
What is this article?
Rotilabo®-standard ground glass joint, stoppers, PE, blue, conical joint 10/19 is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
