Questions about Ground-joint glass stoppers

Which NS size of ground-joint stopper?

Match the NS size in the title to the number on the joint. A different size does not seal. The joint number is on the glassware, not on this page. Glassware with those joints is in ground-joint glassware.

Hollow glass, solid glass, PTFE or PE stopper?

Read the material in the title. Hollow and solid glass stoppers are both on this shelf. Choose PTFE or PE when the title names that plastic, where a glass stopper can seize or where the liquid asks for it. Send a photo of the joint marking if the size is unclear: sales@luminixhealth.com.

Why Ground-joint glass stoppers?

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.

This shelf belongs to Stoppers, caps & closures, inside Labware. Luminix Health distributes this range for laboratory use.
