Product Description
Keep volatile reagents, standards and prepared solutions sealed between uses with stoppers made to seat in ground-glass flask necks. A properly matched ground joint closes off the opening without rubber or plastic touching the contents, which helps protect sample purity and limits evaporation during storage on the bench or in a cabinet.
This listing is for catalog number 3085: Ground Glass Flask Stoppers, Clear, No. 22, Pack of 6. Each stopper is made of glass with a ground, tapered sealing surface that mates with a flask neck of the corresponding size. The family covers stopper numbers from No. 9 up to No. 27, so you can match the stopper to volumetric flasks, reagent bottles and other ground-neck glassware already in use. Stoppers are packed in sets of six for replacing lost or chipped pieces. LIGHT LABS ships genuine Heathrow Scientific products with knowledgeable support from our Englewood, Colorado team.
Key Features

- Multiple stopper numbers – Sizes from No. 9 to No. 27 cover a broad range of common flask necks.
- Reusable – Glass stoppers can be washed and returned to service repeatedly.
- Six-piece packs – Convenient quantity for stocking spares and replacing lost stoppers.
