Beschreibung
Septum stopper for NS 29/32 with fold-over rim, silicone is a laboratory closure designed for standard ground joints of NS 29/32 size. Manufactured from silicone, it features a fold-over rim that turns down over the joint collar to improve mechanical retention and sealing performance on glassware. The elastic silicone body conforms to the ground surface, enabling reliable temporary closure of flasks and reaction vessels while still permitting needle penetration for additions or sampling. Each pack contains 5 pieces, offering a practical quantity for routine laboratory stocking and replacement. These septum stoppers from manufacturer Rettberg are listed under the product type Septumstopfen and carry a net weight of 0,02 kg. Originating from France, they suit everyday organic synthesis, distillation and sample-preparation work where NS 29/32 joints must be sealed quickly and securely. The fold-over rim distinguishes the design from simple plug septa, reducing the chance of accidental displacement during handling. Compatible with standard taper glassware, the stoppers provide a straightforward sealing solution for chemistry and life-science laboratories that require flexible, reusable joint closures without additional clamping hardware.
