Ground joint stopper NS 10/19 is a plastic laboratory stopper for sealing standard conical ground joints of size NS 10/19. It is made from low-density polyethylene (LDPE) and combines a lightweight PE body with an octagonal grip and a red insert plate for secure handling and clear visual identification on glassware. The stopper is intended for flasks, adapters and other apparatus fitted with matching NS 10/19 joints in general chemistry, teaching and routine sample work. Pack size is 100 pieces, with a minimum order quantity of 100 pieces, supporting economical stocking of plastic stoppers for high-throughput benches. The LDPE construction offers a flexible fit on the ground joint surface while remaining easy to insert and remove, including when gloves are worn. The octagonal head improves torque control during seating, and the red insert plate contrasts against typical laboratory glass. These Normschliff stoppers from manufacturer Marienfeld provide a practical PE alternative where a durable plastic closure is preferred for standard joint sizes.
