Opis

Black rubber stopper with a bottom diameter of 56.00 mm, top diameter of 65.00 mm, and height of 45 mm is designed for sealing large laboratory vessels such as wide-neck flasks, containers, or reactors.

Despite the mention of “Materiał: szkło Boro 3.3” (borosilicate glass), this appears to refer to the intended vessel material, not the stopper itself. The stopper is made of durable black rubber, suitable for use with borosilicate glassware (e.g., Boro 3.3) due to its chemical compatibility, thermal resistance, and tight sealing properties.

Key features:
– Large, tapered profile for sealing wide glass necks
– Excellent resistance to water-based solutions, mild chemicals, and laboratory cleaning agents
– High elasticity for repeated use without deformation
– Secure fit in vessels made from borosilicate 3.3 glass, commonly used in chemical and analytical labs

Ideal for bulk storage containers, reflux systems, or custom glassware setups requiring a robust and stable seal.
