Heidolph 5s clamp (silicone band)

To fix round flasks, this 5-piece clamp can be attached around the StarFish holding rod. The clamp consists of five telescopic arms that can be extended individually. They are equipped with heat-resistant silicone bands. Due to their elasticity, they are suitable for securely attaching the round flasks - from 15 to 70 mm in diameter - to the setup. The silicone bands can be purchased separately if required.
