With a fixed O-ring in the lid, the premium line grinding bowl is so tightly sealed that even grinding in suspension without an additional seal is absolutely smooth and problem-free.When grinding in solvents or dry grinding of slightly caustic samples, we recommend our seal rings made of Viton (Article No. 84.0341.15) because they have a much higher chemical resistance. more
