All grinding bowls for the Planetary Micro Mill PULVERISETTE 7 premium line are delivered - as a standard – with a silicone seal ring. Due to this seal ring, the lid and grinding bowl are so tightly sealed that even grinding in suspension is possible absolutely 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.
