flat seal 57.5 x 48 x 2 mm viton for bowls P-7 pl

Made of Viton 57.5 x 48 x 2 mm, for all grinding bowls premium line 80 ml, 45 ml, 20 ml volume. Due to 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. All grinding bowls for the Planetary Micro Mill PULVERISETTE 7 premium line are delivered - as a standard – with a silicone seal ring. When grinding in solvents or dry grinding of slightly caustic samples, we recommend our seal rings made of Viton, because they have a much higher chemical resistance. more
