Fritsch® flat gasket 57,5x46,5x2 silicone f. Agate cup P-7 pl

made of silicone 57.5 x 46.5 x 2 mm for agate grinding bowls premium line 80 ml, 45 ml, 20 ml volume. Due to a fixed O-ring in the lid, the premium line grinding bowls close so tightly that grinding in suspension is also possible without any problems without an additional seal. For all other grinding bowls premium line 80 ml, 45 ml, 20 ml volume, please order the replacement seal 84.0342.15 made of silicone 57.5 x 48 x 2 mm. For grinding with solvents or for dry grinding of lightly corrosive samples, we recommend our Viton seals (article no. 84.0341.15), as these have a much higher chemical resistance.
