Fritsch® Flat gasket 57,5x48x2,0 Viton f. Cup 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 bowls close so tightly that grinding in suspension is also possible without additional sealing. All grinding bowls for the planetary micro mill PULVERISETTE 7 premium line are supplied with a silicone seal as standard. For grinding with solvents or for dry grinding of slightly corrosive samples, we recommend our seals made of Viton, as these have a considerably higher chemical resistance.
