Sample hydrolysis and digestion vessels
For the digestion of small sample volumes up to 0.5 g in microwave ovens. Made of isostatically pressed, high-grade PTFE (TFM). The chemical resistance and usual PTFE properties remain unchanged. TFM is a modified PTFE by Hoechst and contains thermoplastic elements. This gives rise to a homogeneous, non-porous surface. Contaminating residues from earlier digestions are therefore avoided. Resists pressure deformation (to max. 25 bar) and temperature (max. 160 °C). An accessory burst-proof, sealing membrane prevents loss of volatile compounds and provides safety against overpressure. Optional digestion vessels with interchangeable inserts (internal liners) enable precise weighing-in (in most cases the complete vessels would be too heavy for balances). In addition, different digestion processes can be carried out in only one basic vessel by using several inserts.
Sealing and Rupture Membranes, PFA, PTFE
1 set consisting of 10 sealing membranes made of PFA and 10 rupture membranes made of PTFE, for digestion vessels.
