Graphite-block digesters.
In short: Graphite-block digesters use high-purity graphite conduction heating for aggressive acid digestion. The S series runs 20 or 36 samples per batch from ambient to 450 °C with ±1 °C temperature stability and two timing modes; the Gr series (Gr08, Gr20) reaches 450 °C.

How to choose.
- S20 / S36 — 20 or 36 positions, ±1 °C stability, two timing modes; the S36 is the high-capacity hotblock.
- Gr08 / Gr20 — compact graphite blocks up to 450 °C for smaller batches.
- Why graphite — high-purity graphite conduction heating for aggressive acid digestion work.
