Laboratory water distiller Puridest PD 4 G

automaticsimplebenchtop

Product overview
The Puridest PD 4 G is a fully automatic glass water still for single distillation, suitable for bench or wall mounting. It delivers up to 4 L/h of ultra‑pure water (conductivity stage 1 / 25 °C: 2.2 µS/cm) and does not require specialist commissioning or complex maintenance. Distillation starts at the push of a button and the process remains visible via a removable, non‑fogging front screen.
