FAQ
- Rotary vane or water-circulating? Water-circulating for rotovap & filtration (oil-free); rotary vane for deeper vacuum in distillation.
- Can it handle corrosive vapors? Yes, choose the anti-corrosion or full-PTFE SHZ-DIII version.
- Is maintenance complicated? Water-circulating pumps are nearly maintenance-free; rotary vane pumps need periodic oil change.
- What is the warranty? 12 months with lifetime spare parts supply.
