What is the difference between Vacuubrand diaphragm pumps and rotary vane pumps for lab use?

Diaphragm pumps are oil-free, chemical-resistant, and require minimal maintenance — ideal for rotary evaporation, filtration, and gel drying with common solvents. Rotary vane pumps achieve deeper ultimate vacuum (lower mbar) needed for high-vacuum distillation, freeze-drying, or degassing of low-volatility materials. Contact us with your required vacuum depth and chemical compatibility for the right pump recommendation.
