It is an ideal choice for vacuum distillation, concentration, drying and degassing applications. The limit pressure of < 0.001 Torr provides excellent drying performance for the most difficult samples. Low pump speed reduces wear and minimizes temperature to reduce oil degradation. Large amount of oil dilutes pollutants and prolongs service life.
