Description

DuoSeal high vacuum pump Model 1400 is effective for drying using large manifolds (Shlenk lines). 25 lpm flow rate enables thorough drying while providing sufficient cold trap residence time to allow solvents to condense. With ultimate vacuum <0.001 torr, Model 1400 is also suitable for many concentrating, drying, and degassing operations as well as rotary evaporation of low-volatility solvents. Belt-drive design with low pump rpm and large oil capacity contribute to DuoSeal’s reputation for durability.
