DryFast Ultra 2-Torr chemical-duty diaphragm vacuum pumps, models 2021 and 2031, are oil-less, 2-stage pumps designed to strip solvents. With respective pumping capacities of 22 and 32 L/min, models 2021 and 2031 are rated for pressure to 29.8 in. Hg and generate flow and vacuum level needed to handle high boiling point solvents (less than 160°C). They utilize corrosion-resistant PTFE on all wetted surfaces and do not require cold traps to operate.
