Details:

Specifications for use with concentrators and rotary evaporatorsfluorinated plastics used on all wetted partssolvent resistant at boiling points under 100°cportablesystem is powered by a 1/8 hp, corrosion-resistant, ptfe pump. All wettable parts, including the diaphragm and valves are ptfe. Vacuum level regulator and built-in dial guage allow easy control of pressure to prevent sample bumping or foaming. Switchable gas ballast inhibits vapor condensation inside pump heads. An inlet separator traps ejected condensed solvent vapors. A self-cleaning purge automatically runs for two minutes at shut-down to expell unwanted residue, extending the diaphragm life. Use with rotary evaporators up to 5 l capacity. A cold trap, such as welch 1420h-14 (7893r90) is recommended when using this pump with centrifugal concentrators. Also recommended for use with vacuum ovens up to 28 l capacity.Thomas no.Welch no.Free air displacementultimate pressuretakes tubing (i.D.)Power7893q0520250134 lpm (1.2 Cfm)10 torr1/4 "115v1233k7320250334 lpm (1.2 Cfm)9 torr1/4 "230v1234x1320270132 lpm (1.1 Cfm)2 torr3/8 "115v1233k742027c0332 lpm (1.1 Cfm)2 torr3/8 "230v
