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
