We typically have used and reconditioned pumps in stock from leading manufacturers like Cole-Palmer and Watson/Marlow.
For more mobile phase flexibility in any ultrahigh speed and ultrahigh resolution application, the Thermo Scientific Dionex Ultimate HPG-3400RS Rapid Separation Binary Pump offers more solvent capability. With an unrivaled flow-pressure footprint, the RSLC pump is the most flexible binary UHPLC pump available. The UltiMate 3000 Binary RS pumps are capable of providing true ballistic gradients with excellent retention time precision. Together with gradient delay volumes down to 35µL, the binary pump is the first choice for any ultrahigh speed application in LC or LC/MS.
Ensure stable baselines and consistent detector performance. The Dionex SRD-3x00 Solvent Racks Solvent Racks with Degassers for UltiMate 3000 Pumps incorporate a low-volume (670µL), chemically-inert degasser with two, four, or six channels, respectively.The SRD-3400 Solvent Rack with Degasser supports nano and capillary flow
Ensure stable baselines and consistent detector performance. The Solvent Racks Solvent Racks with Degassers for UltiMate 3000 Pumps (SRD-3200, -3400, and -3600) incorporate a low-volume (670µL), chemically-inert degasser with two, four, or six channels, respectively.
The KNF LABOPORT N840.3FTP two-stage diaphragm vacuum pump is suitable for use with concentrators, rotary evaporators, and distillation equipment (sold separately). The pump has a 34 liters per minute (LPM) free air capacity with vacuum to 8 Torr and its polytetrafluoroethylene (PTFE) air flow path is corrosion resistant. The oil-free diaphragm pump allows operation without oil misting and contaminated oil disposal. The pump accepts 115V, 60 Hz input power.
KNF Neuberger, a division of KNF Group, manufactures diaphragm pumps and systems for gases, vapors, and liquids for laboratory and manufacturing applications. The company, founded in 1977, is headquartered in Trenton, NJ.
