The captured volume ofre-circulating air or nitrogencarries the solvent vapor to anintegral cold trap where it iscondensed and collected. Whenworking with high boiling solvents,such as DMF or DMSO, whichrequire more drying time thanorganic solvents, replenishing dryice in the cold trap becomesinconvenient.An optional coiled tubinginsert provides a flowing coolantarrangement from hood plumbingor a lab circulator. This capabilitymakes overnight drying of DMSOsamples easy and convenientthrough unattended continuouschilling of the cold trap. For thoseusers without chilled coolantcapability, an optional PolyScienceIP-60 Immersion Cooler is availablefrom Modular SFC.The Centrifan PE is a nomaintenance,sample-safe, andreliable companion to traditionallaboratory evaporators and forimplementing student-safe, lowcostevaporation for instructionallaboratory curricula. The closedsystem makes the Centrifan PE agood choice for harsh inorganicchemistry, cold room operations,toxic compounds, radioisotopes,flavors, fragrances, and otherchemical entities that causeproblems with vacuum andnitrogen systems.The six-vial capacity of thetypical rotor also makes theCentrifan PE a companion for FlashLC platforms, where collection ofthe compound of interest occursin the same few sample vials. Drydownof those specific fractionscan begin immediately as theFlash LC is prepared for the nextinjection. Finally, because theCentrifan PE collects all the solventvapor that it generates, it is a farmore ecologically responsible toolthan typical nitrogen blow-downsolutions.With a small 8-inch-by-12-inchfootprint and only 18 inches high,the Centrifan PE is an integratedevaporation system that needsonly a fume arm to catch residualvapors for the short times thatthe lid is open. Seven rotoroptions are available toaccommodate 20, 30, and 40 mLScintillation vials, 1.6 mL Eppendorftubes, 4 mL (1 dram) vials,16x100mm test tubes, and 1.8mLAgilent vials.The Centrifan PE PersonalEvaporator was developed byModular SFC.Visit Quasar Instruments atBooth 719.New AutomatedHomogenizer &Liquid HandlingSystemThe Omni LH96 AutomatedWorkstation combines multiplesample prep steps into oneautomated platform. The patenteddesign features multi-samplehomogenizing, liquid handling,pipetting, and sample weighing ina space-saving footprint that fitsinside most fume hoods.The unit is customizable andworks with Omni Tip plastic probeswith eliminating sample carryoverand cross-contamination. The LH96offers time savings over traditionalmanual sample prep methods,completing in minutes what usedto take hours, while minimizing thepossibility of human error betweensamples. It also saves money byeliminating the need for multipledevices.Visit Omni International atBooth 3904.Space-saving Range of Lab Equipment ApplicationsThe clinical chemistry industry hasseen tremendous advancementsin the areas of throughput,accuracy and lower operatingcosts. The fluidic engines of theseinstruments are a critical pieceof this progress. Parker PrecisionFluidics offers solutions that helpadvance this technology, offeringaccurate microfluidic control andrepeatable results in compact,lightweight components andsystems.Whether equipment is movingthe sample, reagents, bleach orwaste, Precision Fluidics valvesand pumps can solve applicationrequirements. Its waste pumpsremove processed samples andare highly inert, providing long,reliable life, while Parker valvesoffer chemical compatibility andconsistent flow and pressure.Parker’s engineers designcomponents to help save space andmaintenance costs and to maximizeperformance.
