Teledyne CombiFlash RF Plus UV Flash Chromatography System**This Unit has been tested as far as we could. Has missing tubing in the fraction collector arm. Unit was powered on and sent through testing with the materials present on the unit. Has slight of cosmetic blemishes for regular use. See photos for further details.Delivers reversed phase purifications at a fraction of the cost of preparative HPLC. The system operates at pressures up to 150 psi (10.3 bar) for your separation needs. The rugged construction you have come to expect from Teledyne Isco makes this a daily workhorse for your demanding routine. The CombiFlash Rf+ improves productivity if it is used to purify synthetic compounds, natural products, peptides or polymers. The system is compatible with both normal and reversed phase purification conditions.UV spectra display in real-time and post runRFID (Radio Frequency Identification) technology automates setting the parameters for purification runs and fraction collectionBuilt in active solvent and waste management prevents columns from drying and waste overfillsRapid column air purge prevents solvent from being discarded with the used columnEasy scale up with built in method scalingHas internal fraction collectorThe TLC to Gradient calculator automatically determines optimal separation parameters while minimizing run time. UV and UV-Vis detection: Variable UV 200 - 400 nm standard. Variable UV-Vis 200 - 800 nm option Number of solvents: Binary gradient with any two of four solvents; a third solvent can be used to add modifier at a fixed percentage Programmable gradients: Linear, step, isocratic Sample injections: Auto-inject with 6-position automated motorized sample loading valve; self-cleans at end of run; solid or liquid injection.User interface: 10.4 touch screen. Built-in networking allows you to connect to the CombiFlash Rf+ to monitor and remotely control your experiment, analyze data, and print to network printers.SpecificationsFlow Rate Range: 1 - 200 mL/minMaximum Pressure: 200 psi (14 bar)Detection: UV (UV-Vis optional) + ELSDSpray Chamber Temperature: Ambient to 120 CDrift Tube Temperature: 10 - 70 CGas Requirements: 65 psi (4.6 BAR) 5 psi (0.3 BAR) Nitrogen or other inert gasDimensions (H x W x D): 24 x 14.1 x 17 in(61.0 x 35.8 x 43.2 cm)Additional Prep Fees May Apply
