TurboVap LV – Building on Solid Foundations | Page 1 ® Building on Solid Foundations TurboVap is a second generation product which builds on the solid foundations of the historic TurboVap product line and incorporates many new customer driven features. It still features the highly efficient patented gas vortex shearing technology, which is synonymous with the TurboVap brand. ® This modern design features many new enhancements, including a well-lit glass tank for much greater visibility, removable/replaceable nozzles on the lid, on- the- fly nozzle adjustment, easily exchangeable manifolds to extend functionality, programmable evaporation flow gradients, easy access drain port and user friendly touch screen interface. The system can be vented from the bench or placed in a fume hood. Because the footprint is noticeably smaller on the modern unit, less space is required. A novel and innovative feature of the new TurboVap family is the Multi Rack that can be fully adjusted for a range of tube/ vial sizes. By using the series of Multi Racks, the TurboVap LV will accommodate tube/vial sizes from 1.5 mL up to 60 mL. Two versions of the 48 position rack are available to accomodate most common glassware sizes. When used in the 24 position mode, the Multi Rack will accommodate 24 x I-Chem/ASE/EPA vials, 24 x 50 mL centrifuge tubes/Greiner or 24 x TurboVap II, 50 mL, 0.5 or 1.0 mL End Point Tubes. Faster Evaporation Improved Recovery In addition to the many user-friendly improvements, the new TurboVap LV outperforms its predecessor as well, providing faster Evaporation, higher analyte recoveriesand lower RSD’s. (Figures 1–3). The new Turbovap LV is design so that it can be easily and quickly converted between the functionality of the traditional LV and II instruments, as well as accomodate Extrahera Automation compatible racks. For demanding applications involving the use of aggressive acids and bases we offer an upgraded version of the standard instrument which features a PTFE coated manifold and treated nozzles. This system is resistant to the following substances. »» Trifluoroacetic acid (TFA) 2% »» Trichloroacetic acid (TCA) 2% »» Formic acid 5% »» Acetic acid 5% »» Butyric acid 5% »» Phosphoric acid 5% »» Hydrochloric acid 0.1 M »» Nitric acid 0.1 M »» Ammonium Hydroxide
