The Soluprep II accomplishes this by automatically preparing samples for liquid chromatography, gas chromatography, spectroscopy, viscosity, NMR and other analyses. The Soluprep II System improves laboratory sample-solution preparation by offering the following advantages.Sample solutions can be routinely prepared on a weight-to-• weight, Normal, Molal or Molar basis to an accuracy of 0.02%, two parts in 10,000).Time is saved because only the approximate amount of the • sample needs to be added to the sample. The computer com-pensates by adding the exact amount of solvent.Typical solution preparation time is less than 2 minutes. If your lab • analyzes 50-100 samples per day the labor savings can rapidly recover the cost of investment.Up to eight different solvents can be dispensed with zero cross • contamination.Ordinary, disposable sample bottles can be used to prepare • the solution directly. The expense and labor of using volumetric glassware is eliminated. Eliminates cleaning and breakage of expensive volumetric glassware.Eliminates operator-to-operator variability.• Provides ISO and GLP documentation.• Decreases exposure to solvents.• Samples solutions can be easily prepared with mixtures of • solvents. This eliminates the labor and waste associated with premixing solvents.A self-adhesive label(s) for the prepared solution is automatically • printed for each sample. A permanent file of each sample and its preparation is stored for later recall.Virtually any solvent can be used.• Solution Preparation SystemChange in solvent density as temperature increases by 5º C.Solvent % DecreaseAcetone 0.758Acetic Acid 0.510Methanol 0.827Ethanol 0.825n-Propanol 0.503Methyl Ethyl Ketone 0.658Toluene 0.616Benzene 0.687Carbon Tetrachloride 0.401Chloroform 0.422Methylene Chloride 0.513Water 0.116Cyclohexane 0.706Dimethyl Sulfoxide 0.497TABLE 1Solution PreparationTypical solution accuracy +/- 0.02% (on 50 ml of a 1% solution)Number of methods stored 100Number of solvent pumps From one to eightPump type Pulseless, self-priming, magnetically coupled, gear pumps.
