1. Solution Preparation

2. is a solution preparation system that automatically calculates and dispenses the exact amount of solvent required to prepare a precise concentration based on the approximate mass of solute added by the operator.

3. The demand for greater accuracy from analytical instruments has prompted the automating of sample preparation based on the much more accurate solvent weight-to-sample weight basis.

4. accomplishes this by automatically preparing samples for liquid chromatography, gas chromatography, spectroscopy, viscosity, NMR and other analyses.

5. 1 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). Features and benefits

6. 2 Time is saved because only the approximate amount of the sample needs to be added to the sample. The computer compensates by adding the exact amount of solvent. Features and benefits

7. 3 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. Features and benefits

8. 4 Up to eight different solvents can be dispensed with zero cross contamination. Features and benefits

9. 5 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. Features and benefits

10. 6 Eliminates operator-to-operator variability. Features and benefits

11. 7 Provides ISO and GLP documentation. Features and benefits

12. 8 Decreases exposure solvents. Features and benefits

13. Samples solutions can be easily prepared with mixtures of solvents. This eliminates the labor and waste associated with premixing solvents. 9 Features and benefits

14. 10 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. Features and benefits

15. 11 Virtually any solvent can be used. Features and benefits

16. 1.Operator signs in and selects/edit the method. The Process

17. 3. Select the sample to prepare The Process 2. Enter the mixture data.

18. 4.The completed sample is removed and the printed sample label is affixed to the bottle. The Process You can edit the caption fields to be printed on the label.

19. The Pump Test option allows you to test the pump speed.
