Solution Preparation

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.

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.

accomplishes this by automatically preparing samples for liquid chromatography, gas chromatography, spectroscopy, viscosity,

NMR and other analyses.

1Sample 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

2Time 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

3Typical 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

4Up to eight different solvents can be dispensed with zero cross contamination.

Features and benefits

5Ordinary, disposable sample bottles can be used to prepare the solution directly. The expense and labor of using volumetric glassware is eliminated. Eliminates cleaning and breakageof expensive volumetric glassware.

Features and benefits

6Eliminates operator-to-operator variability.

Features and benefits

7Provides ISO and GLP documentation.

Features and benefits

8Decreases exposure solvents.

Features and benefits

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