The Soluprep II solution preparation
system 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. 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-toweight,
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 compensates
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.

Ordering Information
The SoluPrep consists of a pump drive module having from one to eight pumps installed (please specify the
number of pumps), the SoluPrep Operating Program, interface cables, power cord and instruction manual.
We recommended that each pump used in a system be dedicated to pumping a single solvent.
