Combined Density / Refractive Index Instruments Some applications require both refractive index and density measurements on the same sample and find a combined instrument is a convenient alternative to two completely separate instruments. The advantages of a combined system are: • A shared interface reduces the overall cost of the system. • There may be less operator time needed to load and clean when the samples are low viscosity. • Many laboratories combine the density and refractive index results and use them to calculate a third parameter. Having both results exported into the same file...

2. FLOW THROUGH CONFIGURATION: DENSITY METER AND REFRACTOMETER OPTICS MODULE WITH MANUAL SAMPLE INJECTION DESCRIPTION This system is similar to the basic configuration but uses the DP (Dual Purpose) optics module to allow a single load between the Refractometer and Density Meter. Utilizing a syringe users can load both instruments simultaneously (see Figure A) or remove the DP Presser Cover and use both instruments in manual mode with two separate sample loads (see Figure B).

3. FLOW THROUGH CONFIGURATION WITH PERI PUMP: DENSITY METER, REFRACTOMETER OPTICS MODULE WITH PERISTALTIC PUMP SAMPLING SYSTEM DESCRIPTION A Peristaltic Pump draws the sample into both the Refractometer and Density Meter. The user drops a sipper tube into the sample and starts the Peri Pump from the display. The Peristaltic Pump draws the sample through both instruments and then measures. The measured sample is then displaced by the following sample. Sipper tube inside bottle Peristaltic Pump WHO SHOULD CONSIDER THIS SYSTEM? • Laboratories working with low viscosity samples such as...
