You can watch the sample progress through the U-Tube and monitor for bubbles. Need a closer look? View at 2X, 6X or 10X magnification. When your measurement is complete simply flush the U-Tube with your choice of solvent and use the convenient air tube to dry the U-Tube. Who Should Use this System? Laboratories who make only a few measurements per day. Users who wish to use very small amounts of sample – Only 1ml of sample is required. Optional Peristaltic Pump Refractometer Combining a Peristaltic Pump with a Rudolph Density Meter makes sample loading and cleaning faster and more convenient. A Peristaltic Pump draws the Optional sample into the Density Meter and could also load a Peristaltic Pump Refractometer. The user drops a tube into the sample and starts the Peri Pump from the DDM display. The Peristaltic Pump draws the sample through one or two instruments and then measures. The measured sample is displaced to waste by the following sample. Who Should Use this System? Laboratories working with low viscosity samples such as beverages. Users who don’t mind utilizing 50 ml of sample for a measurement. A large amount of sample is needed to ensure all of the previous sample is displaced with the new sample.

Samples are easily poured right into the AutoFillTM sample well without having to come in contact with the sample; simply pour it in. From there the lid is closed and the sample is advanced to the U-Tube with the push of a button on the DDM touch screen. To clean, open the lid and pour in the solvent of your choice. Close the sample well lid again, press a button and the solvent is flushed through the U-Tube and air drying is automatically started. Who Should Use this System? Users who want to make many measurements each day and want an easy to load Density Meter with an equally easy cleaning routine. Laboratories who do not want to come in contact with caustic acids or bases. AutoFillTM allows you to easily pour directly into the sample well.

Using Rudolph’s ECS Auto Sampler is simple; the user brings the sample to the Density Meter in any container that has an opening and a sample volume of 3-4ml. A test tube or beaker is commonly used in a lab and a can or bottle is more common in industrial environments. The operator presses the fill button, waits a few seconds while the sample is drawn from the sample vessel, and the Density Meter U-Tube is filled with sample. From that point the operation is completely automatic. The sample is measured and the data is recorded. Depending on how the system is configured the data may also be printed, saved to an Excel file, stored in the instrument, or transferred to a LIMS system. Once measurement is complete, the sample is blown to a waste storage vessel using the built in air pump. The measuring cell is flushed with a solvent of the user’s choice, flushed again with a second solvent such as acetone or alcohol that is fast drying and then blown with air to completely dry the system. The dry and rinse times are user programmable. Utilizing a WindowsTM interface the operator is able to select and adjust both rinse and air drying times for each unique sample. Who Should Use this System? Laboratories looking for a faster and semi-automatic sample loading and cleaning solution. Laboratories that want to decant from their own vessels and sampling containers. Laboratories working with acids, bases, and caustic samples.
