Unmatched Versatility, Traceability, Compliance and Flexibility For Highly Regulated Labs, Full 21 CFR Part 11 Instrument Level Compliance The United States Food and Drug Administration 21 CFR Part 11 regulation establishes the FDA’s requirements for electronic records and electronic signatures (ERES) to be trustworthy, reliable, and essentially equivalent to paper records and handwritten signatures. The Rudolph Density Meter user interface software’s 21 CFR Part 11 features fully supports and exceeds the requirements of 21CFR Part 11. Available in embedded and PC versions. The Rudolph...

Unmatched Versatility, Traceability, Compliance and Flexibility NIST Traceable Calibration Standards Rudolph knows how important it is to calibrate with Traceable Standards and therefore, we include either a NIST or other National Physical Laboratory (NPL) traceable standard in the accessories provided with your density meter. The Rudolph DDM Series Density Meter includes all the accessories for immediate use*: • Quick Start Guide • Traceable Standard • IQOQPQ Documentation • Luer Syringes • Rinse/Sample Waste Container • User Manual • Filling Nozzles • Connecting Fittings & Tubing •...

Choose the Sample Load Option Solution for Your Application Vertical Load • Sample injection is done vertically against gravity reducing air bubbles. Suitable for left and right handed operators as opposed to manual horizontal injection. Plunger is easier to push with all samples and there is more control over the syringe than with Horizontal Load. • Gives the ability to apply more pressure to the syringe when injecting viscous samples without harming operators. • Much easier cleaning. When a measurement is complete and the syringe is removed, gravity will force the sample down and into the...

Choose the Sample Load Option Solution for Your Application LoadAssistTM • Great option as there are two ways to inject a sample: by manual vertical injection or having the PeriPump pull the syringe down for you. • Ideal for pulling the rinse solutions automatically into the system thus making the rinsing part of the operation much easier and independent. • Pressure mode available for carbonated samples. • Benefits customers that have multiple inexperienced users as the PeriPump will automatically inject the sample the same way every time. • No change in instrument’s performance when...

Sample handling options for high throughput laboratories Peristaltic Pump Combining a Peristaltic Pump with a Rudolph Density Meter makes sample loading and cleaning faster and more convenient. A Peristaltic Pump draws the sample into the Density Meter and could also load a second instrument such as a Refractometer. The user drops a tube into the sample and starts the Peri Pump from the Density Meter display. The Peristaltic Pump draws the sample through one or two instruments and then measures automatically. The measured sample is displaced to waste by the following sample. Who Should Use...

Sample handling options for high throughput laboratories Automate your Laboratory with a Rudolph Autoflex® R837 or R835 Automation System The DDM Series Density meters can be combined with various Rudolph Automation Systems and Sample Handling Accessories such as: Peristaltic Pump, ECS (Easy Clean System), Autofill®, Autoflex® R835 and Autoflex® R837 AutoSampler. The Rudolph Research R837 AutoFlex® is perfect for high throughput laboratories looking to increase productivity. The AutoFlex® R837 Sampler Features : • Customizable bottle size, Test Tube size such as: Boston Rounds:1oz, ½ oz,...

Combine a Density Meter with a Refractometer for additional Measurements Test obscured Alcohol samples with Rudolph’s AlcoTest®-RI System. Long measurement needle and Peristaltic Pump make bottle measurement easy Obscured Alcohol samples are any solutions containing alcohol, water plus anything else such as flavoring or barrel aging. This includes beer, wines, flavored spirits and many barrel aged rums, whiskeys, and Bourbons. The AlcoTest®-RI measures the sample by calculating the density of the sample and then correcting for the obscuration using refractive index. The user can measure %...
