For High Accuracy Applications The DDM Series of Automatic Density Meters Rudolph Research Analytical, serving its customers with Integrity, Quality, and Innovation for over fifty years.

The Simplicity of Touch Screen Measur Oscillating U-Tube with Viscosity Correction and Reference Oscillator Rudolph DDM Density meters utilize an oscillating U-tube with full range viscosity correction and reference oscillator that allows for long term calibration stability and measurement at all temperatures with a single calibration. (Patent # 7,735,353) Full Feature VideoView™ with Automatic Scanning of Entire U-Tube Rudolph’s exclusive VideoView is protected under Patent #7,437,909 and provides superior high resolution visual bubble detection within your sample with live on-screen video viewing....

rement with the Flexibility of Windows cGMP/GLP Calibration • alibrate the Rudolph DDM Density Meter with 2 or 3 NIST Traceable C Standards – calibrating with merely air and water appears inconsistent with cGMP/GLP compliance regulations • an print out complete method configuration, communication settings, C as well as calibration verification and calibration adjustment data/history • easured values can be shown continuously as temperature stability is M being reached or, at the discretion of the user, measured values will only be displayed once the measurement is complete • nlimited number of...

Versatility, Traceability, C 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 DDM Density Meter user interface software’s 21 CFR11 features fully support the requirements of 21CFR Part 11. The Rudolph DDM Density Meter’s 21 CFR Part 11 software module is easily enabled through the user friendly...

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) standard in the accessories provided with your density meter. The Rudolph DDM Density Meter includes all the accessories for immediate use: • Traceable Standard • Quick Start Guide • Luer Syringes • IQOQPQ Documentation • User Manual • Rinse/Sample Waste Container • Filling Nozzles • Connecting Fittings & Tubing Flexible Method Management Customized Methods: Factory installed...

Choose the sample handling Syringe Injection Samples can be easily loaded in the DDM series Density Meter by directly injecting your sample into the inlet port of the DDM. 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...

solution for your application Rudolph DDM with AutoFillTM AutoFillTM was developed by listening to customers who wanted an easier method of sample loading that they could decant right from their existing containers. 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...

Sample handling options for h Rudolph DDM with the Rudolph Easy Clean System (ECS) The Rudolph ECS sampling system is an excellent choice if you need to significantly automate your sample loading and cleaning. 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...

AlcoTest-RI-J209 AlcoTest-RI-J209 Alcohol Production Test Solution By Measuring Specific Gravity and Refractive Index the alcohol % by vol/vol can be determined for many products. This is a fast, single sample load solution for the Alcopops, Wine and Beer industries. The process of pre-distilling samples to remove the alcohol and adding back distilled water to replace any solids is eliminated. Simply load a sample into the system, the system measures the sample and using the AlcoTest software calculates the alcohol %. AlcoTest-RI-J209 is ideal for • High volume producers of Alcopops products...
