€Checking of raw materials and product release
€21CFR11 Compliance; Electronic Signature and Secure Data Storage

BEVERAGE

€Measure both alcoholic and nonalcoholic beverages with easy bubble detection using VideoView€
€Direct and accurate means of €Brix determination, €Plato, Extract, % Solids
€Use apparent density function for proper filling volume monitoring

Flexible Method Management

Factory installed density measurement methods allow for immediate selection of the correct method to match the most common applications.


For unique measurement applications, create a sample method using an unlimited number of Concentration Tables, Formulas, and Polynomials to match the density measurement methods used in your laboratory. A few customized sample methods shown below:

€Concentration D2O - Heavy Water
€Baum€ of Hydrochloric Acid
€Normality of Sulfuric Acid
€Molecular Weight of Polymer
€Drug to Propellant Ratio
€Lead Content
€ppm Gold in Acid
€% Toluene in Heptane
€Fat in Lubricant
€Mole Fraction of Methanol
€% HNO3
€Monomer Solutions
€Potassium Permanganate
€Hydrogen Peroxide
€Molar Solutions of EDTA
€SG of Urine
€Sweeteners
€Sodium Hydroxide


Setting up your custom method is as simple as filling out a few screens like the one below:

VideoView€ Bubble Detection

No more straining to see small difficult-to-detect air bubbles in your sample with live on-screen video viewing. On-screen bubble detection is made possible utilizing Rudolph's exclusive VideoViewTM (patent pending) with 10X magnification.

Full 21CFR Part 11 Instrument Level Compliance

The DDM 2911 and DDM 2910's 21CFR Part 11 software module is easily enabled through the user friendly touch screen. This module gives you full compliance with:

€Electronic Signature
€Access Levels
€Internal write protected storage
€Unique passwords
€Write protected documents sent directly to server

Oscillating U-Tube with Viscosity Correction and Reference Oscillator

(patent pending)

The DDM 2911 and DDM 2910's oscillating U-tube with full range viscosity correction and reference oscillator (patent pending) allows long term calibration stability and measurement at all temperatures with a single calibration.

cGMP/GLP Calibration

€Calibrate the DDM 2911 and DDM 2910 with 2, 3, or more NIST Traceable Standards - calibrating with merely air and water appears inconsistent with cGMP/GLP compliance regulations. (see H&D Fitzgerald's recommendations at www.density.co.uk)
€Can print out complete method configuration, communication settings, as well as calibration verification and calibration adjustment data/history.
€Measured values can be shown continuously as temperature stability is being reached or, at the discretion of the user, measured values will only be displayed once the final answer is reached and completely stable.
€Unlimited number of customized calibration adjustments and calibration verifications possible.

Computer Windows Based Flexibility

€2 gigabytes of internal memory allow almost unlimited capacity for saving measurement data. The DDM 2911 and DDM 2910 are network ready and data may also be saved directly to your server or to any directory desired.
€Internet access is possible directly from the DDM 2911 and DDM 2910's touch screen. This feature allows real time contact with Rudolph Research Analytical's Service and Technical Support Team who can access your instrument remotely to assist in Window navigation, method setup and trouble shooting.
€Windows based navigation architecture is so intuitive that most operators will never read the manual. But should you wish to reference the manual, it is stored right on the DDM 2911 and DDM 2910's internal memory
€Copy methods, transfer concentration tables, download data, etc., via a USB port on front of unit.
€Three USB ports allow for quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick.

Versatile Communication Capability

The DDM 2911 and DDM 2910's standard communication package includes:

€Cat 5 Network Cable Connection
€3 USB ports
€2 RS 232 Ports
Allowing capability to:

€Connect directly to Rudolph's service department for remote testing and diagnostics via Internet connection.
€Connect to any Windows€ based printer via USB or direct to the server via Windows€ Print Library
€Save measurement data direct to your Network/Server

cGMP/GLP Printing

Sample measurement reports are edited quickly and easily. Just import templates from Word€ or Excel€ to the DDM 2910 or DDM 2911 Density Meter and print your company's customized "C of A" directly.

NIST Traceable Calibration Standards

Rudolph knows how important it is to calibrate with NIST Traceable Standards and therefore, we include two NIST standards in the accessories provided with all of our density meters. The DDM 2911 and DDM 2910 standard accessories include:

€Quick Start Guide
€Desiccant
€Filling Nozzles
€NIST Standards
€IQOQPQ Documentation
€Luer Syringes
€Connecting Fittings & Tubing
€Manual

Automation Flexibility

€Rudolph's AutoSampler can be loaded with up to 240 samples
€Combine density and specific gravity measurements with simultaneous measurements of:
_Refractive Index
_Color
_Optical Rotation / Specific Rotation
€Up to three different rinse solvents available for use; fully programmable
€Two sample loading modes; pressurized and suction; for optimized sample transfer and measurement
€Customer's unique sample bottles may be used to eliminate the need to transfer samples into special sized test tubes.
€Emergency samples measured at any time without stopping the AutoSampler or moving sample vials.€
