Density Meter Methods Screen

Rudolph Density Meters offer VideoView™ Bubble Detection

VideoView provides superior high resolution visual bubble detection within your sample with live on-screen video viewing. The U-Tube may be viewed at 2X, 6X and 10X magnification, for the entire U-tube. The 10X magnification is also extremely helpful in detecting the cleanliness of the glass U-tube. Both images may be saved with sample results and may be viewed and or printed as desired.


A full view of the entire U-tube is possible without any obstruction. Automatic Scanning of U-tube under the 10X magnification of the entire U-tube and manual control is possible to view any position of the U-tube for bubble detection. The clarity, magnification and resolution is the very best available. Rudolph’s exclusive VideoView is protected under Patent #7,437,909.

  • 2X, 6X and 10X magnification U-tube is possible.
  • The entire view of the U-tube is available for both images.
  • Both images are saved and can be viewed, exported and/or printed with measurement results.
  • Automatic Bubble detection is available which will flag the sample(s) with suspected bubble.

Computer Windows Embedded Based Flexibility

  • 32 gigabytes of internal memory allow almost unlimited capacity for saving measurement data. The DDM 2911 PLUS is 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 PLUS touch screen. The Disk Protection feature protects the operating system against malware infections in networked environments.
  • 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 PLUS internal memory.
  • Copy methods, transfer concentration tables, download data, etc., via the USB ports on the front of unit.
  • Five USB ports allow for quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick.
  • Embedded Windows 7 prevents any and all viruses and malware.

Density Meter Loading Options

Vertical Load – A Rudolph Exclusive Feature

• Helps with sample injection is done against gravity. 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 waste jar. As opposed to the traditional horizontal load, if the waste tubing was bent, the sample would pour backwards and spill out on the table.

• Preserves the nozzles and nozzle bodies much better since there will not be added pressure from pushing on them when loading a sample. All the pressure will be on the top plate, thus saving in future maintenance costs.


LoadAssit®

• Great option as there is two ways to inject a sample: by manual injection or having the PeriPump pull the syringe for you.

• Ideal for pulling the rinse solutions automatically into the system thus making the rinsing part of the operation much easier.

• Pressure mode available for carbonated samples.

• Has no added benefit to measurement performance over the Horizontal Load for an experienced user. However it 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 compared to HL or VL option.


MM Peri Pump

• Most versatile option. Allows three ways to inject the sample: through the supplied needle, manual injection or having the PeriPump (LA).

• Has no added benefit to measurement performance over the Horizontal Load for an experienced user. However it benefits customers that have multiple inexperienced users as the PeriPump will automatically inject the sample the same way every time.

• An added benefit is the cleaning process, or possible lack of cleaning and going right into your next sample which will decrease operational times.

• Yields same results as a VL or HL or LA for all non-viscous types of samples, so no change in performance occurs.


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 is required.


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 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.


AutoFlex R837 Automation System

The DDM Series of density meters can be combined with various Rudolph Automation Systems and Sample Handling Accessories.
Available are Peristaltic Pumping, Heated Sampler, the ECS (Easy Clean System), and the Rudolph R837 AutoFlex Sampler.

The Rudolph Research R837 AutoFlex is perfect for high throughput laboratories
looking to increase productivity.

• System Configuration minimal sample volume: 1.5 mL

• A heated interface is available

• Fast throughput.

• Automation saves operator time and increases your lab’s efficiency
• An urgent-sample interruption can be made at any time

Operation is completely automatic. The sample is measured and the data recorded. Depending on how the system is configured the data may also be printed, saved as an Excel file or transferred to a LIMS system


Full Automation

Multiple measurements from one sample, with full automation and automatic cleaning and drying.

Description

Combine instruments with Automation to Measure: Refractive Index, BRIX, Density, Specific Gravity, Optical Rotation, Color, Alcohol % vol/vol, Proof and more all from a single sample.

AutoFlex gives you the most flexibility in sample vial selection, sample handling and instrument combinations.

Ideal for high throughput Flavor, Fragrance, Alcohol, Chemical, Petroleum, Food Labs who run many samples each day and want automatic cleaning of the system.


AlcoTest®-RI

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 with high solids and/or high sugar based flavorings

 Producers of wine who wish to quickly measure alcohol % by vol/vol

 Producers of beer and other malt beverages

 Distilled Products with Obscuration

For alcohol % by vol/vol the following accuracies apply

better ±0.01 % v/v with DDM 2911 PLUS – TTB Compliant for high proof spirits

better ±0.04 % v/v with DDM 2911

better ±0.07 % v/v with DDM 2910

For obscured products, accuracies will vary by product. Ask for a demonstration or sample study.
