Product catalog summary
Introduction
A.KRÜSS Optronic is a leading manufacturer of precision measuring devices, serving industries such as pharmaceutical, chemical, petrochemical, food, and beverage. Established in 1796, the company is known for its innovative products like refractometers, polarimeters, and density meters.
Importance of Density Measurement
Density measurement is vital for quality assurance in various industries. The oscillating U-tube method is preferred for its accuracy, speed, and minimal sample volume requirement.
Density Measurement Methods
  • Areometer: Based on buoyancy, less accurate, requires larger samples.
  • Pycnometer: More accurate but time-consuming and requires skilled personnel.
  • U-Tube Oscillator: High accuracy, minimal sample volume, quick results, ideal for industrial use.
Density Meter Models
A.KRÜSS offers digital density meters, DS7700 and DS7800, with U-tube oscillators. They differ in measurement accuracy and are suitable for various liquids and pastes, featuring manual, semi-automatic, and fully automatic sample supply options.
Advantages
  • Intuitive touch-screen operation.
  • Minimal sample volume required.
  • Efficient temperature control.
  • Compliance with GMP/GLP standards.
Performance Package
Density meters offer flexible data export, complete data recording, and backup capabilities. They support multiple languages and can integrate into existing networks or LIMS, allowing for unlimited method creation and comprehensive data reports.
Specifications and Features
Models DS7700 and DS7800 offer measurement accuracy of ±0.001 g/cm³ and ±0.0001 g/cm³, respectively. They include a U-tube oscillator, Peltier temperature control, and a touch-screen display, ensuring compliance with GMP/GLP, FDA, ISO, and other standards.
Sample Supply Methods
  • Manual: Uses a Luer syringe for sample supply, with visual checks for air bubbles.
  • Semi-Automatic: Uses a peristaltic pump for sample transfer, enhancing efficiency and safety.
  • Fully Automatic: Integrates autosamplers for unsupervised processing of up to 89 samples.
Data Management
The KrüssLab software enables device control and data management via PC, offering features like central user management and remote control.
Maintenance and Calibration
A.KRÜSS provides maintenance services, including calibration with certified liquids and firmware updates. Annual calibration is recommended for accuracy and compliance.
Technical Data
Technical specifications include measurement ranges, sample volumes, temperature control, and power consumption. Devices are made with robust materials like borosilicate glass and PTFE for chemical resistance.
Product Sets and Materials
Various sets are available for different sample supply methods, including components like drying units and syringes. Materials in contact with samples are selected for compatibility and durability.
Density Standards
  • High-purity water: Density of 0.9982 g/cm³ at 20 °C.
  • Isooctane: Density of 0.6900 g/cm³ at 20 °C.
  • N-nonane: Density of 0.7200 g/cm³ at 20 °C.
  • Dichlorotoluene: Density of 1.2500 g/cm³ at 20 °C.
  • Tetrachloroethene: Density of 1.6200 g/cm³ at 20 °C.
Equipment for Automatic Sample Supply
  • DS7700 or DS7800 Density meter with glass U-tube oscillator.
  • DS7060 Drying unit with 3/2-way valve.
  • DS7070 Peristaltic pump.
  • AS80 or AS90 Autosampler for 18 or 36 samples.
Accessories
  • DS7004 PTFE tube set for drying unit.
  • DS7071 Tube set for peristaltic pump.
  • DS7023 Adaptor for syringe sample supply.
  • DS7006 UNF nozzle.
  • DS7009 and DS7010 Luer syringes.
  • DS7019 PE waste container.

SUCCESS FACTOR DENSITY MEASUREMENT A comprehensive quality assurance covering the entire pro uction process is a must in any industrial sector. d Density measurements are frequently used for this pur pose, especially in the pharmaceutical, chemical, petro chemical as well as the food and beverage industry. They allow the manufacturer to analyse raw materials, semi-finished and finished products as well as the manu facturing steps in terms of a number of factors. Density can be used to identify substances, to determine their quality or purity and to measure their concentration in binary or quasi-binary...

MAXIMUM EFFICIENCY THROUGH AUTOMATION TYPES OF SAMPLE SUPPLY MANUAL FULLY AUTOMATIC If work is performed manually, the sample and the medium for cleaning the U-tube oscillator will be supplied with a Luer syringe. While the sample is added, you can check for air bubbles by looking through the inspection glass. A suitable medium is injected for the cleaning until all sample residues have been dissolved and removed. The drying unit will then remove all liquid residues. The semi-automatic process re quires the peristaltic pump DS7070, which will draw the required volume of the sample or the cleaning...
