Rotational Viscometers
Rotastand me-vi HELI-Stand hi-vi II Rotastand lo-vi

The new ROTAVISC series determines the viscosity of liquids in all areas of application ranging from the laboratory to quality control. The four devices measure in different viscosity ranges. Regardless of a simple or demanding viscosity measurement - the ROTAVISC delivers rapid and accurate results.

Viscometers are used in numerous industries of product development, quality and process control. They provide information on the flowability of liquids, which is a crucial quality characteristic in industries such as the food and cosmetics industry. Based on the viscosity, important decisions regarding the design of production plants or the suitable packaging are made.

The rotational viscometers of the ROTAVISC series determine the viscosity of liquids in all areas of application ranging from laboratory to quality control. In conjunction with suitable accessories, the four devices can deliver relative and absolute measurement results in different viscosity ranges. Regardless of simple or demanding viscosity measurement - thanks to latest technology ROTAVISC provides highly precise measurement results with a good reproducibility of ±0.2%.


Features

  • Two stands available - manual (Complete Model) and motorized (Helistand Model) which moves the mounted viscometer and its rotating body slowly and uniformly up and down in the sample.
  • Easy to operate - The generous 4.3" TFT display allows for an intuitive menu guidance. A digital spirit level also supports the correct set-up of the start-up condition. The simple ramp function simplifies repetitive tasks.
  • Highest measurement accuracy - The level of measurement accuracy of the ROTAVISC rotational viscometer for both Newtonian and non-Newtonian fluids is ±1 % of the measuring range. The reproducibility is ±0.2 %.
  • Temperature sensor - The temperature sensor is always included in the scope of delivery, because it is ecommended to measure the viscosity in relation to a temperature value.
  • Temperature control - By using suitable accessories it is possible to measure samples from -100°C to 300°C.
  • Stepless positioning - The ROTASTAND ensures perpendicular stability. The height of the viscometer can be adjusted steplessly.
  • Multiple mountings - Thread adaption, quick connector or hook connector: You attach the spindle to the device in the way that you find most convenient.
  • 3 measuring modes - Three measuring modes are available for different applications: accurate, balance and fast.
  • Different programs - Ten different programs and ramps can be stored.
  • Functions - The starting and stopping of a measurement can be defined individually: With a timer, once a certain torque has been achieved, or once the viscosity has been measured. Labworldsoft® enables any number of program and data recordings.
  • Interfaces - There are connection possibilities available for USB and RS 232. This means that control via a PC and data capture are possible.
  • Spindles - Four spindles are included in the delivery of ROTAVISC lo-vi; six spindles are included in the me-vi and hi-vi packages.
  • The multilingual and intuitive menu navigation ensures easy handling and operation.
  • The user defines the starting and stopping of a measurement individually: with a timer, once a certain torque has been achieved, or once the viscosity has been measured. Labworldsoft® 6 Visc enables networking and control of the viscometer with thermostat and additional sensors as well as any number of program and data storages. Moreover, the software supports the requirements of FDA CFR 21 Part 11.
  • ROTAVISC offers greatest possible flexibility to the user. Different kinds of stands and spindles can be used depending on the viscosity that needs to be measured. We offer different solutions depending on the application and viscosity measuring range.

Rotavisc Complete Viscometer FAQ's

  1. Which IKA rotational viscometer is the most suitable for my sample?
    • lo-vi: for juices, solvents, edible oils, inks, liquid soap.
    • me-vi: for paints / varnishes, mayonnaise, dairy products, ketchup.
    • hi-vi I & hi-vi II: for pastes, ointments, molasses, gels.

  2. How can the accuracy of the ROTAVISC be checked?
    IKA sells standard liquids with a viscosity determined at 25°C. The user can check his or her device using these fluids.

  3. How is the spindle mounted on the device?
    The delivery includes three different adaptations.
    1. The spindle is screwed onto the device.
    2. The spindle is attached to the device by means of a quick-fitting adapter.
    3. The spindle is attached to the device by means of a hook adapter.

  4. How long does a measurement take?
    To obtain a stable viscosity value, the spindle should have completed 3 to 4 full revolutions in the medium. The lower the speed, the longer a measurement takes.

  5. How deep does the spindle have to be immersed into the test medium?
    Each spindle has a mark on the shaft. The spindle must be immersed into the medium up to this point.

  6. What is the smallest viscosity that can be measured using ROTAVISC?
    1 mPas with lo-vi and ELVAS-1 at 60 rpm.

  7. How exactly does the IKA ROTAVISC work?
    The rotational viscometer measures the torque required to turn a spindle immersed in a medium. The spindle is driven by a motor that uses a calibrated spring. The deflection serves as a measurement of the torque and is shown in the display as M%.

  8. How much sample volume is needed?
    The standard spindles in the scope of delivery are suitable for a volume of approx. 500 ml in the 600 ml beaker (low form). Smaller sample volumes can be measured with the absolute measuring systems (coaxial measuring system), such as with the VOLS-1 adapter.

  9. Why does ROTAVISC measure different viscosities for the same sample?
    Generally, viscosity is not a substance-specific constant. The viscosity describes a substance in a well-defined state, for instance at temperature X and speed Y. There are samples which reduce their viscosity with increasing speed, for example ketchup (shear thinning / pseudoplastic). For other samples, the viscosity increases with increasing speed, for example starch solutions (shear thickening / dilatant). Also there are samples that do not change their viscosity either as the speed increases or decreases, such as silicone oil (Newtonian fluid).

  10. Which measured values does ROTAVISC output?
    Temperature: °C or °F
    Speed: rpm
    Measuring time: hh:mm:ss
    Torque: M%
    Viscosity: mPas, cP, m2/s, cSt
    Stop conditions: Time, torque, temperature, viscosity spindle
    Density: g/cm3
    Shear rate: 1/s (when using a coaxial measuring system)
    Shear stress: PA (when using a coaxial measuring system)

  11. How high should the maximum speed be?
    Here it is important that the speed and the spindle are chosen so that the laminar flow range is not deviated from. Otherwise, the viscosity values will be too high. For the geometries SP-1, SP-2, SP-6 and ELVAS-SP, the following transition points to a turbulent flow were determined.
    1. SP-1 lo-vi,15 mPas at 60 rpm > rpm / mPas = 4
    2. SP-2 lo-vi 100 mPas at 200 rpm > rpm / mPas = 2
    3. SP-6 me-vi 100 mPas at 50 rpm > rpm / mPas = 0.5
    4. ELVAS-SP 0.85 mPas at 60 rpm > rpm / mPas = 70.6
    If the ratio of rpm / mPas exceeds these values, turbulent conditions can occur with the spindles listed. Artificially higher viscosity values can occur with the geometries VAN-SP-1 to VAN-SP-4, due to turbulence at speeds of more than 10 rpm.

Accessories

Labworldsoft 6 Visc Software enables the automation of laboratory processes by connecting ROTAVISC viscometers to other devices, such as a thermostat, through a PC. Measurement processes and parameters can thus be easily recorded for analysis and documentation. In addition, users can e.g. monitor and control the sample temperature and pH measurement. Labworldsoft Software includes a measurment file database, electronic signatures and is compatible with Windows 7, 8, and 10.
