Product information "IKA ROTAVISC hi-vi II Complete Rotational Viscometer Set, for high-viscosity media and pastes, 0010013829"
Pastes, adhesives, resins or greases are often difficult to measure reliably using a standard viscometer, as their flow behaviour lies well outside the measuring range for low-viscosity media. The ROTAVISC hi-vi II Complete from IKA is fitted with the stiffest measuring spring in the ROTAVISC range and, as a complete set comprising a stand, spindles and a temperature probe, covers a range from 800 to 320,000,000 mPas.
Rigid measuring spring for highly viscous media and pastes
With a spring torque of 5.7496 mNm, the hi-vi-II measuring system operates with significantly greater stiffness than the lo-vi and me-vi variants of the series and is therefore specifically designed for viscous to paste-like samples. The viscosity measurement range extends from 800 to 320,000,000 mPas with an accuracy of 1 per cent of full scale (FSR) and a repeatability of 0.2 per cent FSR. The supplied spindle set SP set-2 (SP 7 to SP 12) is designed for the higher viscosity range and delivers a stable, analysable torque signal even with viscous substances.
TFT display, torque measurement and timer
Speed, torque and temperature are displayed on the TFT touchscreen as setpoint and actual values; the integrated graphing function records the viscosity curve directly on the instrument. This is particularly useful with highly viscous media, as it enables the early detection of structural viscosity or sample hardening during the measurement. The speed range extends from 0.01 to 200 rpm with a setting accuracy of ±0.01 rpm; the timer covers 0.017 to 6,000 minutes in timer or continuous operation. A calibration function is integrated directly into the device. The integrated overload protection reacts if a very viscous or already set sample subjects the motor to a load exceeding the permissible torque, thereby preventing damage to the measuring head during prolonged, unattended measurement runs.
Temperature-controlled measurement with PT 100
Many highly viscous media, such as melts, resins or temperature-dependent pastes, exhibit significant changes in viscosity even with small temperature fluctuations. The PT 100.8 sensor included in the scope of delivery has a resolution of 0.1 Kelvin and, together with the instrument, covers an operating temperature range from minus 100 to 300 degrees Celsius. For actively temperature-controlled measurement series, an external cooling/heating circulation bath such as the HRC 2 lite or the CBC VISC lite can be connected; for documenting the measurement series, an RS-232 interface and a micro-USB port are available for the Labworldsoft 6 laboratory instrument software.
Typical applications
With its rigid measuring spring and extended measurement range, the ROTAVISC hi-vi II Complete is technically suitable for:
- Quality control of adhesives, sealants and resins
- Testing of greases, pastes and high-viscosity emulsions
- Formulation development for viscous formulations in research and development
- Incoming inspection of high-viscosity raw materials with defined specifications
- In-process monitoring in plastics and adhesives processing
Brief overview within the ROTAVISC range
In addition to the hi-vi-II model described here, IKA offers the ROTAVISC series in two further measurement range variants. The ROTAVISC lo-vi Complete measures from 1 to 6,000,000 mPas using a softer spring and is suitable for low-viscosity to medium-viscosity media. The ROTAVISC me-vi HELI Complete covers a medium range from 100 to 40,000,000 mPas and also includes a motorised Helistand tripod for samples that do not flow freely during measurement. As a rough guide: users who regularly switch between low-viscosity and paste-like batches when changing samples are often better served by the hi-vi-II set described here, together with an additional lo-vi spindle set from the range of accessories, than by using two separate instruments.
Distinction from the SBS series with a more robust ball bearing system
For applications involving particularly frequent spindle changes or continuous operation under high mechanical stress, IKA also offers the hi-vi series in an SBS version with a more robust ball bearing system: the ROTAVISC SBS hi-vi II Complete. For the vast majority of routine laboratory measurements, the standard bearing arrangement of the Complete set described here is sufficient; the SBS variant is particularly worthwhile for very intensive, multi-shift use.

Use, installation, maintenance and disposal
The instrument is protected against solid foreign objects from 1 millimetre in size in accordance with protection class IP 40. In the case of viscous, sticky or hardening media, it is recommended that the spindle and measuring vessel be cleaned immediately after each measurement, before residues dry out and make cleaning more difficult or distort the next measurement. The stand should be placed on a stable, level surface so that the high rigidity of the measuring spring is not compromised by vibrations. It is advisable to switch off the power to the device before changing the spindle or vessel. At the end of its service life, the ROTAVISC hi-vi II Complete, as an electrical appliance, must not be disposed of with household waste but must be placed in the separate collection scheme for end-of-life electrical equipment. As highly viscous media are often difficult to remove from the base vessel, it is advisable, in the case of very sticky samples, to clean the equipment promptly immediately after cooling, whilst residues can still be dissolved using standard commercial solvents.
Individual requirements & procurement service
Additional spindles and adapters for other viscosity ranges, measuring chambers, standard silicone oils for calibration, external circulating thermostats and the Labworldsoft 6 laboratory equipment software are available for the ROTAVISC hi-vi II Complete as required, as are certificates for qualification (IQ/OQ) or factory calibration. An additional spindle set for the low-viscosity range (SP set-1) can also be retrofitted if, in addition to viscous media, you occasionally need to analyse more fluid samples. Through our procurement service, LT Laborhandel will assist you in selecting from our range of viscometers.
Frequently Asked Questions
What viscosity range is the hi-vi-II model designed for?
For 800 to 320,000,000 mPas, using the stiffest measuring spring in the ROTAVISC range for highly viscous media and pastes.
Is the instrument ready for immediate use?
Yes, the measuring head, rotary stand, SP set-2 spindle set, PT 100.8 temperature sensor and protective bracket are all included in the scope of delivery.
What distinguishes the hi-vi-II model from the lo-vi model?
The lo-vi Complete measures from 1 to 6,000,000 mPas using a softer spring and is suitable for low-viscosity to medium-viscosity media.
Is there a version with a more robust bearing system?
Yes, the SBS variant, the ROTAVISC SBS hi-vi II Complete, features a more robust ball bearing system for very intensive use.
Can the sample be temperature-controlled during the measurement?
Using the supplied PT-100 probe and an optional external circulating bath, such as the CBC VISC lite or HRC 2 lite.
Can I also measure lower-viscosity samples with the same instrument?
With an additional SP-set-1 spindle set (available separately), the measurement range can be extended to cover lower viscosities; for very low-viscosity media, the ROTAVISC lo-vi Complete remains the more accurate choice.
