To complement the viscometers, we recommend suitable products from the Measuring Instruments as well as high-quality measurement technology from leading manufacturers such as Kern and IKA. This ensures that you can carry out precise and standard-compliant viscosity measurements in your laboratory.
IKA ROTAVISC SBS me-vi HELI Complete, 100 to 40,000,000 mPas, ball bearings, electric stand, 0010013683
Anyone who frequently switches between samples during continuous operation, or moves the viscometer between several workstations, needs a mounting system that can withstand daily spindle changes without damage. The ROTAVISC SBS me-vi HELI Complete features SBS ball bearing technology and a motorised HELISTAND stand, which moves the viscometer and rotating body evenly through the sample during measurement. The scope of supply already includes the complete spindle set for the measurement range 100 to 40,000,000 mPas; the drive, stand and accessories are perfectly matched and ready for immediate use.Ball bearings instead of jewel bearingsThe SBS version (Steel Ball Bearing, Suspended) replaces the standard jewel bearings with ball bearing technology. It withstands high sample throughput, frequent spindle changes and harsh environments. Anyone who transports the instrument between multiple workstations or measures many samples per shift in quality control is better served by this design than by the more delicate standard bearing system. The spring torque of the built-in measuring spring is 0.7187 mNm, matching the measuring range of the spindles supplied in the SP set-2 kit.HELISTAND moves the sample during measurementThe motorised HELISTAND stand slowly and smoothly raises and lowers the viscometer, complete with spindle, within the sample, rather than simply allowing it to be immersed in a fixed position. This is suitable for measurements where viscosity varies with immersion depth or where uniform movement is required during the measurement series. The telescopic stroke is 142 mm, the maximum stroke at the boom is 61 mm, and the permissible dynamic load is 3.2 kg. The stand tube has a diameter of 16 mm, and the plug-in coupling for the drive is 12 mm.TFT display with ramp function and graphThe TFT display allows the speed (0.01 to 200 rpm in increments of ±0.01 rpm), timer and measured values to be read and set directly. A digital spirit level assists with alignment before the measurement begins, the ramp function automates recurring test sequences, and the graph function displays the viscosity curve during the measurement. The timer covers a range from 0.017 to 6,000 minutes and operates in both timer and continuous modes. An external temperature sensor can also be connected via PT 100; the resolution of the temperature measurement is 0.1 K, whilst RS 232 and Micro-USB transfer the measurement data to a PC.Calibration and data processingThe device can be calibrated at the measurement station and connected to laboratory software via the serial interface or USB, enabling documented measurement series without the need for manual data transfer. The motor delivers 4.8 W at the output, rotates clockwise as standard and is protected against overload. It is designed for operation at an ambient temperature of 5 to 40 °C with a maximum relative humidity of 80 per cent; the base vessel holds 600 ml of sample.Typical applicationsThe measurement range and robust design make it ideal for use where many different samples are tested in quick succession.Viscosity determination of Newtonian and non-Newtonian fluids in laboratories and quality controlHigh sample throughput with frequent spindle changes thanks to SBS ball bearingsMeasurements with a rotating body via the motorised HELISTAND standMobile use at different workstations or locationsDocumented measurement series via RS 232 or USB interfaceMeasurement series with external temperature monitoring via the PT-100 connectionTechnical detailsViscosity measurement range100 – 40,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque0.7187 mNmSpeed range0.01 – 200 rpmSpeed setting accuracy±0.01 rpmTime setting range0.017 – 6,000 minBase vessel volume600 mlOperating temperature (sample)–100 to 300 °CStandHELISTAND, motorisedStroke of telescopic stand / max. stroke142 mm / 61 mmDynamic load3.2 kgInterfacesRS-232, Micro-USBDimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgPower specifications100–240 V, 50/60 Hz, 24 W (standby 0.06 W), 24 V DC, 1000 mAProtection classIP 40 (DIN EN 60529)ContentsThe drive, tripod and spindle set are supplied fully matched in a single package; all components can be reordered individually using their respective ID numbers.1 x ROTAVISC SBS me-vi control1 x HELISTAND, motorised stand (Ident No. 0020116429)1 x T-SP-SET (Ident No. 0025007765)1 x SP set-2, spindle set (Ident No. 0025000329)1 x PT 100.8 temperature sensor (ID No. 0025000413)1 x protective bracketWarranty and procurement serviceIKA manufacturer’s warranty: 2 years, extended to 10 years upon registration at ika.com/register within 90 days of purchase. Within the ROTAVISC SBS range, the Complete packages differ primarily in their measurement range and stand. For those seeking the same me-vi range without the motion function, the ROTAVISC SBS me-vi Complete offers the version with a fixed ROTASTAND. For higher-viscosity samples, the ROTAVISC SBS hi-vi I HELI Complete and the ROTAVISC SBS hi-vi II HELI Complete are available, each featuring the same SBS ball bearing system and the same HELISTAND stand. LT Laborhandel provides support in selecting the appropriate measurement range and in sourcing further accessories such as spindles or calibration oil via its procurement service.
IKA ROTAVISC lo-vi Complete Rotational Viscometer Set, low-viscosity media, TFT touchscreen, 0010013826
Anyone who routinely tests low-viscosity liquids such as oils, paints, drinks or aqueous solutions needs a rotational viscometer that is ready to measure straight out of the box, rather than having to search for accessories first. The ROTAVISC lo-vi Complete from IKA comes as a fully integrated set comprising the measuring head, stand, spindle set and temperature probe; with its soft measuring spring, it precisely covers the range in which many laboratory quality controls are carried out: from 1 to 6,000,000 mPas.Rotational principle with a soft measuring spring for low-viscosity mediaThe lo-vi measuring system uses the softest spring in the ROTAVISC series (spring torque 0.0673 mNm) and is therefore designed for low-viscosity to medium-viscosity samples. The viscosity measurement range extends from 1 to 6,000,000 mPas with an accuracy of 1 per cent of full scale (FSR) and a repeatability of 0.2 per cent FSR. The rotational speed can be adjusted from 0.01 to 200 rpm in increments of 0.01 rpm, which allows even very flat viscosity curves to be resolved with high precision.TFT touchscreen display with trend graph and timerThe ROTAVISC lo-vi Complete is operated via a TFT touchscreen display, on which speed, torque and temperature are shown simultaneously as setpoint and actual values. An integrated graphing function displays the viscosity curve directly on the instrument, which is useful for identifying shear-thinning or shear-thickening at a glance, without first having to export the measured values to external software. For long measurement series, a timer ranging from 0.017 to 6,000 minutes is available, either in timer mode or continuous operation. A calibration function directly on the device ensures measurement accuracy throughout its service life.Temperature-controlled measurement with PT 100As viscosity is highly temperature-dependent, a PT 100.8 temperature sensor is included as standard. It has a resolution of 0.1 Kelvin and, together with the instrument, covers an operating temperature range from minus 100 to 300 degrees Celsius. Users wishing to actively control the temperature of the sample during measurement can utilise an external cooling/heating circulation bath from the range of accessories, such as the HRC 2 lite or the CBC VISC lite, which use the climate-friendly refrigerant R290. Separate measurement chambers are also available as accessories for sealed or particularly small sample volumes, enabling temperature-sensitive or volatile media to be measured under controlled conditions. An RS-232 interface and a micro-USB port are provided for connection to a process control system or the Labworldsoft 6 laboratory equipment software, allowing measurement series to be documented and analysed even outside the TFT display.Typical applicationsWith its wide measurement range, designed for low to medium viscosities, the ROTAVISC lo-vi Complete is technically suitable for:Quality control of low-viscosity products such as oils, paints, dip coatings or beveragesIncoming goods inspection of raw materials with defined viscosity specificationsRecipe and formulation development in research and developmentIn-process spot-check measurements on low- to medium-viscosity batchesTraining and teaching in rheology, thanks to the clear TFT user interfaceSelection guide within the ROTAVISC rangeIKA offers the ROTAVISC series in three measurement range variants, which differ primarily in terms of the spring stiffness of the measuring head and the spindle set supplied. All three share the same display, speed range, interfaces and housing:VariantViscosity measurement rangeSpring torqueStandROTAVISC lo-vi Complete, this unit1 to 6,000,000 mPas0.0673 mNmRotastand, manualROTAVISC me-vi HELI Complete100 to 40,000,000 mPas0.7187 mNmHelistand, motorisedROTAVISC hi-vi II Complete800 to 320,000,000 mPas5.7496 mNmRotastand, manualFor most low- to medium-viscosity standard samples in the laboratory, the lo-vi version is the right choice. If the viscosity rises into the range of pastes and highly viscous substances, the ROTAVISC hi-vi II Complete is the more suitable option. If controlled up-and-down movement of the spindle is also required, for example with non-flowing or structurally viscous samples, the ROTAVISC me-vi HELI Complete, with its motorised helix stand, is the ideal addition.Distinction from the CBC series with integrated temperature controlIn addition to the Complete set described here, in which temperature control is provided by an optional external recirculating bath, IKA offers the CBC series – a variant in which a cooling/heating bath is already permanently integrated into the viscometer. For the low-viscosity measurement range, this corresponds to the ROTAVISC CBC lo-vi Package. Users who regularly carry out measurements at defined, actively controlled temperatures thus avoid the need to set up a separate external bath; those who only occasionally work under temperature-controlled conditions will generally find the Complete Set, combined with an external thermostat such as the CBC VISC lite (which can be added as required), to be the more cost-effective option.Technical detailsViscosity measurement range1 to 6,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque0.0673 mNmGuide raillo-viMeasuring spindlesSP set-1 (SP 1 to SP 4)Motor power, output4.8 WMotor direction of rotationclockwise, with overload protectionDisplayTFT touchscreen with graph functionSpeed range0.01 to 200 rpm, setting accuracy ±0.01 rpmTorque display / measurementYesTimer0.017 to 6,000 min, timer and continuous operationOperating temperature-100 to 300 °C, temperature measurement resolution 0.1 KConnection for external temperature sensorPT 100Permissible density9999 kg/dm³Base vessel volume600 mlTest rigRotary stand, max. stroke 61 mm, Ø 16 mm, dynamic load 5 kgStroke of telescopic stand200 mmInterfacesRS 232, USB (Micro-USB)Protection classIP 40 in accordance with DIN EN 60529Dimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgPower rating100 to 240 V, 50/60 Hz, 24 WContents1 x ROTAVISC lo-vi control S000 (measuring head)1 x Rotastand (tripod)1 x SP set-1 (standard spindle set SP 1 to SP 4)1 x PT 100.8 (temperature sensor)1 x Guard rail (protective rail)Use, installation, maintenance and disposalThe device is protected against solid foreign objects from 1 millimetre in size in accordance with protection class IP 40; direct contact with splashing water must be avoided. To ensure reproducible measurement results, the stand should be placed on a level work surface with minimal vibration; the guard rail protects the spindle and measuring head from accidental contact during operation. The integrated calibration function allows for regular checks using standard silicone oils from the range of accessories; it is advisable to switch off the power before changing spindles or vessels. Spindles and the measuring vessel should be cleaned thoroughly after each measurement to ensure that dried-on residues do not distort the next measurement. At the end of its service life, the ROTAVISC lo-vi Complete, as an electrical appliance, must not be disposed of with household waste but must be placed in the separate collection for waste electrical and electronic equipment.Individual requirements & procurement serviceAdditional spindles and adaptors, measuring chambers, standard silicone oils for calibration, external circulating thermostats and the Labworldsoft 6 laboratory equipment software are available for the ROTAVISC lo-vi Complete as required. Certificates for qualification (IQ/OQ) or factory calibration can also be ordered. Through our procurement service, LT Laborhandel assists you in putting together the right accessories and selecting from our range of viscometers.Frequently Asked QuestionsIs the ROTAVISC lo-vi Complete ready for immediate use?Yes, the measuring head, rotary stand, SP set-1 spindle set, PT 100.8 temperature sensor and protective bracket are all included in the scope of delivery.What viscosity range is the instrument designed for?For 1 to 6,000,000 mPas, using the softest measuring spring in the ROTAVISC range for low- to medium-viscosity media.Can the sample be temperature-controlled during the measurement?Yes, using the supplied PT 100 probe and an optional external circulating bath from the range of accessories, such as the CBC VISC lite.What is the difference between the lo-vi and hi-vi II models?The hi-vi II Complete measures up to 320,000,000 mPas using a stiffer spring and is therefore designed for pastes and highly viscous media.Can I calibrate the device myself?A calibration function is built in, and suitable standard silicone oils are available as accessories.What interfaces are available for data transfer?RS 232 and Micro-USB, compatible with the Labworldsoft 6 laboratory instrument software.
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 pastesWith 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 timerSpeed, 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 100Many 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 applicationsWith its rigid measuring spring and extended measurement range, the ROTAVISC hi-vi II Complete is technically suitable for:Quality control of adhesives, sealants and resinsTesting of greases, pastes and high-viscosity emulsionsFormulation development for viscous formulations in research and developmentIncoming inspection of high-viscosity raw materials with defined specificationsIn-process monitoring in plastics and adhesives processingBrief overview within the ROTAVISC rangeIn 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 systemFor 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.Technical detailsViscosity measurement range800 to 320,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque5.7496 mNmMeasuring spindlesSP set-2 (SP 7 to SP 12)Motor power, output4.8 WMotor direction of rotationclockwise, with overload protectionDisplayTFT touchscreen with graph functionSpeed range0.01 to 200 rpm, setting accuracy ±0.01 rpmTorque display / measurementYesTimer0.017 to 6,000 min, timer and continuous operationOperating temperature-100 to 300 °C, temperature measurement resolution 0.1 KConnection for external temperature sensorPT 100Permissible density9999 kg/dm³Base vessel volume600 mlStandRotary stand, max. stroke 61 mm, Ø 16 mm, dynamic load 5 kgStroke of telescopic stand200 mmInterfacesRS 232, USB (Micro-USB)Protection classIP 40 in accordance with DIN EN 60529Dimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgPower rating100 to 240 V, 50/60 Hz, 24 WContents1 x ROTAVISC hi-vi II control S000 (measuring head)1 x Rotastand (tripod)1 x SP set-2 (standard spindle set SP 7 to SP 12)1 x PT 100.8 (temperature sensor)1 x Guard rail (protective rail)Use, installation, maintenance and disposalThe 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 serviceAdditional 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 QuestionsWhat 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.
IKA ROTAVISC me-vi HELI Complete Rotational Viscometer Set, motorised Helistand tripod, 0010013731
Not every sample flows evenly around the spindle of its own accord; for example, gels, ointments, creams or viscous substances tend to pool rather than flow. For precisely such cases, the ROTAVISC me-vi HELI Complete from IKA features a motorised helical stand instead of a rigid stand; this moves the spindle up and down in a controlled manner during the measurement, thereby feeding fresh sample material to the measuring head. The set combines this unique design feature with the same digital measuring head used by the other ROTAVISC variants, thereby delivering reproducible viscosity readings – which can be read directly on the instrument – even with samples that remain stationary.Medium viscosity range with motorised helistandThe me-vi measuring system operates with a spring torque of 0.7187 mNm and covers a viscosity range from 100 to 40,000,000 mPas, with an accuracy of 1 per cent of full scale (FSR) and a repeatability of 0.2 per cent FSR. Unlike the rotastand in the lo-vi and hi-vi sets, in the me-vi HELI set the motorised Helistand tripod handles the vertical movement: the spindle dips slightly deeper into the sample and back out again at defined intervals, ensuring that even samples without their own flow movement are continuously re-measured.TFT display, graph function and timerSpeed, torque and temperature are shown on the TFT touchscreen as setpoint and actual values, whilst a graphing function displays the viscosity curve directly on the instrument. 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. The supplied spindle set SP set-2 (SP 7 to SP 12) and the additional T-SP-SET are designed for the medium to high viscosity range.Temperature-controlled measurement with PT 100A PT 100.8 temperature sensor is included in the scope of delivery; it has a resolution of 0.1 Kelvin and, in conjunction with the instrument, covers an operating temperature range from minus 100 to 300 degrees Celsius. For actively temperature-controlled measurement series on non-flowing samples – such as when testing creams or gels over a defined temperature range – an external cooling/heating circulation thermostat, such as the HRC 2 lite or the CBC VISC lite, can be connected. An RS-232 interface and a micro-USB port enable connection to the Labworldsoft 6 laboratory instrument software.Typical applicationsWith its motorised Helistand tripod, the ROTAVISC me-vi HELI Complete is particularly well-suited for samples that do not flow freely:Cosmetics and pharmaceutical testing of creams, ointments and gelsQuality control of structurally viscous foodstuffs such as spreads or saucesTesting of sealants and paste-like formulations in research and developmentFormulation development for stable, non-self-levelling compoundsIn-process monitoring in the cosmetics and consumer goods industriesBrief overview within the ROTAVISC rangeIn addition to the me-vi-HELI model described here, IKA offers the ROTAVISC series in two further measuring range variants with a manual Rotastand tripod. 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, self-flowing media. The ROTAVISC hi-vi II Complete, with a stiffer spring, covers the range from 800 to 320,000,000 mPas and is designed for pastes and highly viscous media that also flow freely. If the sample does not flow freely during the measurement, the motorised Helistand stand of the me-vi-HELI set described here is the more suitable design, regardless of the viscosity range.Distinction from the CBC series with integrated temperature controlFor those who regularly carry out measurements in the me-vi range at actively controlled temperatures, the ROTAVISC CBC me-vi Package offers a variant with a permanently integrated cooling/heating bath instead of an optional external thermostat. For measurements at room temperature or with occasional use of an external thermostat, the me-vi-HELI Complete Set described here remains the more compact and flexible solution, as the Helistand tripod can be used independently of the temperature control module. For particularly intensive continuous operation, IKA also offers the combination of CBC temperature control and a more robust ball bearing system in the ROTAVISC CBC SBS me-vi Package.Technical detailsViscosity measurement range100 to 40,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque0.7187 mNmGuide railme-viMeasuring spindlesSP set-2 (SP 7 to SP 12)Motor power, output4.8 WMotor direction of rotationclockwise, with overload protectionDisplayTFT touchscreen with graph functionSpeed range0.01 to 200 rpm, setting accuracy ±0.01 rpmTorque display / measurementYesTimer0.017 to 6,000 min, timer and continuous operationOperating temperature-100 to 300 °C, temperature measurement resolution 0.1 KConnection for external temperature sensorPT 100Permissible density9999 kg/dm³Base vessel volume600 mlStandHelistand, motorised, stroke of telescopic stand 142 mmMax. stroke / Ø / dynamic load (stand)61 mm / 16 mm / 3.2 kgInterfacesRS 232, USB (Micro-USB)Protection classIP 40 in accordance with DIN EN 60529Dimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgPower rating100 to 240 V, 50/60 Hz, 24 WContents1 x ROTAVISC me-vi HELI Complete (measuring head)1 x SP set-2 (standard spindle set SP 7 to SP 12)1 x PT 100.8 (temperature sensor)1 x Helistand (motorised tripod)1 x T-SP-SETUse, installation, maintenance and disposalThe instrument is protected against solid foreign objects from 1 millimetre in size in accordance with protection class IP 40. To ensure that the Helistand can move up and down smoothly, it should be set up on a stable, vibration-free surface with sufficient headroom for the full stroke of the telescopic stand of 142 millimetres. For non-flowing, stable samples, it is advisable to clean the spindle and base vessel regularly immediately after measurement, as dried-on residues can hinder the up-and-down movement of the spindle. 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 me-vi HELI Complete, as an electrical appliance, must not be disposed of with household waste but must be placed in the separate collection for waste electrical and electronic equipment. As the Helistand stand has moving mechanical parts, it is worth carrying out a quick visual check before switching it on to ensure there is sufficient clearance, so that the up and down movement does not get caught on cables or other nearby laboratory equipment.Individual requirements & procurement serviceAdditional spindles and adaptors, measuring chambers, standard silicone oils for calibration, external circulating bath thermostats and the Labworldsoft 6 laboratory equipment software are available for the ROTAVISC me-vi HELI Complete if required, as are certificates for qualification (IQ/OQ) or factory calibration. Through our procurement service, LT Laborhandel will assist you in selecting from our range of viscometers.Frequently Asked QuestionsWhat is the motorised Helistand stand used for?It moves the spindle up and down in a controlled manner during the measurement, ensuring that even samples which do not flow freely, such as creams or gels, are continuously re-measured.What viscosity range is the me-vi model designed for?For 100 to 40,000,000 mPas, with a spring torque of 0.7187 mNm.Is the device ready for immediate use?Yes, the measuring head, Helistand, spindle set SP set-2, T-SP-SET and PT 100.8 temperature sensor are included in the scope of delivery.What distinguishes the me-vi-HELI model from the lo-vi and hi-vi-II models?The lo-vi and hi-vi-II sets operate with a manual rotary stand for self-flowing media, whilst the me-vi-HELI set moves the spindle up and down by motor and is therefore suitable for non-flowing samples.Is there a version with integrated temperature control?Yes, the ROTAVISC CBC me-vi Package features a permanently integrated cooling and heating bath instead of an optional external thermostat.
IKA ROTAVISC me-vi Complete, Rotational Viscometer 100 to 40,000,000 mPas, 0010013827
A rotational viscometer on its own is of little use if the stand and spindle set have to be purchased separately. The ROTAVISC me-vi Complete supplies the drive unit, ROTASTAND stand and SP set-2 spindle set in a single order, designed for the medium viscosity range from 100 to 40,000,000 mPas. Paints, varnishes, creams and many food samples fall precisely within this range; the package therefore covers the most common quality control testing tasks without the need for a second instrument for outlying ranges.Why the medium measurement range is the standard choiceWith an accuracy of 1 per cent of the measuring range and a repeatability of 0.2 per cent, the instrument delivers reproducible results for formulation comparisons and batch approvals. The 4.3-inch TFT display guides you through the menu; a digital spirit level helps with aligning the stand before measurement; and a ramp function automatically runs recurring test sequences. The rotational speed can be set from 0.01 to 200 rpm in increments of 0.01 rpm, for both Newtonian and non-Newtonian fluids.Set-up with the ROTASTAND telescopic standThe supplied ROTASTAND stand has a stroke of 200 mm and can support a dynamic load of 5 kg; the drive unit is secured via a 16 mm stand rod and a 12 mm push-fit coupling. For measurement series where the position does not need to be changed during the measurement, this manual design is sufficient. Those wishing to move the rotating body through the sample using a motor will find the lo-vi HELI Complete or the other HELISTAND packages in the range to be a suitable alternative.Calibration and data connectivity in everyday laboratory workThe device can be connected to a PC via RS 232 and a micro-USB interface for data logging and analysis using Labworldsoft, IKA’s measurement, control and regulation software. The integrated calibration function and the graph function on the TFT display support the traceability of measurement series without the need for additional software for basic documentation. This is particularly useful when comparing formulations across multiple batches, as the viscosity curve can be read directly on the instrument rather than simply noting a single final value.Typical applicationsQuality control of paints and coatings prior to fillingFormulation comparisons in food productionRelease testing of medium-viscosity creams and emulsionsRoutine tests in the laboratory and at goods-inSelection guide: an overview of the ROTAVISC Complete rangeEleven Complete packages cover the ROTAVISC series; they differ in four respects: viscosity range, bearings (jewel bearings or SBS ball bearings), stand (ROTASTAND or motorised HELISTAND) and the spindle set supplied.

IKA ROTAVISC lo-vi HELI Complete, Rotational Viscometer 15 to 6,000,000 mPas, Electric HELISTAND Stand, 0010013698
Low-viscosity media such as solvents, light oils or diluted dispersions place different demands on a viscometer than thick pastes. The ROTAVISC lo-vi HELI Complete measures at the lower end of the range, from 15 to 6,000,000 mPas, and features the smallest spring-loaded measuring unit in the entire family, along with a motorised HELISTAND stand that moves the rotating body slowly and evenly through the sample during measurement.Low-viscosity media require a fine torqueWith a spring measurement value of 0.0673 mNm, this instrument is designed for measurement ranges where other ROTAVISC packages reach their lower limit. As with the entire range, accuracy and repeatability are 1 per cent and 0.2 per cent of the measurement range respectively. The scope of delivery includes the SP set-1 spindle set, which covers different spindle sizes to the SP set-2 included in the other packages.The benefits of the motorised HELISTAND movementThe HELISTAND stand uses a motor to move the drive unit and rotating body up and down through the sample, enabling viscosity measurement whilst in motion rather than at a fixed point. For low-viscosity media, this ensures a consistent immersion depth throughout the entire measurement series. The scope of delivery also includes the T-SP-SET, which is required for the HELISTAND design. Those looking instead for a manual stand for the medium measuring range will find the me-vi Complete, the standard version of the series.Documenting measurement seriesFor low-viscosity media, whose values may change over time, RS 232 and Micro-USB connections to Labworldsoft are particularly useful. The integrated graph function displays the viscosity curve directly on the 4.3-inch TFT display, whilst the calibration option ensures traceable reference measurements over longer periods. In the case of solvents that are prone to evaporation, this makes it possible to quickly determine whether a value is still within the expected range or whether the sample needs to be replenished.Typical applicationsViscosity measurement of solvents and light oilsQuality control of low-viscosity dispersions and coating solutionsApproval measurements of low-viscosity cleaning and process fluidsMeasurement series where a consistent immersion depth is importantSelection guide: an overview of the ROTAVISC Complete rangeEleven Complete packages cover the ROTAVISC series; they differ in four respects: viscosity range, bearings (Juwell bearings or SBS ball bearings), stand (ROTASTAND or motorised HELISTAND) and the spindle set supplied. The lo-vi HELI Complete is the only version with the SP set-1 spindle set and also covers the lowest viscosity range in the range.

IKA ROTAVISC SBS hi-vi I HELI Complete, 200 to 80,000,000 mPas, ball bearings, electric stand, 0010013658
Viscous to paste-like samples often cannot be accurately measured within a standard measuring range; the display goes off-scale or the spindle barely turns at all. The ROTAVISC SBS hi-vi I HELI Complete covers a significantly wider range, from 200 to 80,000,000 mPas, and features SBS ball bearings as well as a motorised HELISTAND stand; it is fully assembled and ready for use with the appropriate spindle set.Designed for the hi-vi-I rangeFor the higher viscosity range, a different measuring spring is fitted compared to the me-vi model; the spring torque is 1.4374 mNm. Together with the SP set-2 spindle set, the instrument covers the range from 200 to 80,000,000 mPas, with an accuracy of 1 per cent of the measuring range and a repeatability of 0.2 per cent. The permissible density of the sample is up to 9,999 kg/dm³; the rotational speed is adjustable in increments of ±0.01 rpm across the full range from 0.01 to 200 rpm.SBS ball bearing system for continuous operationThe SBS version (Steel Ball Bearing, Suspended) replaces the jewel bearing with ball bearing technology, which is better suited to high sample throughput, frequent spindle changes and harsh environmental conditions. For businesses that use the same instrument at multiple sites or across multiple shifts, this is the appropriate choice over the more delicate standard bearing system. Both instrument variants share the same motor and display control; the difference lies solely in the bearing system.HELISTAND stand and touchscreen controlThe motorised HELISTAND stand moves the viscometer and rotating body slowly and smoothly up and down during measurement; the telescopic stroke is 142 mm, the maximum stroke at the arm is 61 mm, with a permissible dynamic load of 3.2 kg. The TFT display is used to set and read the rotational speed (0.01 to 200 rpm), timer (0.017 to 6000 min) and measured values; a ramp function automates recurring test sequences and the graph function displays the viscosity curve. The PT 100 accommodates an external temperature sensor, whilst RS 232 and Micro-USB are used to transmit the measurement data.Calibration and environmental conditionsThe instrument can be calibrated at the test station and connected to laboratory software via RS 232 or USB; this allows test series to be documented without having to transfer values manually. The motor delivers 4.8 W at the output, rotates clockwise as standard and is protected against overload. It is designed for operation at an ambient temperature of 5 to 40 °C and a maximum relative humidity of 80 per cent; the base vessel holds 600 ml of sample, the stand rod has a diameter of 16 mm, and the plug-in coupling to the drive measures 12 mm in diameter.Typical applicationsThe hi-vi-I range is suitable for samples that are already too viscous for the standard measurement range of me-vi instruments, but do not yet constitute extremely high-viscosity substances.Testing of highly viscous to paste-like samples beyond the me-vi measurement rangeQuality control with high sample throughput and frequent spindle changesMeasurements with a rotating body in motion using the motorised HELISTAND standMobile use at different workstations or locationsDocumented measurement series via RS 232 or USB interfaceMeasurement series with external temperature monitoring via the PT-100 connectionTechnical detailsViscosity measurement range200 – 80,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque1.4374 mNmSpeed range0.01 – 200 rpmSpeed setting accuracy±0.01 rpmTime setting range0.017 – 6,000 minBase vessel volume600 mlOperating temperature (sample)–100 to 300 °CStandHELISTAND, motorisedStroke of telescopic stand / max. stroke142 mm / 61 mmDynamic load3.2 kgInterfacesRS-232, Micro-USBDimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgPower specifications100–240 V, 50/60 Hz, 24 W (standby 0.06 W), 24 V DC, 1000 mAProtection classIP 40 (DIN EN 60529)Scope of deliveryThe drive, tripod and spindle set are designed to work together and are supplied as a complete package; each component can be reordered individually using its own ID number.1 x ROTAVISC SBS hi-vi I control1 x HELISTAND, motorised stand (Ident No. 0020116429)1 x T-SP-SET (Ident No. 0025007765)1 x SP set-2, spindle set (ID No. 0025000329)1 x PT 100.8 temperature sensor (ID No. 0025000413)1 x protective bracketWarranty and procurement serviceIKA manufacturer’s warranty: 2 years, extended to 10 years upon registration at ika.com/register within 90 days of purchase. For those measuring in the me-vi range, the ROTAVISC SBS me-vi HELI Complete is the ideal choice for the 100 to 40,000,000 mPas range. For even higher-viscosity samples, the ROTAVISC SBS hi-vi II HELI Complete covers the range up to 320,000,000 mPas. Those who do not require a motion function can save money with the ROTAVISC SBS hi-vi I Complete on a fixed ROTASTAND, which does not require motorised movement and is therefore slightly simpler in design. For details on spindles, calibration oil or software integration, Labworldsoft – IKA’s own laboratory equipment software – is also available. LT Laborhandel can advise on selecting the appropriate measurement range and procure further accessories via its procurement service.
IKA ROTATEMP lo-vi Package, Viscometer Set including Heating System (300 °C), Low-viscosity, 0010014004
Not every temperature-dependent sample is as viscous as bitumen. When heated, waxes, hot-melt adhesives or sweet mixtures often become thin and fluid before transitioning to a medium viscosity range, and it is precisely this lower range for which the ROTATEMP lo-vi Package is designed. It combines the ROTAVISC drive in the lo-vi range with the IKA ROTATEMP high-temperature system, which heats samples to up to 300 °C in around 16 minutes. The drive, stand, heating system and spindle set are coordinated as a complete package and ready for use.Spindle set and measuring spring for the lo-vi rangeFor lower viscosities, a more sensitive measuring spring is fitted than in the me-vi models; the spring torque is just 0.0673 mNm. Together with the SP set-1 spindle set, the instrument covers a range up to 6,000,000 mPas, with an accuracy of 1 per cent of the measuring range and a repeatability of 0.2 per cent. This means that even thinner melts remain within the measurement range, whereas with the me-vi instruments they would already be outside the resolution at the lower end.ROTATEMP high-temperature systemThe heating system is mounted directly on the boom, eliminating the need for a separate external water bath. The sample is brought to the target temperature in approximately 16 minutes using magnetic stirrer technology; according to the manufacturer, this is achieved without overheating it. According to the data sheet, the sample’s operating temperature ranges from -100 to 300 °C; of particular practical relevance for this package is the heated upper range up to 300 °C, combined with the drive’s low-viscosity measurement range.Operation and connectivityThe TFT display allows the user to set the speed (0.01 to 200 rpm), timer (0.017 to 6000 min) and measured values can be set and read directly; a ramp function automates recurring test sequences, and the graph function displays the viscosity curve throughout the heating phase. RS 232 and USB-B connect the device to the labworldsoft laboratory software for control, automation and documentation of the measurement series. An external PT-100 temperature sensor with a resolution of 0.1 K supplements the internal measurement.Operating conditions and compact designThe drive, stand and heating system form a ready-to-connect complete system with a space-saving design; there is no need for a separate setup comprising a bath, pump and tubing. The stand’s telescopic stroke is 200 mm with a permissible dynamic load of 5 kg; the base vessel holds 600 ml of sample. The unit is designed for operation at an ambient temperature of 5 to 40 °C and a maximum relative humidity of 80 per cent; the motor delivers 4.8 W at the output, rotates clockwise as standard and is protected against overload.Typical applicationsThe lo-vi range is suitable wherever samples become flowable when heated but do not reach the extreme viscosity of bitumen or similar materials.Waxes, hot-melt adhesives and polymers in the low-viscosity rangeCandy mixtures and other food melts at a defined temperatureComparative measurement series at different target temperatures up to 300 °CSamples that would be too thin for the me-vi measurement rangeQuality control with documented, reproducible heating profilesAutomated measurement series via labworldsoft and RS 232 or USB-BTechnical detailsViscosity measurement rangeup to 6,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque0.0673 mNmMeasuring spindlesSP set-1Speed range0.01, 200 rpmTime setting range0.017, 6,000 minOperating temperature-100 to 300 °CStandROTASTANDStroke of telescopic stand / max. stroke200 mm / 61 mmDynamic load5 kgBase vessel volume600 mlInterfacesRS 232, USB-BDimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgConnected load specifications100-240 V, 50/60 Hz, 24 W (standby 1.6 W), 24 V DC, 1000 mAProtection classIP 40 (DIN EN 60529)Scope of deliveryThe drive, tripod, heating system and spindle set are supplied as a pre-assembled set; each component can be reordered individually using its own identification number if required, for example for a second temperature sensor.1 x ROTAVISC lo-vi control S0001 x ROTASTAND (Ident No. 0020116428)1 x ROTATEMP high-temperature system (Ident No. 0020113825)1 x SP set-1, spindle set (Ident No. 0025000319)1 x PT 100.8 temperature probe (ID No. 0025000413)Warranty and procurement serviceIKA manufacturer’s warranty: 2 years; extended to 10 years upon registration at ika.com/register within 90 days of purchase. For regularly processed, higher-viscosity samples within the same temperature range, the ROTATEMP me-vi Package is available with a wider measurement range up to 40,000,000 mPas. For SBS ball bearings with high sample throughput, the ROTATEMP SBS me-vi Package is a robust alternative in the higher range. Those who require cooling as well as heating, for example, for samples between -25 and 125 °C, are better served by the CBC ROTAVISC lo-vi Package, where a recirculating bath thermostat takes over temperature control instead of the cantilever heating system. LT Laborhandel can advise on selecting the appropriate system and the correct measurement range, and can source further accessories, such as replacement spindles, via its procurement service.
IKA ROTATEMP SBS me-vi Package, viscometer set (SBS bearing), 300 °C, 0010013993
Anyone who regularly tests temperature-sensitive samples with varying compositions is best advised to combine two features in a single instrument: robust bearings to withstand frequent spindle changes and a heating system that reliably brings the sample up to the target temperature. The ROTATEMP SBS me-vi Package combines the SBS ball bearing system from the ROTAVISC range with the IKA ROTATEMP high-temperature system, which heats samples to up to 300 °C in around 16 minutes. The drive, stand, heating system and spindle set are coordinated as a complete package and do not need to be assembled individually.SBS ball bearing system in the me-vi rangeThe SBS version (Steel Ball Bearing, Suspended) replaces the jewel bearings found in standard instruments with ball bearing technology, which is better suited to high sample throughput, frequent spindle changes and harsh environments. The measuring range extends up to 40,000,000 mPas; the spring torque of the measuring spring is 0.7187 mNm; the SP set-2 spindle set is supplied as standard. Accuracy and repeatability remain unchanged at 1 per cent and 0.2 per cent of the measuring range respectively, as with the other ROTAVISC instruments in the range.ROTATEMP heating system on the cantileverThe heating system is mounted directly on the ROTASTAND stand and heats the sample in the boom vessel using magnetic stirrer technology, eliminating the need for a separate external water bath. According to the manufacturer, the system reaches the target temperature in approximately 16 minutes, in a controlled manner and without overheating the sample. The stand’s telescopic stroke is 200 mm with a permissible dynamic load of 5 kg, significantly more than with the standard ROTAVISC Complete packages without a heating system. According to the data sheet, the sample’s operating temperature ranges from –100 to 300 °C; the heated upper range is of practical relevance.Operation, calibration and connectivityThe TFT display allows the rotational speed (0.01 to 200 rpm), timer (0.017 to 6000 min) and measured values to be set and read directly; a ramp function automates recurring test sequences, and the graph function displays the viscosity curve during the heating phase.

An external PT-100 temperature sensor with a resolution of 0.1 K supplements the internal measurement.Operating conditionsThe instrument is designed for an ambient temperature of 5 to 40 °C at a maximum relative humidity of 80 per cent and operates in both timer and continuous modes. The base vessel holds 600 ml of sample; the motor delivers 4.8 W at the output, rotates clockwise as standard and is protected against overload. The permissible density of the sample is up to 9999 kg/dm³, which is sufficient for almost all test media encountered in practice.Typical applicationsThe combination of robust mounting and heating system is ideal wherever there is frequent switching between different, temperature-dependent samples.Viscosity measurement of asphalt, bitumen and similar road construction materials with high sample throughputWaxes, hot-melt adhesives and other temperature-dependent materials in continuous operationQuality control involving frequent spindle changes and varying test mediaMeasurement series with a defined heating phase up to 300 °COperation across multiple sites or in consecutive shiftsAutomated test series via labworldsoft and RS 232 or USB-BTechnical detailsViscosity measurement rangeup to 40,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque0.7187 mNmMeasuring spindlesSP set-2Speed range0.01 – 200 rpmTime setting range0.017 – 6000 minOperating temperature–100 to 300 °CStandROTASTANDStroke of telescopic stand / max. stroke200 mm / 61 mmDynamic load5 kgBase vessel volume600 mlInterfacesRS 232, USB-BDimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgPower specifications100–240 V, 50/60 Hz, 24 W (standby 1.6 W), 24 V DC, 1000 mAProtection classIP 40 (DIN EN 60529)ContentsThe drive, stand, heating system and spindle set are supplied as a pre-assembled set; each component can be reordered individually using its own identification number if required, for example for a second spindle set when carrying out parallel measurement series.1 x ROTAVISC SBS me-vi control1 x ROTASTAND (Ident no. 0020116428)1 x ROTATEMP high-temperature system (Ident No. 0020113825)1 x SP set-2, spindle set (ID No. 0025000329)1 x PT 100.8 temperature sensor (ID No. 0025000413)Warranty and procurement serviceIKA manufacturer’s warranty: 2 years, extended to 10 years upon registration at ika.com/register within 90 days of purchase. For those who do not require SBS ball bearings, the ROTATEMP me-vi Package offers the same combination with standard jewel bearings, which is generally sufficient for samples that are changed less frequently. For lower-viscosity samples within the same temperature range, the ROTATEMP lo-vi Package is available. Those who require cooling as well as heating – for example, for samples between –25 and 125 °C – are better served by the CBC ROTAVISC lo-vi Package, where a recirculating bath thermostat handles the temperature control. Those looking for SBS ball bearings without a heating system will find them in the ROTAVISC SBS me-vi Complete. LT Laborhandel can advise on selecting the appropriate system and the correct measurement range, and can procure further accessories, such as replacement spindles, via its procurement service.
IKA ROTAVISC hi-vi I HELI Complete, Rotational Viscometer 200 to 80,000,000 mPas, Electric HELISTAND Stand, 0010013745
Paste-like samples that channel around a fixed spindle often produce fluctuating readings at a stationary measuring point. The ROTAVISC hi-vi I HELI Complete covers a measuring range of 200 to 80,000.000 mPas with a motorised HELISTAND stand, which slowly moves the drive unit through the sample during measurement, complete with the SP set-2 spindle set and T-SP-SET.Moving measurement instead of a fixed measuring pointWith creams, gels or other semi-solid substances, the medium often moves away from the spindle during rotation and forms a channel that distorts the measurement. Instead, the HELISTAND stand moves the drive unit and rotating body slowly and evenly up and down, ensuring that the measurement does not remain fixed at a single point within the sample.Same measurement range, different design to the standard packageThe measurement range, accuracy and spring measurement value (1.4374 mNm) correspond to those of the hi-vi I Complete with ROTASTAND; the only difference lies in the stand and the supplied T-SP-SET. Those who do not need to change the specimen position during the measurement will find the manual stand a more cost-effective solution; those testing channelling media will benefit from the motorised movement of this package.Data analysis directly on the instrument or via PCThe graph function on the TFT display shows the viscosity curve in real time during the motorised HELISTAND movement; RS 232 and Micro-USB also transfer the data to a PC running Labworldsoft. The on-device calibration option complements the documentation, without requiring additional software for the basic functions. For channeling samples, the recorded curve also helps to distinguish an atypical measurement from a genuine change in consistency.Typical applicationsViscosity measurement of creams and gels that channel around the spindleQuality control of semi-solid substances in the cosmetics and pharmaceutical industriesTesting of adhesives and sealants with non-uniform flow behaviourMeasurement series where a uniform immersion depth across the sample is importantSelection guide: an overview of the ROTAVISC Complete rangeEleven Complete packages cover the ROTAVISC series; they differ in four respects: viscosity range, bearing type (Jewel bearing or SBS ball bearing), stand (ROTASTAND or motorised HELISTAND) and the spindle set supplied.

IKA ROTAVISC hi-vi II HELI Complete, Rotational Viscometer 800 to 320,000,000 mPas, Electric HELISTAND Stand, 0010013764
At the upper end of the ROTAVISC range are samples that barely flow at all, such as thick pastes, highly viscous gels or polymer melts. The ROTAVISC hi-vi II HELI Complete covers the widest measurement range in the range, from 800 to 320,000,000 mPas, and combines the spring-loaded measuring mechanism required for this with a motorised HELISTAND stand, SP set-2 spindle set and T-SP-SET.The widest measurement range in the seriesA spring measurement value of 5.7496 mNm, the highest within the ROTAVISC Complete range, makes the instrument suitable for materials that are considered semi-solid rather than liquid. As with the entire series, accuracy and repeatability remain at 1 per cent and 0.2 per cent of the measurement range, ensuring reproducible results even with very high viscosity.HELISTAND for samples that channel around the spindleNon-free-flowing substances tend to form a channel around a stationary spindle, which distorts the measurement at a fixed point. The motorised HELISTAND stand instead moves the drive unit and rotating body continuously through the sample. For those seeking the same measurement range but with more robust SBS ball bearings instead of Jewell bearings, the SBS hi-vi II HELI Complete is the ideal alternative.Reliable readings even at very high viscositiesParticularly with samples at the upper end of the measurement range, the integrated graph function helps you to check the progression of the measurement directly, rather than simply reading off a final value. RS 232 and Micro-USB are available for connection to Labworldsoft, whilst the on-board calibration function completes the documentation package. For polymer melts or sealants whose consistency depends on the processing temperature, the recorded curve can be directly compared with the process parameters.Typical applicationsTesting of high-viscosity pastes and gels in the cosmetics and pharmaceutical industriesQuality control of polymer melts and sealantsApproval measurements on virtually non-flowing materialsComparative measurements between batches at the upper end of the consistency scaleSelection guide: an overview of the ROTAVISC Complete rangeEleven Complete packages cover the ROTAVISC series; they differ in four respects: viscosity range, bearings (Juwell bearings or SBS ball bearings), stand (ROTASTAND or motorised HELISTAND) and the spindle set supplied. The hi-vi II HELI Complete, with a range of 800 to 320,000,000 mPas, is the model with the highest spring measurement value.

IKA CBC ROTAVISC SBS me-vi Package, viscometer set (cooling/heating), SBS bearing, 0010014031
The IKA CBC ROTAVISC SBS me-vi Package (MPN 0010014031) combines a rotational viscometer with a cooling and heating circulation bath to form a coordinated system solution for viscosity measurement across a wide temperature range. Viscosity is not a constant; rather, it depends heavily on temperature: Engine oil must remain fluid in winter, salad dressing must not set in the fridge, and hydraulic fluids must function both at sub-zero temperatures and under process heat. To this end, the set combines the robust ROTAVISC SBS me-vi viscometer with the CBC 5 basic cooling and heating circulation bath to form a ready-to-use unit.Two components, one coordinated systemInstead of having to assemble and coordinate a viscometer, thermostat and connecting components individually, IKA supplies the package as a fully configured system. This saves time and effort in procurement and ensures that all components are mechanically and thermally compatible with one another. Specifically, the package comprises:ROTAVISC SBS me-vi viscometer: Rotational viscometer with steel ball bearings for the medium viscosity rangeCBC 5 basic thermostat: cooling and heating circulation thermostat for the temperature range from -25 °C to +200 °CMounting bracket and stand set: positions the viscometer precisely above the thermostat bathSP set-2 spindle set: already included in the set, for different viscosity rangesPT 100.8 temperature sensor, together with a hose set and connection fittings for linking the two devicesThis combination eliminates the need to check separately whether the measuring head, bath and holder are mechanically compatible with one another – a task that would otherwise be required when individual components are selected separately.Active cooling and heating with the CBC 5 basicThe thermostat achieves a heating capacity of 2,500 watts and an active cooling capacity of 350 watts at 20 °C, thereby covering the range from -25 °C to +200 °C. In cold tests, this allows analysis of the temperature at which an oil becomes viscous or an emulsion becomes unstable. Heat tests reveal the decrease in viscosity caused by process heat. A high-performance pressure and suction pump circulates the temperature-control medium and ensures good temperature homogeneity directly at the measuring vessel, which guarantees reproducible measurement conditions across the entire temperature range.SBS bearings for everyday laboratory useThe measuring head in this package is the SBS version of the ROTAVISC me-vi. SBS stands for Steel Ball Bearing. Compared to the more delicate sapphire bearing, this technology is significantly more resilient to impacts or rough handling during spindle changes and is therefore suitable for laboratories with high sample throughput or changing staff. The more robust bearing system really pays off in day-to-day use, particularly when frequently switching between different spindles from the supplied SP set-2 spindle set. The viscosity range (me-vi) extends from 100 to 40,000,000 mPas and covers typical applications such as varnishes, paints, oils and foodstuffs.Operation and accuracyThe 4.3-inch TFT display shows all measured values at a glance, whilst the menu navigation supports ramp functions and timer control. A digital spirit level assists with the correct alignment of the instrument, which is essential for reliable viscosity measurements. The measurement accuracy is ± 1 % (F.S.), and the repeatability is ± 0.2 % (F.S.) – values that are sufficient for quality control where documentation is required and which can be logged via the digital interfaces.Software integration for automated measurement sequencesBoth the thermostat and the viscometer are equipped with USB and RS-232 interfaces. Using the optional labworldsoft software, both devices can be linked to automatically run and document temperature-viscosity profiles; for example, whilst the thermostat ramps up from –20 °C to +100 °C and the viscosity of the sample is monitored in real time on the PC. For laboratories that need to document rheograms across multiple temperature stages, this eliminates the need for manual transfer of individual measurement points.Typical applicationsThe SBS me-vi Package is suitable for viscosity tests in which both low-temperature and high-temperature behaviour are equally relevant:Automotive and lubricants industry: low-temperature flow behaviour of engine and gearbox oilsFood industry: Consistency testing of dressings, sauces and creams at fridge temperaturePaints and coatings industry: viscosity control in production and quality assurance processesChemical industry: Testing of hydraulic fluids over a wide temperature rangeResearch and development: automated temperature-viscosity profiles (rheograms) using labworldsoftIn all these areas, the package replaces the combination of a separate viscometer, bath and connection technology that would otherwise be required with a tested, all-in-one solution that is ready for use immediately after set-up.Technical detailsViscosity range (me-vi)100 to 40,000,000 mPasBearingSBS (steel ball bearings)Thermostat typeCooling and heating circulation thermostatTemperature range-25 °C to +200 °CHeating power2,500 WCooling capacity350 W (at 20 °C)Viscosity accuracy± 1 % (F.S.)Reproducibility± 0.2 % (F.S.)Display4.3-inch TFTInterfacesUSB, RS 232 (both units)Pump capacityHigh-performance pressure/suction pumpContents1 x IKA ROTAVISC SBS me-vi (measuring head)1 x IKA CBC 5 basic (cooling/heating thermostat)1 x Mounting bracket/tripod set for mounting above the bath1 x SP set-2 spindle set1 x PT 100.8 temperature sensor1 x Hose set and connection fittings1 x mains lead and operating instructionsCustomised requirements & procurement serviceA suitable thermal fluid (bath fluid) for the intended temperature range is required for operation; special oils or glycols are used for sub-zero temperatures.

IKA ROTAVISC SBS me-vi Complete, Rotational Viscometer 100 to 40,000,000 mPas, SBS Ball Bearings, 0010013824
In laboratories with multiple users and frequent spindle changes, a jewel bearing is more delicate than necessary. The ROTAVISC SBS me-vi Complete replaces it with an SBS ball bearing (Steel Ball Bearing, Suspended) and thus covers the same measurement range of 100 to 40,000,000 mPas as the standard package, complete with a ROTASTAND stand and SP set-2 spindle set.SBS bearing instead of jewel bearingThe SBS ball bearing technology is more robust than the traditional jewel bearing and is more forgiving of minor carelessness when attaching and removing the spindle. The measuring range, accuracy of 1 per cent of the measuring range and spring measurement value of 0.7187 mNm correspond to the me-vi Complete with Juwell bearings; the only difference lies in the bearing type.For laboratories with high sample throughputWhere several teams work on the same instrument or spindles are changed several times a day, the more robust bearing system pays off. The ROTASTAND stand with a 200 mm stroke remains manually adjustable, for measurement series at a fixed position above the sample. Paints, varnishes and food samples in the medium viscosity range can thus be tested reliably, even with frequent changes of user. A dynamic load of 5 kg and a stroke of 200 mm provide sufficient flexibility to position vessels of varying heights beneath the spindle without having to reconfigure the stand.Interfaces for multi-user laboratoriesWhere several users work on the same device, the connection to Labworldsoft via RS 232 or Micro-USB helps to document measurement series consistently rather than having to transfer them manually. Calibration options and a graphing function are already integrated and are available regardless of the user. For laboratories where several teams analyse the same dataset, this significantly reduces the effort involved in transferring individual measurement values.Typical applicationsHigh-usage laboratory workstations with frequent spindle changesQuality control of paints, varnishes and foodstuffs in the medium viscosity rangeTraining and practical laboratories with changing usersRoutine measurements where robustness takes precedence over fine adjustmentSelection guide: an overview of the ROTAVISC Complete rangeEleven Complete packages cover the ROTAVISC series; they differ in four respects: viscosity range, bearing type (Jewel bearing or SBS ball bearing), stand (ROTASTAND or motorised HELISTAND) and the spindle set supplied. The SBS me-vi Complete is the more robust variant for the medium measurement range with a standard stand. Those who require a motorised stand instead of a manual ROTASTAND will find the SBS me-vi HELI Complete offers the same bearing configuration with HELISTAND movement; those who prefer the classic Jewel bearing should choose the me-vi Complete.PackageViscosity rangeMountingStandSpindle setROTAVISC me-vi Complete100 to 40,000,000 mPasJewell bearingsROTASTANDSP set-2ROTAVISC hi-vi I Complete200 to 80,000,000 mPasJuwellagerROTASTANDSP set-2ROTAVISC lo-vi HELI Complete15 to 6,000,000 mPasJuwellagerHELISTAND (electric)SP set-1ROTAVISC hi-vi I HELI Complete200 to 80,000,000 mPasJuwellagerHELISTAND (electric)SP set-2ROTAVISC hi-vi II HELI Complete800 to 320,000,000 mPasJuwellagerHELISTAND (electric)SP set-2ROTAVISC SBS me-vi Complete (this package)100 to 40,000,000 mPasSBS ball bearingsROTASTANDSP set-2ROTAVISC SBS hi-vi I Complete200 to 80,000,000 mPasSBS ball bearingsROTASTANDSP set-2ROTAVISC SBS hi-vi II Complete800 to 320,000,000 mPasSBS ball bearingsROTASTANDSP set-2ROTAVISC SBS me-vi HELI Complete100 to 40,000,000 mPasSBS ball bearingsHELISTAND (electric)SP set-2ROTAVISC SBS hi-vi I HELI Complete200 to 80,000,000 mPasSBS ball bearingsHELISTAND (electric)SP set-2ROTAVISC SBS hi-vi II HELI Complete800 to 320,000,000 mPasSBS ball bearingsHELISTAND (electric)SP set-2Technical detailsViscosity measurement range100 to 40,000,000 mPasAccuracy (FSR)1 % of the measuring rangeRepeatability (FSR)0.2% of the measurement rangeSpeed range0.01 to 200 rpmSpeed setting accuracy±0.01 rpmMotor power, output4.8 WSpring measurement value (torque)0.7187 mNmMeasuring spindles, basic configurationSP set-2StandROTASTAND (manual telescopic stand)Time setting range for timer0.017 to 6000 minOperating temperature (sample)-100 to 300 °CPermissible ambient temperature range5 to 40 °CPermissible relative humidity80 %InterfacesRS 232, USB (Micro-USB)Connected load100-240 V, 50/60 Hz, 24 W (standby 0.06 W), 24 V DC / 1000 mAProtection classIP 40 (DIN EN 60529)Dimensions (W x H x D, drive unit)351 x 629 x 372 mmWeight (drive unit)7.1 kgScope of delivery1 x ROTAVISC SBS me-vi control, drive unit (part of package ID no. 0010013824)1 x ROTASTAND, ID No. 00201164281 x Spindle set SP set-2, ID No. 00250003291 x PT 100.8 temperature sensor, ID No. 00250004131 x Guard railWarranty and procurement serviceIKA provides a 2-year manufacturer’s warranty on the instrument; this is extended to 10 years if the instrument is registered at ika.com/register within 90 days of purchase.

IKA ROTAVISC SBS hi-vi II Complete, Rotational Viscometer 800 to 320,000,000 mPas, SBS Ball Bearings, 0010013822
This package is designed to handle very viscous samples and high-throughput laboratory work. The ROTAVISC SBS hi-vi II Complete covers the widest measurement range in the series, from 800 to 320,000.000 mPas, the widest measurement range in the series, and combines this with the more robust SBS ball bearing system instead of the classic jewel bearing system, complete with a ROTASTAND stand and SP set-2 spindle set.The most robust variant for the toughest samplesA spring measurement value of 5.7496 mNm, the highest in the entire ROTAVISC Complete range, makes the instrument suitable for thick pastes, gels and polymer melts. Accuracy and repeatability remain at 1 per cent and 0.2 per cent of the measurement range, whilst the SBS bearing assembly absorbs the mechanical stress generated by highly viscous samples and frequent spindle changes. The supplied spindle set SP set-2 covers the entire range from 800 to 320,000,000 mPas, eliminating the need to procure additional spindles for individual batches.SBS bearings in the rigours of everyday laboratory useWhere several users work on the same instrument or where samples with highly variable consistency are tested, the SBS ball bearing is more forgiving than a Jewell bearing. Those seeking the same measurement range with a motorised stand for channelling media will find the SBS hi-vi II HELI Complete to be the ideal alternative; those who prefer the standard Juwell bearing configuration should choose the hi-vi II HELI Complete.Data analysis with high sample throughputWith high sample throughput, the RS 232 or Micro-USB connection to Labworldsoft reduces the effort required for documentation compared to manual data transfer. Calibration options and a graphing function are integrated into the instrument, ensuring traceable results even with very high-viscosity samples. When a series of measurements across multiple batches is analysed, the viscosity trend for each individual measurement can be traced directly, rather than simply recording the final value.Typical applicationsBusy laboratory workstations with frequent spindle changes when handling highly viscous samplesQuality control of highly viscous pastes and gels in the cosmetics and pharmaceutical industriesTesting of polymer melts and sealants in continuous operationRoutine measurements at the upper end of the consistency scale, with a focus on robustnessSelection guide: an overview of the ROTAVISC Complete rangeEleven Complete packages cover the ROTAVISC series; they differ in four respects: viscosity range, bearing type (Jewel bearing or SBS ball bearing), stand (ROTASTAND or motorised HELISTAND) and the spindle set supplied.

IKA ROTAVISC SBS hi-vi I Complete, Rotational Viscometer 200 to 80,000,000 mPas, SBS Ball Bearings, 0010013820
More viscous media and a laboratory environment with frequent changes of user place two different demands on a viscometer, which this package combines. The ROTAVISC SBS hi-vi I Complete covers a range from 200 to 80,000,000 mPas and replaces the traditional jewel bearing with the more robust SBS ball bearing technology, complete with a ROTASTAND stand and SP set-2 spindle set.Robust technology for more viscous mediaThe spring measurement value of 1.4374 mNm corresponds to that of the hi-vi I Complete with a Jewell bearing; accuracy and repeatability remain unchanged at 1 per cent and 0.2 per cent of the measurement range. Pastes, adhesives and thicker creams can be tested just as reliably; the SBS bearing system simply withstands greater mechanical stress than a Jewell bearing.Frequent spindle changes without wear concernsIn laboratories where several people work on the same instrument and spindles are changed several times a day, the SBS ball bearing reduces the risk of damaging the more delicate Jewell bearing through careless handling. The ROTASTAND stand remains manually and securely positioned, ensuring measurement series are carried out without any movement during the test. The SP set-2 spindle set fully covers the measurement range from 200 to 80,000,000 mPas, without the need to order additional spindles for individual test tasks.Documentation across multiple shiftsIn laboratories operating in shifts, the connection via RS 232 or Micro-USB to Labworldsoft ensures consistent reports, regardless of who carried out the measurement. The integrated calibration function and the graph function on the TFT display complement the basic documentation directly on the device, without the need for a separate evaluation scheme for each shift.

IKA ROTATEMP me-vi Package, viscometer set including heating system (300 °C), 0010014015
Asphalt, bitumen, wax and hot-melt adhesives are not fluid at room temperature; their viscosity can only be measured accurately when they are warm or hot. The ROTATEMP me-vi Package combines the ROTAVISC rotational viscometer in the me-vi measuring range with the IKA ROTATEMP high-temperature system, which uses magnetic stirring technology to heat samples to up to 300 °C in around 16 minutes without overheating them. The drive, stand, heating system and spindle set are designed to work together as a complete package and do not need to be assembled individually.Heating system instead of a separate water bathThe ROTATEMP high-temperature system is mounted directly onto the stand and heats the sample in the cantilever vessel; this eliminates the need for an additional external water bath for temperature-dependent measurements up to 300 °C. According to the manufacturer, the system reaches the target temperature in around 16 minutes; the controlled heating is designed to prevent the temperature from overshooting, thereby making the measurement more reproducible. According to the data sheet, the sample’s operating temperature ranges from –100 to 300 °C; for this package, the upper, heated range is of practical relevance.Viscosimeter for the me-vi rangeThe ROTAVISC drive, fitted with standard jewel bearings, measures in the range up to 40,000,000 mPas, with an accuracy of 1 per cent of the measuring range and a repeatability of 0.2 per cent. The SP set-2 spindle set is supplied as standard; the spring torque of the measuring spring is 0.7187 mNm. The TFT display allows the speed (0.01 to 200 rpm), timer (0.017 to 6,000 min) and measured values to be set and read directly. An external PT-100 temperature sensor supplements the measurement; its resolution is 0.1 K.Compact complete systemThe drive, ROTASTAND stand and heating system form a ready-to-connect complete system with a space-saving design, eliminating the need for a separate setup comprising a bath, pump and hoses. The device can be connected to the labworldsoft laboratory software via RS 232 or USB-B for automated measurement series, control and documentation. The stand’s telescopic stroke is 200 mm with a permissible dynamic load of 5 kg, significantly more than with the standard ROTAVISC Complete package without a heating system.Operating conditions and operationThe instrument is designed for an ambient temperature of 5 to 40 °C at a maximum relative humidity of 80 per cent and operates in both timer and continuous modes. A digital spirit level facilitates alignment before measurement begins, a ramp function automates recurring test sequences, and the graph function displays the viscosity curve during the heating phase and the actual measurement. The base vessel holds 600 ml of sample; the motor delivers 4.8 W at the output, rotates clockwise as standard and is protected against overload.Typical applicationsThis package is suitable wherever viscosity only becomes relevant as the temperature rises and a fixed target temperature must be reached in the cantilever vessel, for example with samples that are solid or viscous at room temperature.Viscosity measurement of asphalt, bitumen and similar road construction materialsWaxes, hot-melt adhesives and other temperature-dependent materialsPolymers and confectionery mixtures that only become flowable when warmMeasurement series with a defined heating phase up to 300 °CComparative measurement series at different target temperaturesAutomated measurement series via labworldsoft and RS 232 or USB-BTechnical detailsViscosity measurement rangeup to 40,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque0.7187 mNmMeasuring spindlesSP set-2Speed range0.01 – 200 rpmTime setting range0.017 – 6000 minOperating temperature–100 to 300 °CStandROTASTANDStroke of telescopic stand / max. stroke200 mm / 61 mmDynamic load5 kgBase vessel volume600 mlInterfacesRS 232, USB-BDimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgPower specifications100–240 V, 50/60 Hz, 24 W (standby 1.6 W), 24 V DC, 1000 mAProtection classIP 40 (DIN EN 60529)ContentsThe drive, stand, heating system and spindle set together form the complete, pre-assembled package.

For those who regularly test lower-viscosity samples within the same temperature range, the ROTATEMP lo-vi Package is the ideal choice. For high sample throughput with frequent spindle changes, the same me-vi combination with SBS ball bearings is available as the ROTATEMP SBS me-vi Package. Those who require cooling as well as heating – for example, for samples between –25 and 125 °C – are better served by the CBC ROTAVISC lo-vi Package, where a recirculating bath thermostat handles temperature control instead of the cantilever heating system. LT Laborhandel provides advice on selecting the appropriate temperature control system, the correct measurement range and additional accessories such as replacement spindles via its procurement service.
IKA ROTAVISC hi-vi I Complete, Rotational Viscometer 200 to 80,000,000 mPas, 0010013828
As soon as a sample becomes more viscous than a paint, such as a paste, an adhesive or a thicker cream, the measuring range of the me-vi package is no longer sufficient to ensure accurate results. The ROTAVISC hi-vi I Complete covers a range from 200 to 80,000,000 mPas and comes complete with a ROTASTAND stand and SP set-2 spindle set, meaning a single order is sufficient for routine measurements of higher-viscosity samples.When the sample becomes more viscous than with the me-viThe wider measurement range results in a different spring constant; for this instrument, it is 1.4374 mNm compared with 0.7187 mNm for the me-vi package. Accuracy and repeatability remain the same at 1 per cent of the measurement range and 0.2 per cent, as do the speed range, TFT display and ramp function. For adhesives, thicker creams and pastes with a still-flowable consistency, the device is therefore a direct upward extension of the me-vi package.ROTASTAND for stationary measurement seriesAs with the me-vi Complete, the ROTASTAND stand is manually adjustable, with a 200 mm stroke and a dynamic load of 5 kg. The drive unit is fixed in position above the sample, which is practical for series of measurements at consistent locations within the laboratory. If the rotating body needs to be moved motorised through the sample during the measurement, for example, because the medium is channelled around the spindle, the hi-vi I HELI Complete, with the same measurement range, is the suitable alternative.Interfaces for data loggingRS 232 and a micro-USB interface are available for connection to a PC system, compatible with IKA’s Labworldsoft laboratory equipment software. Calibration options and a graphing function are already integrated into the instrument, ensuring that test reports remain traceable even when testing viscous media such as adhesives or pastes. Anyone comparing measurement series across several batches can view the viscosity curve directly on the TFT display, without first having to process the raw data on an external computer.Typical applicationsTesting of adhesives and sealants of medium to high consistencyQuality control of pastes and thicker creams in the cosmetics and pharmaceutical industriesApproval measurements of viscous food products such as fillings or spreadsComparative measurements between batches with varying viscositySelection guide: an overview of the ROTAVISC Complete rangeEleven Complete packages cover the ROTAVISC series; they differ in four respects: viscosity range, bearing type (Jewel bearings or SBS ball bearings), stand (ROTASTAND or motorised HELISTAND) and the spindle set supplied.

IKA ROTAVISC SBS hi-vi II HELI Complete, 800 to 320,000,000 mPas, Ball Bearings, Electric Stand, 0010013672
At the upper end of the viscosity spectrum, for viscous pastes, putties or spreadable compounds just below their yield point, a rotational viscometer requires a stronger measuring spring and a bearing assembly capable of withstanding the correspondingly high forces. With a range of 800 to 320,000000 mPas, the widest measurement range in the ROTAVISC-SBS-HELI series, and comes as a complete package featuring SBS ball bearings and a motorised HELISTAND stand.The widest measurement range in the seriesThe hi-vi II range features the most powerful measuring spring in the ROTAVISC SBS family; the spring torque is 5.7496 mNm, more than four times that of the me-vi version. In combination with the SP set-2 spindle set, the instrument covers the range from 800 to 320,000.000 mPas with an accuracy of 1 per cent of the measuring range and a repeatability of 0.2 per cent, the same values as for the other ROTAVISC-SBS models in the series.SBS ball bearing design to resist wearWith highly viscous samples, significantly higher forces act on the bearings than with low-viscosity media; the SBS version (Steel Ball Bearing, Suspended) withstands this better than the jewel bearings used in standard instruments. This proves particularly beneficial where there are frequent changes between samples of varying viscosity or where the instrument is used to process several batches in succession. The drive and display control are identical to those of the other ROTAVISC-SBS instruments in the range; the only difference lies in the measuring spring and spindle assembly.HELISTAND stand, display and interfacesThe motorised HELISTAND stand moves the viscometer and rotating body slowly and smoothly through the sample; the telescopic stroke is 142 mm, the maximum stroke at the boom is 61 mm, and the permissible dynamic load is 3.2 kg. The TFT display allows the rotational speed (0.01 to 200 rpm), timer (0.017 to 6000 min) and measured values to be set and read directly; a ramp function automates recurring test sequences. The PT 100 accommodates an external temperature sensor, whilst RS-232 and Micro-USB transmit the measurement data to a PC or laboratory software.Calibration and environmental conditionsThe unit can be calibrated at the test station and is protected against overload; the motor delivers 4.8 W at the output and rotates clockwise as standard. It is designed for operation at an ambient temperature of 5 to 40 °C and a maximum relative humidity of 80 per cent; the base vessel holds 600 ml of sample, whilst the stand rod has a diameter of 16 mm with a 12 mm plug-in coupling.Typical applicationsThe hi-vi-II range is intended for samples that would already be too viscous for the hi-vi-I range, such as highly viscous substances just below their yield point. Thanks to the SBS ball bearing system, switching between spindles and test series remains reproducible.Testing of extremely high-viscosity samples beyond the hi-vi-I measurement rangeQuality control with high sample throughput and frequent spindle changesMeasurements with a rotating body via the motorised HELISTAND standMobile use at different workstations or locationsDocumented measurement series via RS 232 or USB interfaceMeasurement series with external temperature monitoring via the PT-100 connectionTechnical detailsViscosity measurement range800, 320,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque5.7496 mNmSpeed range0.01, 200 rpmSpeed setting accuracy±0.01 rpmTime setting range0.017, 6,000 minBase vessel volume600 mlOperating temperature (sample)-100 to 300 °CStandHELISTAND, motorisedStroke of telescopic stand / max. stroke142 mm / 61 mmDynamic load3.2 kgInterfacesRS-232, Micro-USBDimensions (W x H x D)351 x 629 x 372 mmWeight7.1 kgConnected load specifications100-240 V, 50/60 Hz, 24 W (standby 0.06 W), 24 V DC, 1000 mAProtection classIP 40 (DIN EN 60529)Scope of deliveryThe drive, stand and spindle set are designed to work together and are supplied as a complete, pre-assembled package.

IKA CBC ROTAVISC me-vi Package, viscometer set (cooling/heating), 0010014058
The universal all-in-one solution for temperature-dependent viscometry: IKA CBC ROTAVISC me-vi Package The IKA CBC ROTAVISC me-vi Package (MPN 0010014058) is the answer to the most common requirement in rheological laboratories: “We need to measure various samples precisely at different temperatures.” Whether you need to test the storage stability of a cream at low temperatures, assess the workability of a paint at room temperature, or simulate the flow behaviour of hot melt adhesive – this package makes it possible. It seamlessly combines the IKA ROTAVISC me-vi, the standard for medium viscosities, with the CBC 5 basic dynamic cold and hot circulation bath. The “me-vi” range: the heart of viscometry The measuring head of this system is the ROTAVISC me-vi (“Medium Viscosity”). With an immense measuring range of 100 to 40,000,000 mPas, it covers precisely the range within which most industrial and chemical products fall. Typical applications include: Paints & coatings: Determining spreadability and flow behaviour. Cosmetics & Pharmaceuticals: Analysis of the consistency of ointments, shampoos, lotions or toothpaste. Food: Quality control of mayonnaise, dairy products, chocolate or sauces. Chemicals: Characterisation of polymer solutions and adhesives. The instrument utilises a proven sapphire bearing (‘jewel bearing’), which guarantees high sensitivity whilst ensuring a long service life when operated correctly. The measurement accuracy of ± 1 % and the reproducibility of ± 0.2 % (relative to the full-scale value) ensure reliable data on which you can base your quality decisions. Master the climate: CBC 5 basic Viscosity is inextricably linked to temperature. A deviation of just 1 °C can lead to measurement errors of over 10 % with some oils or polymers. The CBC 5 basic circulating bath included in the set eliminates this uncertainty. It offers an extremely wide operating temperature range from -25 °C to +200 °C. Active cooling: Even if you ‘only’ want to measure at 20 °C, an active cooler is often necessary to dissipate the frictional heat from the spindle or to compensate for high ambient temperatures in summer. It also enables low-temperature tests (e.g. winter resistance of diesel or cosmetics). Powerful heating: With 2,500 watts, the unit heats the bath in a flash, minimising waiting times between different temperature settings. Excellent circulation: The powerful pressure and suction pump ensures turbulent mixing of the bath medium. This guarantees that the temperature at the measuring cup corresponds exactly to that shown on the display. An integrated system The major advantage of this ‘Solution’ package is its mechanical and thermal integration. The viscometer is not simply placed next to the thermostat, but is mounted directly above the bath using a special bracket. The measuring cup is immersed in the temperature-controlled liquid. This ensures optimum heat transfer without the losses that can occur with external hose temperature control. The system is compact, tidy and saves valuable space on the lab bench. Smart laboratory: ramping and documentation For modern R&D departments, static measurement is often not enough. You want to know: “How does my product change as it cools down?” Thanks to the USB and RS-232 interfaces on both devices (viscometer and thermostat), you can connect the system to a PC. Use the labworldsoft software® (optional) to synchronise both devices. Fully automatic temperature ramps: Create programmes in which the thermostat follows a temperature curve whilst the viscometer continuously collects data. Live visualisation: See immediately on-screen at which point a structure breaks down or curing begins. Data integrity: Save all measured values in a tamper-proof format. Focus on ease of use Despite the complex capabilities, operation is remarkably simple. The ROTAVISC’s 4.3" TFT display guides you intuitively through the menus. A digital spirit level assists with the precise horizontal alignment of the instrument. The Quick-Connector coupling enables spindles to be changed quickly with one hand.

IKA CBC ROTAVISC lo-vi Package, viscometer set (cooling/heating), low-viscosity, 0010014045
Some viscosity measurements do not require heating up to 300 °C, but rather a precisely maintained temperature between cold and warm; this applies, for example, to samples that are to be tested at fridge temperature or whose flow behaviour needs to be documented across a wide temperature range. The CBC ROTAVISC lo-vi Package combines the ROTAVISC drive in the lo-vi range with the CBC VISC lite cooling and heating circulation thermostat, which controls the temperature of the sample directly in the heating bath between –25 and 125 °C. The drive, stand, bath and spindle set are coordinated as a complete kit and ready for use.The CBC VISC lite cools and heats in the same bathUnlike the ROTATEMP packages, which only heat, the CBC VISC lite bath can also actively cool samples. The temperature range extends from -25 to 125 °C; the bath uses the natural refrigerant R290 (propane) and has space for two standard 600 ml beakers, allowing a second beaker to be pre-conditioned whilst the measurement is in progress. An easily removable air filter maintains a constant cooling capacity over time without the need to open the bath.Measurement directly in the bath or via an external connectionFor the measurement, the sample is tempered directly in the bath of the CBC VISC lite; an external pump connection also allows DIN-standard vessels to be heated for the determination of absolute viscosity using ELVAS spindles or double-walled beakers. The ROTAVISC drive measures in the low-to-high viscosity range from 1 to 6,000,000 mPas, with an accuracy of 1 per cent of the measuring range and a repeatability of 0.2 per cent; the SP set-1 spindle set is supplied as standard. The spring torque of the measuring spring is 0.0673 mNm, designed for low-viscosity samples in this range.Operation and connectivityThe TFT display allows the rotational speed (0.01 to 200 rpm), timer (0.017 to 6,000 min) and measured values to be set and read directly; a ramp function automates recurring test sequences, and the graph function displays the viscosity curve over the temperature ramp. RS 232 and USB-B connect the device to the labworldsoft laboratory software for control, automation and documentation of the measurement series. An external PT-100 temperature sensor with a resolution of 0.1 K supplements the internal measurement, whilst a digital spirit level assists with alignment before the measurement begins.Operating conditionsThe ROTAVISC drive is designed for an ambient temperature of 5 to 40 °C at a maximum relative humidity of 80 per cent, regardless of the sample temperature set in the bath. The motor delivers 4.8 W at the output, rotates clockwise as standard and is protected against overload. The permissible density of the sample is up to 9999 kg/dm³, whilst the base vessel on the drive itself has a capacity of 600 ml.Typical applicationsThis package is suitable wherever samples need to be tested within a defined temperature range between cold and warm.Viscosity measurement at refrigeration or room temperature between –25 and 125 °CComparative measurement series over a wide temperature range in a bathAbsolute viscosity determination in accordance with DIN via an external pump connection using ELVAS spindlesSamples that would be too low-viscosity for the me-vi measuring rangeParallel pre-conditioning of a second beaker whilst the measurement is in progressTests using natural refrigerants as an alternative to conventional refrigerantsAutomated measurement series via labworldsoft and RS 232 or USB-BTechnical detailsViscosity measurement range1 – 6,000,000 mPasAccuracy (FSR)1 %Repeatability (FSR)0.2 %Spring torque0.0673 mNmMeasuring spindlesSP set-1Temperature range CBC VISC lite–25 to 125 °CCapacity of the CBC VISC lite2 standard beakers, 600 ml eachRefrigerant CBC VISC liteR290 (propane, natural refrigerant)Speed range0.01 – 200 rpmTime setting range0.017 – 6,000 minStandROTASTANDBase vessel volume600 mlInterfacesRS 232, USB-BPower specifications (ROTAVISC drive)100–240 V, 50/60 Hz, 24 W (standby 1.6 W), 24 V =, 1000 mAProtection class (ROTAVISC drive)IP 40 (DIN EN 60529)Scope of deliveryThe drive, stand, circulation bath and spindle set are supplied as a pre-assembled, ready-to-use set; each component can be reordered individually using its own identification number if required, such as an additional beaker for alternating use in the bath.1 x ROTAVISC lo-vi control S0001 x ROTASTAND (Ident No. 0020116428)1 x CBC VISC lite heating bath and circulating thermostat, R290 (Ident No. 0020102007)1 x SP set-1, spindle set (ID No. 0025000319)1 x PT 100.8 temperature probe (ID No. 0025000413)Warranty and procurement serviceIKA manufacturer’s warranty: 2 years; extended to 10 years upon registration at ika.com/register within 90 days of purchase. For those who do not require active cooling and only need to heat up to 300 °C, the ROTATEMP lo-vi Package offers a suitable alternative with a cantilever heating system instead of a bath, though without a cooling function below room temperature. For those carrying out measurements without a temperature control system at all, the ROTAVISC lo-vi HELI Complete on a motorised stand is the ideal choice. LT Laborhandel can advise on selecting the appropriate temperature control system and the correct measurement range, and can source further accessories such as ELVAS spindles or replacement glassware via its procurement service.
