Bring rotational viscosity measurement and controlled vertical spindle travel together. The IKA ROTAVISC SBS me-vi HELI Complete combines the ball-bearing viscometer with a motorized HELISTAND, standard spindles, T-spindles and a PT 100.8 temperature sensor.

Use the standard spindle format for an appropriately specified fluid test, or the T-spindle/HELI arrangement for suitable non-flowing samples. The manufacturer’s 100–40,000,000 mPa·s model range is an overall selection reference, not a promise that every spindle measures every sample throughout that span.

Exact US package 0010013684. The head’s power adapter and motorized stand have separate electrical requirements. This is not a blanket universal-voltage kit. Sample vessels, calibration oil, a temperature-control bath and software are not listed as included.

For comparative formulation and QC methods

A useful format when viscosity is evaluated under defined conditions. Specify spindle, speed, temperature, vessel, timing and sample history so results can be compared meaningfully.

For suitable non-flowing samples

IKA identifies the T-spindle/HELISTAND arrangement for creams, pastes and gels. Vertical travel changes the measuring path; it does not make every material Newtonian or remove the need for a validated method.

For frequent spindle changes

The SBS ball-bearing design is intended for robust handling and repeated spindle changes. It still requires correct mounting, leveling, inspection and calibration checks; robustness is not permission to mishandle the shaft.

For a range that suits the actual sample

me-vi is not automatically a better choice than lo-vi for thin liquids. Confirm the sample’s expected behavior, attainable torque and selected spindle range rather than choosing only by the largest viscosity number.

A factory instrument, stand and spindle package

• ROTAVISC SBS me-vi control viscometer head.
• HELISTAND motorized stand.
• T-SP-SET: six T-spindles, with nut, coupling and carrying case per the set instructions.
• SP set-2: six standard spindles, SP7, SP8, SP9, SP10, SP11 and SP12.
• PT 100.8 temperature sensor and guard rail.

The head manual additionally lists the extension arm, mounting hardware, temperature-sensor clamp, power supply, USB cable and documentation. HELISTAND has its own power-cord set. The exact factory package order number remains 0010013684; this is not a merchant-created bundle.

Not listed as supplied: sample beakers or sample material, calibration oils, temperature-control equipment, a software license, coaxial measuring systems, low-volume or very-low-viscosity adapters. A sensor measures temperature; it does not actively heat or cool the sample.

Use the right geometry and stand mode

The six standard SP7–SP12 spindles support separately specified rotational tests. Choose the spindle and speed so the expected viscosity produces suitable torque under the applicable vessel and immersion conditions.

For non-flowing samples, the HELISTAND moves the mounted head and T-spindle through the sample. The stand manual says to activate motorized travel only with T-spindles and to use that mode without the ROTAVISC guard rail. The included guard rail is not an instruction to fit it during motorized HELI operation.

For me-vi with T-spindles, the recommended maximum speed is 10 rpm. The head’s general 0.01–200 rpm capability is not a recommendation to run T-spindles at 200 rpm. The T-SP manual also says this set is not recommended for calibration checking.

Spindle travel, sample depth, clearance and the limit-stop positions must be set for the actual vessel. Keep the spindle clear of the vessel walls, bottom and exposed moving parts; follow the stand manual rather than using a headline stroke value as a ready-made method.

Choose spindle and speed before interpreting the percentage

IKA specifies viscosity accuracy of ±1% of full-scale range (FSR) and repeatability of ±0.2% FSR. These are not the same as ±1% or ±0.2% of every displayed result.

For illustration, a selected full scale of 10,000 mPa·s makes 1% equal to 100 mPa·s. At a reading of 2,000 mPa·s, that same 100 mPa·s is 5% of the reading. This is an explanation of the specification, not a full uncertainty budget or a guaranteed sample result.

The current head manual identifies an optimum torque trend of greater than 10% and less than 100%. Use a suitable spindle/speed combination and the displayed full scale rather than accepting a reading simply because a number appears on the screen.

Temperature, air bubbles, vessel geometry, immersion, time and sample history also affect a method. Non-Newtonian materials may change apparent viscosity with speed and elapsed time; record those conditions instead of treating every result as a single intrinsic material constant.

Keep the method conditions alongside the viscosity result

The 4.3-inch TFT interface provides spindle/speed selection, torque display, timer, graph functions and method-program controls. Digital leveling supports setup. A computer purchase is not required for local measurements.

The included PT 100.8 sensor helps measure sample temperature. The general head temperature-input range is not permission to expose every supplied spindle, seal, cable or vessel to every temperature in that range. Confirm the sensor, sample and setup limits separately.

Use an appropriate external temperature-control arrangement when the method requires one. The package does not supply a bath or establish a direct connection to a particular circulator. Record actual sample temperature; room temperature alone does not prove the sample has equilibrated.

Micro-USB and RS-232 support separately configured data/control workflows described in the manual. No labworldsoft license, validated electronic-recordkeeping compliance or automatic regulatory method approval is implied.

Make every comparison traceable to its test conditions

• Define the expected material behavior, vessel, temperature, spindle geometry and comparison goal.
• Install and level the instrument, check the head and stand power requirements, and perform the manual’s setup/self-check steps.
• Mount the correct spindle and use the appropriate stand mode, guard-rail arrangement, immersion and clearance.
• Select suitable speed and torque, then use a consistent test time and HELI travel protocol where applicable.
• Record spindle, speed, torque/full scale, temperature, timing and sample history; clean and inspect as instructed.

For standard-spindle measurements, the head manual describes constant temperature, no bubbles on the spindle, liquid at the spindle-shaft mark and more than 10 mm bottom clearance under its reference setup. These conditions are not automatically a universal protocol for every T-spindle or optional geometry.
