Rotothinner Viscometer

Introduction

A rotothinner viscometer measures viscosity of fluids under rotational shear conditions. It is widely used in chemical industries. The system ensures rheological analysis. It solves non-standard viscosity estimation. By providing controlled rotation, it supports fluid characterization.

Standards

ISO 3219:1993-Plastics-Determination of viscosity using a rotational viscometer with defined shear rate

ASTM D2196-20-Standard Test Methods for Rheological Properties of Non-Newtonian Materials by Rotational Viscometer

Complies with the above standards, but is not limited to them.

Features

1. Temperature control or jacket supports repeatable results.

2. Precise speed or shear settings suit different fluids.

3. Data export and reporting options support quality records.

4. Clear display shows viscosity, speed and temperature.

5. Automatic calculations and pass limits speed quality checks.

FAQ

What is the Rotothinner Viscometer mainly used for?

The Rotothinner Viscometer is used to measure the viscosity or flow behaviour of fluids. It supports formulation, batch consistency and quality control in paints, oils, food, pharmaceuticals, chemicals and cosmetics.

Which standards and regulations apply to the Rotothinner Viscometer?

The instrument is designed with reference to applicable ISO, ASTM and GB/T standards for viscosity measurement and IEC 61010 electrical safety. Procedures should follow the relevant standard method. Compliance documentation can be provided on request.

What does the warranty cover?

The system is covered for 12 months after shipment, including the main mechanism and electrical controls. Replaceable consumables and routine service items are not part of the warranty. Faults caused by improper installation outside the manual or unauthorised modification are not covered.

Will staff need special training?

Routine operation is straightforward and is covered in the user manual, including setup, daily use and basic maintenance. Staff with basic laboratory experience can run it after a short familiarisation. We provide remote guidance and can arrange on-site training where required.

How long does delivery usually take?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

How often should the Rotothinner Viscometer be calibrated?

To protect result reliability, periodic verification should be performed, typically once or twice a year. The instrument arrives factory-calibrated, and self-check routines help spot drift. We offer traceable calibration service if the site needs it.

Are the consumables universal or proprietary?

No proprietary consumable contract is required; standard parts are available from us and common laboratory suppliers. Our service team can supply a recommended parts list for the model. Most routine spares are held for quick delivery.

Can it be adapted to our requirements?

Customisation is supported for many installations, including tailored parameters, connections and accessories. Our team reviews the requirement and confirms feasibility and lead time in advance. We avoid committing to options that cannot be delivered reliably.

Is installation and commissioning included?

Benchtop and standard units typically require only placement and connection before use, while larger systems may need professional commissioning. We confirm the installation requirements at order stage. On-site service and training can be provided if needed.

What should be avoided when using the Rotothinner Viscometer?

Do not use samples outside the viscosity range, introduce bubbles or use damaged spindles. Control temperature, since viscosity is temperature dependent. Follow the operating instructions.
