SPINDLE SELECTION AND STANDARD CONFIGURATION
Define the viscosity range before ordering
A digital rotational viscometer must be matched to the expected sample viscosity, measuring temperature and required speed conditions. The standard VISCO900 package contains four application-selected spindles. A complete seven-spindle set can be ordered when the viscosity range is broad, future samples are unknown or the instrument will support method development.
Standard four-spindle set
Selected according to the declared working range. This efficient configuration avoids unnecessary spindles while covering routine samples.
Complete seven-spindle set
Useful for wider sample variability, new-product development and laboratories that do not yet know the final viscosity window.
Quotation note: Before confirming VISCO900, send the expected minimum and maximum viscosity in mPa.s, sample type, measurement temperature, available sample volume and required reporting method. This information defines the correct model, spindle set and temperature-control accessories.
Temperature control, data output and reporting options
Standard Pt100 probe
The supplied Pt100 Class A probe monitors sample temperature from -20 to 300 °C with 0.1 °C resolution.
Optional bath systems
Thermostatic bath, cooling bath and high-temperature tempering options help stabilize sample temperature for repeatable viscosity results.
Printer and PC software
Optional printer and PC software support data output, acquisition, processing, storage and viscosity curve documentation.

Applications and laboratory value
Coatings, paints and inks
VISCO900 helps laboratories document viscosity behavior of coatings, printing inks, pigments and related formulations under defined spindle, speed and temperature conditions.
Food and cosmetics
The digital rotational viscometer is suitable for creams, gels, sauces, oils, starch systems and other process samples where texture and flow behavior must be controlled.
Adhesives and polymers
Solvent adhesives, latex and polymer systems can be tested with the correct spindle package and temperature-control configuration.
Research and QC
Programmable methods, stored data, live curves, optional software and optional printing support laboratory documentation and repeatable testing.
How to choose the correct VISCO900 configuration
Choosing a digital rotational viscometer is not only a question of maximum viscosity range. The real measurement window depends on sample type, spindle geometry, rotational speed, sample temperature, measuring time and torque range. For non-Newtonian samples, the reported result should include spindle, speed, temperature and measurement time so that the method can be repeated.
VISCO900E is suitable where the standard speed set is enough for the method. VISCO900S offers a wider speed program down to 0.3 rpm and is a better choice when low-speed measurement or broader method development is required. COLO.Science can help define the correct model, four-spindle package or complete seven-spindle set, temperature-control accessory, printer and software configuration.
VISCO900 digital rotational viscometer for routine and advanced viscosity measurement
The VISCO900 digital rotational viscometer gives laboratories a practical platform for measuring viscosity under controlled and repeatable conditions. The touch-screen interface, automatic scan, range indication and live curves help operators move from simple routine checks to more structured method development. For daily QC, VISCO900 can support fast comparison of batches and product consistency. For R&D, the model selection and spindle package can be adapted to new formulations and wider application ranges.
Temperature is one of the most important factors in viscosity testing. The standard Pt100 probe monitors sample temperature directly, while optional thermostatic baths, cooling baths and high-temperature accessories help maintain stable conditions. With RS232 output, optional PC software and optional printer, the VISCO900 Series can also support documented viscosity curves, stored results and reporting workflows.
