Spindle selection is essentialThe customer must define the expected viscosity range and sample type before ordering. This information determines the correct four standard spindles. A complete seven-spindle set can also be ordered for broader application coverage.

Method-development note: Viscosity range alone is not sufficient for final selection. Provide the expected minimum and maximum viscosity, sample temperature, sample type, available volume and required shear/speed conditions so the correct model, spindle set and temperature-control accessory can be confirmed.
Values are taken from the VISCO900 source PDF. The source table labels one model as “VISVO900E”; this document uses the corrected series designation “VISCO900E”.

Spindle Selection and Standard Configuration
Required before quotation: define the working viscosity rangeThe four standard spindles are selected according to the customer’s application. Please provide the expected minimum and maximum viscosity, measuring temperature and sample description. Ordering the wrong spindle range may prevent the instrument from producing a valid measurement at the required speed and torque.
Information required
Viscosity range: expected minimum and maximum in mPa.s.
Sample: product type and whether behavior is Newtonian or non-Newtonian.
Temperature: measuring and conditioning temperature.
Standard four-spindle set
Application matched: selected to cover the declared working range.
Efficient configuration: avoids unnecessary spindles while covering routine samples.
Final selection: confirmed in the official quotation.
Complete seven-spindle set
Broad coverage: useful where sample viscosity varies substantially.
Method development: supports new products and wider R&D work.
Optional order: request the full set when future applications are uncertain.
Why spindle and speed must be considered together
The measurable range and generated torque depend on the combined selection of spindle geometry and rotational speed. VISCO900 automatically recommends an appropriate combination, but the ordered spindle set must physically cover the sample’s expected viscosity window.
For non-Newtonian materials, report the spindle, speed, temperature and measurement time together with the viscosity result to support method repeatability.

Selection and application support
COLO Lab Experts
Send the sample type, expected viscosity range, test temperature, available sample volume and required reporting method. We can confirm the model, spindle set and temperature-control configuration.
Quick contact
Confirm the working range before selecting the spindle package
The standard package contains four application-selected spindles. Choose the complete seven-spindle set when the viscosity range is broad, future samples are unknown or the instrument will support method development.
Official configuration notice: This document supports product selection and does not replace the binding specification or delivered configuration confirmed in the official COLO.Science quotation and order confirmation. Spindles, temperature-control equipment, software, printer and other options must be confirmed for the specific application.
