Several probe options

Sigma Solo can be used with platinum Du Noüy ring, platinum, and paper Wilhelmy plates, and platinum rod. Using the paper plate removes the need for cleaning as the plates are disposable. Using the platinum rod, allows surface tension measurements of small volumes, down to few ml.

Built-in bubble level and ambient temperature monitoring

Sigma Solo has a built-in bubble level indicator close to the balance to ensure levelness where it matters the most. Ambient temperature sensor monitors the environment constantly for better result traceability.

Optional functionalities

Advanced sample stage

Include advanced sample stage to add stirrer, or possibility to connect temperature or pH sensors. Add temperature vessel to control sample temperatures between -20 to +200C. 

Ionizer

Add built-in ionizer to reduce the static charge of the sample. Especially meaningful when measuring very small forces such as in fiber wettability. 

Chamber doors

Add doors to the instrument to protect the measurement chamber from airflow.
