With Ultrapyc’s rapid method selection and built-in accessories, users can transition from sample reception to measurement execution, and finally to result analysis on the touchscreen or within Anton Paar’s AP Connect lab execution system, in less than three minutes.
Ultrapyc can perform measurements independently in under a minute, making it ideal for monitoring the quality of the samples during the manufacturing process.
The process of conducting density measurements for solid pieces, powders, slurries, and semi-solids has reached unprecedented speed and accuracy.
Key Features
Automate for Accuracy
The Ultrapyc series instruments automatically determine the best settings and accurately regulate temperature, thereby removing the necessity for manual modifications and minimizing the potential for user mistakes.
When combined with the TruLock lid, which ensures a uniform and repeatable chamber volume, Ultrapyc gas pycnometers provide the utmost precision in analyzing solid and semi-solid densities.
