DisperTester 3000 Plus
Rubber Dispersion Tester
For cured or uncured rubber compounds, optical dispersion testing is the fastest test method for quickly characterizing filler dispersion.
The DisperTester 3000 Plus rubber carbon black dispersion tester features a new telecentric Carl Zeiss optical system paired with the latest generation in digital image processing. The specialized camera is mounted on a motorized panning system, allowing up to five readings without adjusting sample placement. With different magnification levels available, discerning and quantifying levels of filler dispersion, or agglomeration, is easier than ever.

Create Optically Flat Specimens. Every time.
Repeatable measurements hinge on perfect sample preparation. With the DisperCut, samples are stretched while cutting to avoid smearing, contamination, or unevenness in the usable cross section. In less than one second, samples are prepared. For highest operator safety, the unit is fit with two hand operation including anti-tiedown, and an automatic knife cover.
Considerations for Non-Vulcanized Test Specimens
Uncured test specimens have a higher propensity of smearing when being cut, which can skew test results. For uncured samples and more viscous materials, the DisperCool can greatly help with sample preparation. Samples are emersed in the DisperCool’s pre-chilled silicone oil at temperatures as low as -40°C for a predetermined amount of time, bringing the material to glass transition levels. Once hardened by chilling, the material is capable of producing cleaner cuts for cross-section examination and dispersion testing.
