We price by the question you're trying to answer, not by the button we press.
Interpretation is included in everything below — you always get the read, not just the data.
Stability studies
Our core work, and the hardest to get anywhere else as a contract service. Using analytical centrifugation, we accelerate and quantify how a dispersion separates, so you learn in days what a shelf would tell you in months.
Relative stability screening
Rank two or more formulations and learn which holds and which fails first.
Shelf-life prediction
Accelerated analysis with modeling to estimate real-world stability.
Competitor benchmarking
Your product against named competitors, with the mechanism behind the difference.
Troubleshooting & optimization
Why a formulation destabilized, and what to change.
Rheology & flow behavior
How a dispersion flows is as decisive as whether it separates — and the two are connected. We characterize flow and structure across the conditions your product actually sees — at rest on a shelf, and while being pumped, sprayed, or spread. As with everything else, the interpretation is included: what the rheology says about stability, processing, and end use, not just the curves.
Flow curves & viscosity profiles
Viscosity across shear rates — how the product behaves at rest, in the bottle, in the pump, and on application.
Yield point evaluation
Whether the formulation has enough structure to hold particles and droplets in place — a yield stress that’s too low explains sedimentation faster than any shelf test.
Oscillatory testing
Amplitude and frequency sweeps — the viscoelastic fingerprint: gel or liquid, how robust the structure is, and how it responds over time and stress.
Particle size & Zeta potential
Particle size distribution (dynamic light scattering) and Zeta potential, delivered with interpretation — whether the size or charge you're seeing explains the behavior you're getting, and what it implies for stability.
Interfacial & foam characterization
Dynamic surface and interfacial tension, interfacial rheology, and foam formation and stability. The surface science that governs how emulsions and foams behave — rarely available as a contract service, and often the missing piece in a stubborn formulation problem.
Method development & consulting
When the question is bigger than a measurement: designing the right protocol, building an SOP your team can run, or working through a formulation problem end to end. Charged as project or day-rate work.
Tell us the problem, not the test.
We'll tell you the measurement that answers it, what it costs, and what you'll get back.
