The interpretation is included.
Every service below ends with the read — what the results mean, why, and what to do next — not just the data. And it’s priced by the question you’re trying to answer.
Stability & shelf-life
Our core work: how a product separates, and how fast — measured directly, in real time, under acceleration, or both, and turned into a decision you can defend.
Relative stability screening
Two or more formulations, ranked — which holds, which fails first, and why.
Shelf-life prediction
Accelerated analysis with modeling — a real-world stability estimate you can put a date on.
Competitor benchmarking
Your product against named competitors, with the mechanism behind the difference.
Troubleshooting & optimization
Why a formulation destabilized, and what to change.
Particle size & zeta potential
Full distributions by the technique the sample calls for — dynamic light scattering, laser diffraction, single-particle counting, or analytical centrifugation — with the read on whether the size you’re seeing explains the behavior you’re getting. Zeta potential where it earns its place: as the trend that shows what a formulation change did to particle charge — not as a stability verdict.
Size distribution analysis
Full distributions — not just a mean — by the technique the sample calls for.
Batch-to-batch comparison
Whether a drift is aggregation, coalescence, or just batch-to-batch noise.
Zeta potential trending
What a formulation change did to particle charge — tracked, not overread.
Rheology & flow
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 — and read it for what it 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 counting
Single-particle counting and sizing in liquids, for the jobs where routine tests report ‘nothing detected’: trace contamination in clean fluids, particles shed into a batch, filter and membrane performance verified with actual counts. You get the number — how many, and how big — and the read on whether it’s a problem.
Trace contamination counting
How many particles, and how big — in fluids that read ‘nothing detected.’
Filter & membrane performance
Upstream versus downstream — what got through, with actual counts.
Batch & ingredient screening
Particles shed into a product — found, sized, and traced.
Foam & interfacial behavior
Foam performance as numbers — how readily it builds, how long it holds, how fast it drains — under controlled, repeatable generation, at the temperature your application actually runs at. Beneath it, the interfacial measurements — dynamic surface and interfacial tension, interfacial rheology, adsorption kinetics — for the emulsion or foam problem that a formulation tweak alone won’t fix.
Foamability & foam stability
How readily it builds and how long it holds — controlled generation, at application temperature.
Defoamer selection & dosing
Candidates compared and proven — the right chemistry at the right dose.
Drainage & bubble size
How a foam ages, quantified — the structure behind the collapse.
Interfacial characterization
Dynamic tension, interfacial rheology, adsorption kinetics — the mechanism level.
Method development & consulting
When the question is bigger than a measurement: designing the right protocol, building an SOP your team can run, working through a formulation problem end to end — or tuning a process like homogenization by measurement rather than feel. Charged as project or day-rate work.
