What we measure

The attributes your customers actually feel

Each measurement uses an instrument configured for your specific product -- the right probe, the right motion, the right speed. We do not force your sample into a generic test.

01

Spreadability

How easily a product rubs out on skin or a surface. The instrument spreads it the way a person does -- circular or linear motion, controlled load -- and records the friction coefficient throughout.

02

Stickiness and stringiness

The probe goes into the product and pulls back out. You get the peak adhesion force and how far the material stretches before it breaks. Two numbers that define "how sticky is this?"

03

Dispensability

How much product comes out of the actual package at a given squeeze force. We test in the container your customers use -- the tube, the pump, the bottle -- not a laboratory fixture.

04

Visual behavior

A synchronized camera records every test. You see what happens as the product spreads, strings, or breaks -- something no other instrument provides. The video ships with every report.

How it works

Samples in, numbers out

We built this process for teams that need answers, not another vendor relationship to manage.

1

Tell us the attribute

Describe what your customers care about -- how it spreads, how it strings, how it squeezes out. We design the measurement protocol around your product and lock every variable so results stay comparable over time.

2

Ship your samples

Send them in their real packaging. Testing in the container your customers actually squeeze, pump, or scoop from is part of the measurement, not a complication we try to avoid.

3

Get a numeric report

Measured values with clear comparisons against your baseline or reference samples. Not adjectives -- numbers. Which supplier matches your reference, by how much, and where each one falls short.

When to call us

Problems we solve every week

Supplier selection

You approached ten factories and they sent you ten samples. You give them to us and we give you a table -- not a panel result, but a clear breakdown. This one dispenses at 23 mm/s, that one at 56. This one strings, that one does not. Real numbers that let you hand a factory a spec.

Batch consistency

Send one sample from every production run. We compare each batch against your locked baseline and flag drift before your customers feel it. The measurement protocol stays fixed, so every result is directly comparable to the last.

Reformulation validation

You changed the formula and need to know whether consumers will notice. We measure the old version and the new one under identical conditions and tell you exactly what shifted -- and by how much.

Sensory panel correlation

Panel data is statistically tricky: rating scales, just-noticeable differences, attribute correlations. We connect your existing sensory data to instrumental measurements using methods from our published literature, so you know what the instrument number means in human terms.

Why Perceptometry Lab

We built the instruments. We wrote the methods.

The protocols we use are the same emulative, tribological, and rheological methods documented in our 22 peer-reviewed publications. And because we design and fabricate every instrument in-house, we adapt the measurement to your product -- not the other way around.

A standard tribometer costs over $100,000 and measures one thing. A standard texture analyzer measures something else. Our instrument does both, adds a camera, and costs a fraction of either. When you send us samples, that is the instrument running your test.
