What your nano lab actually checks
Fast charge titration, 5 params at once
Every measuring point returns zeta potential, streaming potential, conductivity, pH and temperature. A pH, polyelectrolyte or salt titration to the isoelectric point runs in 5–15 minutes with hundreds of data points — on concentrated samples up to 40 vol%, no heavy dilution.
An applications engineer on the line
Charge titration, isoelectric-point and dispersant-optimization method development, plus combined size-and-zeta with the NANOTRAC FLEX, from engineers who run characterization in-house at ATO Lab. Sub-4h reply, NDA standard.
The Microtrac STABINO ZETA is a zeta-potential and particle-charge analyzer built for fast, precise charge titration. Using the streaming-potential method — not slow electrophoresis — it measures five parameters at once (zeta potential, streaming potential, conductivity, pH and temperature) on every data point, for particles from 0.3 nm to 300 µm at up to 40 vol% concentration. A full pH, polyelectrolyte or salt titration to the isoelectric point takes only minutes.
Why colloid and formulation labs choose the STABINO ZETA
Charge, stability and isoelectric point in minutes — on concentrated, real samples.
Five parameters at once
Each measuring point returns zeta potential, streaming potential, conductivity, pH and temperature — a full charge fingerprint, not a single number.
Fast, precise titration
Mix-and-measure titration runs a pH, polyelectrolyte or salt curve in 5–15 minutes with hundreds of data points — isoelectric point in minutes, not an afternoon.
Concentrated, real samples
Streaming potential works up to 40 vol% with a wide charge range (±3000 mV), so you characterize the formulation as-is rather than a heavily diluted proxy.
Add in-situ size
Integrate a NANOTRAC FLEX probe into the cell to track particle size during a charge titration — making coagulation and the critical agglomeration point visible in real time.
How Additive Plus supports it
A configured, installed analyzer with a charge-titration method dialed in on your material.
Configure to your sample
We match the measuring cell, piston set and titration setup to your material, solvent and concentration before it ships.
Install & train
Factory-trained engineers install and train your team on charge titration, isoelectric-point and dispersant-optimization workflows.
Method & QC support
We build the SOP — reproducible zeta and titration reporting and, where needed, combined size-and-charge measurement with the NANOTRAC FLEX.
