How to choose an automatic titrator
Start from the chemistry, not the brochure. Match the reaction type to the electrode and titrant, then size the system for your daily throughput and documentation (GLP/GMP / data integrity) needs:
| Reaction / application | Typical electrode | Notes |
|---|---|---|
| Acid–base (aqueous) | Glass pH | most common QC method |
| Non-aqueous acid–base (TAN/TBN) | glass + non-aqueous reference | oils, fuels |
| Redox | platinum | iodometric, permanganate |
| Chloride / precipitation | silver | food salt, water |
| Water content | KF double-Pt | volumetric / coulometric |
Choosing the system tier
| Tier | Best for |
|---|---|
| Compact single-titrant | routine single-method QC, low throughput |
| Advanced multi-titrant | several methods / higher precision |
| With autosampler | high daily throughput, unattended runs |
A complete solution — not just a box
BioAnalytics takes responsibility for the result across the instrument's life: instrument + electrode selection · method development & transfer · on-site installation & training · technical service · ISO 17025-accredited calibration. A titrator is only as good as its electrode, method and upkeep — which is why the lifecycle matters more than the model.
