Product overview
The Nittoseiko Analytech Automatic Titrator pairs a high-precision buret with an advanced titration control method for consistent results.
Titration accuracy really comes down to two things: how precisely the buret dispenses, and how well the control method reads the endpoint. As a trusted Automatic Titrator supplier across the UAE, Saudi Arabia, Qatar, Kuwait, Oman, and Bahrain, we built this system around both of those problems. The automatic buret is high-precision by design, and it’s paired with a newer titration control method that keeps results consistent run after run, which is really what anyone shopping for an automatic titrator is actually looking for.
The practical upside for busy labs is the multi-unit setup: up to four units can be connected and run at the same time. Instead of queuing samples one after another, a lab can have several titrations going in parallel, whether that’s potentiometric work like acid-base, redox, chelatometric, and precipitation titrations, or Karl Fischer moisture determination running alongside them. That’s the kind of flexibility that separates a genuinely useful karl fischer titrator from one that just checks a box on a spec sheet.
ASTM E203, Karl Fischer Methods
Most labs working with a karl fischer titration instrument already know ASTM E203 by heart, it’s the standard reference for water determination by Karl Fischer titration, and this system is built to comply with it directly, no workarounds needed.
4-channels titration:
You can connect up to four potentiometric and Karl Fischer titrators to one Multi-controller and run them all at once. For a lab pushing through a steady stream of samples, that’s less time waiting around and more time actually getting through the day’s work.
Automatic pH calibration:
The system includes an automatic stability judgement function, so it knows when a reading has settled. Add the MST sampler into the mix and the entire process, calibration through to final sample measurement, can run on its own.
Reanalysis function:
Not every endpoint method gives the cleanest answer on the first try. This one lets you go back and reanalyze, switching between inflection point, set potential, front intersection, rear intersection, or V intersection, without having to redo the titration from scratch.
LIMS connection:
As measurements come in, the Multi-controller pushes that data straight to the network. It’s a small thing, but it saves a fair amount of manual entry and the transcription errors that tend to come with it.
Data Integrity:
The GT-310 has data integrity built right in, so labs get solid data protection and management without needing to run a dedicated PC alongside it. If an audit trail is required, that’s available as an add-on within the data integrity version of the GT-310 software.

This automatic titration machine shows up in labs across a fairly wide spread of industries:
- Petrochemicals
- Oil, power, and energy
- Food and beverages
- Pharmaceuticals and cosmetics
- Chemical manufacturing
- Plastics and rubber
Anywhere moisture content or acid-base balance needs to be measured with real precision and repeated reliably, this kind of auto titration equipment tends to earn a permanent spot on the bench, whether that’s day-to-day QC work or something closer to method development.
