About Potentiometric Titrator Optional 21 CFR Part 11

Automatic Potentiometric Titrator

Product Description

The Veego Automatic Potentiometric Titrator (AUTO/POT-I) is a microcontroller-based automatic titration system designed for accurate potentiometric analysis in quality control, research and analytical laboratories. The instrument is available in two configurations: a Standard Model for routine laboratory applications and an optional 21 CFR Part 11 Compliant Model (AUTO/POT-I CF) for pharmaceutical and regulated laboratories requiring electronic records, audit trails and user access control. Both configurations share the same hardware platform, with the CFR model providing additional compliance software features.

The AUTO/POT-I automatically determines the titration endpoint by measuring the potential developed between the indicator and reference electrodes while accurately dispensing the titrant through its maintenance-free metering dispenser. The instrument supports aqueous, non-aqueous and redox titrations, along with single, double and multi-peak titration, making it suitable for a wide range of analytical applications across pharmaceutical, chemical and industrial laboratories.

Designed for routine laboratory efficiency, the instrument stores 100 test methods, supports standard sample and volumetric normality calculations, and features an informative LCD backlit graphic display with both feather-touch keypad and external QWERTY keyboard. It also includes printer connectivity, balance interface and PC communication through the Titration Monitor software. Laboratories requiring regulatory compliance can choose the 21 CFR Part 11 version, which adds role-based user management, electronic authentication, audit trails, Ethernet connectivity and secure electronic record management without changing the instrument's hardware.

Frequently Asked Questions

What is the Veego Automatic Potentiometric Titrator used for?

The AUTO/POT-I is used for automatic potentiometric titrations including aqueous, non-aqueous, redox, TAN/TBN, assay determination, chloride analysis, EDTA titrations, iodine number, saponification number and several other analytical applications in QC, QA and R&D laboratories.

Is this instrument available with 21 CFR Part 11 compliance?

Yes. The AUTO/POT-I is available in both a Standard configuration and a 21 CFR Part 11 Compliant configuration (AUTO/POT-I CF). The hardware remains the same, while the compliant version adds software features such as role-based access control, audit trail, electronic authentication, Ethernet connectivity and secure user management.

What types of titration does the instrument support?

The instrument supports aqueous, non-aqueous and redox titrations, together with single, double and multi-peak titration modes. It also provides standard sample and volumetric methods for normality determination.

How many methods can be stored?

The AUTO/POT-I stores 100 test methods, allowing laboratories to save and recall frequently used analytical procedures.

Does the instrument support printer and PC connectivity?

Yes. The standard model includes a dot matrix printer interface, RS-232 balance interface and PC communication through the Titration Monitor software. The 21 CFR Part 11 version additionally provides Ethernet connectivity for secure data management.

What additional features are included in the 21 CFR Part 11 version?

The compliant version includes four user levels, role-based access control, user management, configurable password policies, authentication with date and time stamps, backup and restore facilities, print tracking and a non-editable audit trail to support laboratories operating under regulatory requirements.

Which industries commonly use this instrument?

The AUTO/POT-I is widely used in pharmaceutical, chemical, petrochemical, food, research and industrial laboratories performing routine analytical titrations, quality control and quality assurance testing. The brochure specifically identifies QC, QA and R&D laboratory applications.
