The Thermo Scientific™ Orion Star™ T940 All-in-One Titrator is a versatile automated titration system designed to perform acid–base, redox, and ion concentration titrations using a single instrument platform. By integrating Thermo Scientific’s proven electrochemistry technology with a precision automated dispensing system, the T940 simplifies titration workflows while delivering accurate, reproducible, and consistent analytical results.

This advanced titrator automates the entire titration process—from method setup and calibration to titration and result documentation—making it significantly more reliable and efficient than traditional manual titration techniques. The system allows laboratories to store methods, automate calculations, and run titrations unattended, thereby improving productivity and reducing operator variability.

The Orion Star T940 is widely used in environmental testing, food and beverage analysis, chemical laboratories, pharmaceutical quality control, and academic research, where precise measurement of acidity, oxidation-reduction potential, and ionic concentration is required.

Key Features

All-in-One Titration Platform

The Orion Star T940 supports multiple titration types within a single instrument:

• Acid-base titrations
• Redox titrations
• Ion concentration titrations using ion selective electrodes (ISE)

This flexibility eliminates the need for multiple titration instruments.

Flexible Titration Techniques

The instrument supports several analytical titration methods:

• Equivalence point titrations (1–2 equivalence points)
• Preset pH or mV endpoint titrations (1–3 endpoints)
• Multiple Known Addition (MKA) mode

The MKA technique performs automated calibration and concentration calculation by adding aliquots of standard solution directly to the sample, reducing matrix effects and eliminating the need for separate calibration procedures.

Automated Workflow

Automating titration workflows ensures:

• Consistent setup parameters and calculations
• Improved reproducibility
• Reduced operator errors
• Higher laboratory throughput

Once a method is created, users can run repeated analyses using the same stored parameters.

Precision Dispensing System

The integrated burette drive uses advanced micro-step motor technology:

• 25,600 micro-steps per motor revolution
• Over 2 million micro-steps across the full burette stroke

This allows smooth and highly accurate titrant dispensing, improving titration precision.

Large Color Touchscreen Interface

The instrument features a 5.7-inch capacitive color touchscreen display (640 × 480 resolution) that provides:

• Real-time titration curves
• Guided setup instructions
• Onscreen help menus
• Clear result visualization

Method Programming and Data Management

The Orion Star T940 allows users to:

• Create and save up to 10 titration methods
• Import/export methods via USB flash drive
• Password-protect methods for secure operation

The instrument stores 100 data sets each for:

• Sample titration
• Titrant standardization
• Calibration
• Direct measurements

Data can be exported as CSV or PDF files for reporting or integration with laboratory data systems.
