The ConductScience Automatic Titrator is a precision analytical instrument designed for quantitative chemical analysis across multiple titration modes. This benchtop system delivers 0.001ml volume accuracy with comprehensive titration capabilities including acid-base, redox, precipitation, complexation, and non-aqueous titrations. The instrument features an integrated PC control system with dedicated software, built-in liquid filling unit, and expandable 8-channel architecture for high-throughput sample processing.
The system incorporates interchangeable burette configurations (1ml to 50ml capacity with 10ml standard), temperature monitoring from -5°C to 120°C with ±0.1°C accuracy, and multiple connectivity options including USB, RS232, and Ethernet interfaces. Compatible with GT robot injection systems for automated sample handling, the titrator provides standardized analytical workflows for research laboratories requiring precise endpoint determination and volumetric analysis across diverse chemical systems.
How It Works
Automatic titration operates through controlled addition of titrant solution to an analyte sample while continuously monitoring the system response through potentiometric, conductometric, or photometric detection methods. The instrument's precision burette system delivers measured volumes of titrant with 1/1500,000 resolution while integrated sensors track changes in electrical potential, conductivity, or optical properties to identify the equivalence point where stoichiometric neutralization occurs.
The system's built-in liquid filling unit maintains consistent titrant delivery across the 8-channel architecture, while temperature compensation algorithms account for thermal effects on reaction kinetics and electrode response. Automated endpoint detection algorithms analyze derivative curves and inflection points to determine precise equivalence volumes, calculating analyte concentrations based on titrant molarity and stoichiometric relationships.
PC-based control software manages titration parameters, data acquisition, and result calculations while providing real-time monitoring of titration curves and system status. The instrument's self-checking function validates burette accuracy, electrode response, and temperature calibration before each analytical sequence to ensure measurement reliability.

Practical Tips
Perform burette accuracy verification using certified Class A volumetric standards at multiple volume points across the selected burette range.
Why: Multi-point calibration ensures accuracy across the entire operational volume range and identifies potential systematic errors.
Clean liquid pathways with appropriate solvents after each analytical session and store electrodes in recommended maintenance solutions.
Why: Regular cleaning prevents reagent buildup and electrode contamination that can affect endpoint detection accuracy.
Allow the system to temperature equilibrate for 30 minutes before critical analyses and use consistent stirring parameters across sample sets.
Why: Thermal stability and standardized mixing conditions minimize variability in endpoint detection and improve measurement reproducibility.
Monitor titration curve derivatives and inflection point sharpness to assess endpoint detection quality and method suitability.
Why: Curve analysis provides real-time feedback on method performance and helps identify samples requiring analytical protocol adjustments.
Check burette refill performance and liquid pathway continuity if volume delivery accuracy deviates from specifications.
Why: Air bubbles or partial blockages in the filling system can cause volume delivery errors that compromise analytical accuracy.
Ensure proper ventilation when performing non-aqueous titrations and use appropriate personal protective equipment for reagent handling.
Why: Organic solvents and concentrated reagents require adequate ventilation and safety precautions to prevent exposure risks.

Compliance
What calibration standards are required for endpoint detection accuracy?
The system requires certified buffer standards for pH electrode calibration and standardized titrant solutions with known molarity. Temperature compensation is verified using thermometric standards across the -5°C to 120°C operational range.
Can the instrument handle viscous or non-aqueous sample matrices?
Yes, the titrator specifically supports non-aqueous titration modes and accommodates diverse sample matrices through adjustable stirring parameters and specialized electrode configurations for organic solvents.
How does the 8-channel system manage cross-contamination between samples?
Each channel operates independently with dedicated liquid pathways and individual method control. Automated rinsing protocols and separate electrode assemblies prevent cross-contamination in multi-sample workflows.
What data output formats are supported for laboratory information systems integration?
The PC control software provides multiple connectivity options including USB, RS232, and Ethernet interfaces with customizable data export formats. Consult product datasheet for specific LIMS compatibility protocols.
How frequently does the burette system require recalibration?
Burette accuracy should be verified monthly using certified volumetric standards or when the self-checking function indicates calibration drift. The 1/1500,000 resolution requires stable environmental conditions for optimal performance.
What maintenance procedures are required for the built-in filling unit?
Regular cleaning with compatible solvents and periodic seal replacement maintain filling unit performance. The 10-second refill capability requires clean liquid pathways and proper vacuum system maintenance.
Can the system be integrated with robotic sample handling equipment?
Yes, the titrator is compatible with GT robot injection systems for automated sample introduction and high-throughput analysis workflows. Integration requires coordination of communication protocols and sample positioning.
How does temperature variation affect endpoint detection sensitivity?
