Overview
The Drick DRK-DT8 is a dual-channel automatic potentiometric titrator engineered for precision volumetric analysis in regulated and research-intensive laboratory environments. It operates on the fundamental principle of potentiometry—measuring the potential difference between a reference electrode and an indicator electrode as a function of titrant addition—to identify stoichiometric endpoints with high reproducibility. Designed for universal application, the DRK-DT8 supports acid-base, redox, precipitation, and complexometric titrations without hardware modification. Its dual-channel architecture enables simultaneous or sequential titration of two independent samples or parallel method validation—critical for QC labs operating under GLP or ISO/IEC 17025 frameworks. The instrument integrates a high-stability analog front-end with low-noise signal conditioning, ensuring stable baseline response across extended measurement ranges.
Key Features
- Dual independent titration channels with fully synchronized or decoupled operation modes
- Extended electrochemical measurement range: −2000.0 mV to +2000.0 mV and pH −20.000 to +20.000—suitable for non-aqueous, highly alkaline, or strongly acidic matrices
- High-resolution detection: 0.1 mV potential resolution and 0.001 pH resolution, supporting precise endpoint discrimination in low-slope titration curves
- Accuracy certified at ±0.1 mV and ±0.002 pH under controlled calibration conditions per ASTM E2087 and ISO 8655-6
- Modular electrode interface accommodating glass, combination, ion-selective, and redox electrodes with automatic recognition via digital ID tags (optional)
- Integrated burette drive with micro-stepping motor control and gravimetric verification capability (add-on module)
- Robust mechanical architecture with corrosion-resistant fluid path components compliant with IEC 61000-6-2 EMC standards
Sample Compatibility & Compliance
The DRK-DT8 accommodates a broad spectrum of sample types—including aqueous solutions, ethanol/water mixtures, acetonitrile-based solvents, and viscous oils—when paired with appropriate electrode configurations and solvent-compatible tubing. It meets essential regulatory prerequisites for routine testing in food safety (AOAC 984.27), pharmaceutical assay (USP ), water quality (EPA 300.0), and industrial chemical QC. While not pre-certified for FDA 21 CFR Part 11 out-of-the-box, the system supports audit trail logging, electronic signature integration, and user access control when deployed with validated third-party LIMS or ELN platforms. All firmware and method storage adhere to data integrity principles aligned with ALCOA+ guidelines.
Software & Data Management
The DRK-DT8 is operated via Drick TitrSoft v3.x—a Windows-based control and analysis suite supporting method creation, real-time curve visualization, derivative peak detection, and customizable reporting templates. Raw data files are saved in vendor-neutral CSV and XML formats, enabling traceable export to statistical process control (SPC) tools or enterprise QA databases. The software includes built-in compliance features such as operator login with role-based permissions, method versioning, and timestamped audit logs for all critical actions—including calibration, titration start/stop, and result approval. Optional GxP-ready modules provide electronic signature enforcement, change control tracking, and automated backup to network drives compliant with ISO 27001 information security policies.
Applications
- Determination of total acidity and free fatty acids in edible oils and biodiesel (ASTM D664, EN 14104)
- Chloride quantification in drinking water and wastewater by argentometric titration (ISO 9297)
- Calcium and magnesium hardness profiling in industrial cooling water systems
- Active pharmaceutical ingredient (API) assay via non-aqueous acidimetry (USP )
- Titratable alkalinity in geological leachates and soil extracts
- Redox titration of iron(II) in ore concentrates using cerimetric or permanganometric methods
- Validation of buffer capacity and pKa values in formulation development laboratories
FAQ
Does the DRK-DT8 support GLP-compliant data archiving?
Yes—when configured with TitrSoft’s optional Audit Trail Module and deployed on a domain-controlled Windows environment, it satisfies core GLP requirements for data traceability, operator accountability, and method version control.
Can the instrument perform thermometric or conductometric titrations?
No—the DRK-DT8 is exclusively a potentiometric platform. Thermometric and conductometric capabilities require dedicated hardware sensors and are not supported by this model.
Is remote monitoring or cloud-based data synchronization available?
Native cloud sync is not implemented; however, CSV/XML exports can be ingested into cloud-hosted LIMS or ELN systems via scheduled FTP/SFTP scripts or API middleware integrations.
What electrode calibration protocols are supported?
Two-point and multi-point calibration for pH and mV modes per ISO 7027 and IUPAC recommendations; automatic slope and offset validation before each titration sequence.
Are service contracts and extended warranty options available internationally?
Yes—Drick offers global technical support through authorized regional partners, including on-site calibration, preventive maintenance plans, and firmware upgrade subscriptions aligned with IEC 62304 lifecycle management standards.
