Overview
The KEM APB-610 Semi-Automatic Burette Dispenser & Manual Titrator is an engineered solution for laboratories requiring high-fidelity manual volumetric analysis with traceable, repeatable liquid handling capabilities. Unlike fully automated titration systems, the APB-610 preserves operator control over titrant addition—critical for endpoint detection in colorimetric or potentiometric titrations where visual or electrochemical judgment determines stoichiometric equivalence. Its core architecture integrates a precision glass burette assembly with a ceramic switching valve and motorized piston drive, enabling both manual titration and programmable fixed-volume dispensing. The instrument operates on a dual-mode principle: in titration mode, the user initiates and modulates flow via foot switch or front-panel controls; in dosing mode, pre-set volumes are delivered with µL-level resolution and certified metrological performance aligned with ISO 8655-3 (volumetric apparatus — piston-operated burettes). Designed for integration into regulated environments, the APB-610 supports audit-ready workflows when paired with KEM’s AT-710 series automatic potentiometric titrators or S-BUS-compatible autosamplers.
Key Features
- Precision glass burettes available in five interchangeable volumes (1 mL to 50 mL), each calibrated and certified per ISO 8655-3 with documented accuracy, repeatability, and resolution specifications.
- PTFE-coated nozzle and dual-tip options (capillary and reverse-osmosis types) ensure compatibility with viscous, volatile, or particulate-laden reagents without clogging or carryover.
- Ceramic valve actuation provides wear-resistant, chemically inert fluid path switching between aspiration and dispensing—eliminating seal degradation common in elastomer-based systems.
- Adjustable flow rate control (0.02–60 mL/min for 20 mL burette) enables fine-tuned delivery during critical endpoint approaches, supporting USP and ASTM E200 titration methodology requirements.
- Backlit 2-line LCD display shows real-time volume, mode status, and system alerts; keyboard input and optional remote footswitch (part #12-00153-00) facilitate hands-free operation during glove use or fume hood workflows.
- Modular design allows reuse of legacy APB-410/510 burette assemblies—reducing long-term ownership cost and easing technology transition.
- Integrated leak-detection logic and drip tray containment mitigate risks from accidental overfilling or valve misalignment, satisfying IEC 61010-1 safety compliance for laboratory equipment.
Sample Compatibility & Compliance
The APB-610 accommodates a broad range of reagents—including aqueous buffers, organic solvents (e.g., ethanol, acetone), weak acids/bases, and redox titrants—without material incompatibility. All wetted surfaces consist of chemically resistant PTFE, borosilicate glass (with UV-blocking protective sleeve), and alumina ceramic—validated for exposure to pH 0–14 and common titration matrices per ISO 17025 clause 5.5.2. The instrument complies with CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), meets IEC 61010-1 safety standards for electrical equipment used in laboratory settings, and supports GLP/GMP documentation through S-BUS synchronization with KEM’s titration software, which includes electronic signature, audit trail, and 21 CFR Part 11-compliant data archiving when deployed with validated PC configuration.
Software & Data Management
While the APB-610 operates independently as a standalone burette dispenser, its full data integrity potential is realized when connected via S-BUS to KEM’s AT-710M or AT-710S automatic titrators. In this configuration, volume data is time-stamped, synchronized with electrode readings, and logged into KEM’s dedicated TitraMaster software. The software supports customizable report templates compliant with ISO/IEC 17025 reporting requirements, including uncertainty calculation per GUM (JCGM 100:2008), raw data export in CSV/TXT formats, and secure user access levels (administrator, analyst, reviewer). RS-232C connectivity enables integration with LIMS or custom SCADA systems. Temperature compensation using optional Pt100 probe ensures volumetric corrections per ISO 4787 for thermal expansion effects.
Applications
- Classical acid-base, redox, complexometric, and precipitation titrations where visual endpoint determination remains preferred (e.g., phenolphthalein in NaOH standardization, iodometry for copper assay).
- Preparation of standardized stock solutions and serial dilutions under ISO/IEC 17025 method validation protocols.
- QC testing in pharmaceutical manufacturing (e.g., assay of active ingredients per USP monographs requiring manual titration).
- Environmental water analysis (e.g., COD, alkalinity, chloride by Mohr method) where field-deployable precision and ruggedness are essential.
- Educational laboratories requiring durable, serviceable instruments that demonstrate fundamental volumetric principles without abstraction layers.
FAQ
Can the APB-610 be used without connection to an automatic titrator?
Yes—it functions fully as a stand-alone semi-automatic burette for manual titration and fixed-volume dispensing.
What burette sizes are supported, and how are they calibrated?
Five interchangeable units: 1 mL, 5 mL, 10 mL, 20 mL (standard), and 50 mL. Each is supplied with individual calibration certificate traceable to JCSS (Japan Calibration Service System) and compliant with ISO 8655-3.
Is the instrument compatible with non-KEM reagent bottles?
Yes—the fluid path accepts standard 1 L polypropylene bottles and most commercially available screw-cap reagent containers via adaptable bottle adapter kit (optional accessory).
Does the APB-610 support temperature compensation during titration?
Yes—when equipped with the optional Pt100 temperature sensor (connected via dedicated port), volume data is automatically corrected for thermal expansion per ISO 4787 Annex C.
What maintenance is required for long-term accuracy?
Annual verification of burette accuracy using certified reference weights and water density tables is recommended; ceramic valve and PTFE components require no lubrication and exhibit >100,000-cycle service life under normal usage.
