Overview
The HengAo HDS-06 Fully Automated Sample Dilutor is an integrated liquid handling platform engineered for precision, repeatability, and traceability in quantitative dilution workflows. It operates on a positive-displacement piston-driven fluidics architecture, ensuring minimal carryover and high volumetric accuracy across serial and parallel dilution schemes. Designed for laboratories requiring strict adherence to analytical pre-treatment protocols—particularly in environmental testing, clinical chemistry, pharmaceutical QC, and food safety analysis—the system automates the entire dilution process from stock solution aspiration through multi-step diluent addition, mixing, and final aliquot dispensing. Its closed-system design minimizes operator exposure and ambient contamination, while built-in calibration verification routines support routine performance qualification per ISO/IEC 17025 and GLP requirements.
Key Features
- Fully programmable dilution matrix: supports up to 6 independent dilution steps with variable ratios (1:2 to 1:10,000) and customizable volume increments (10 µL–5 mL per step)
- Integrated dual-channel syringe pumps with ceramic-coated pistons and PTFE-sealed valves for chemical compatibility with aqueous, organic, and mildly acidic/basic solutions
- Onboard barcode scanner for sample tube identification and audit-trail linkage to LIMS or ELN systems
- Real-time pressure monitoring and air bubble detection to prevent incomplete aspiration or dispensing failures
- Self-cleaning fluid path with configurable rinse cycles (water, ethanol, or user-defined wash solvents) between samples
- Touchscreen HMI with intuitive workflow builder; supports method import/export via USB or Ethernet
Sample Compatibility & Compliance
The HDS-06 accommodates standard 12–16 mm diameter tubes (e.g., 13 × 100 mm glass or polypropylene), 96-well microplates (flat, V-bottom, or round-bottom), and custom vial formats via adjustable carrier trays. All wetted materials—including fluidic pathways, seals, and dispensing tips—are certified non-leaching and compliant with USP Class VI and FDA 21 CFR Part 11 for electronic records and signatures. The instrument meets electromagnetic compatibility (EMC) standards per IEC 61326-1 and safety requirements under IEC 61010-1. Routine operation aligns with ISO 8655-5 (volumetric accuracy of piston-operated instruments) and supports validation documentation packages for GMP/GLP audits.
Software & Data Management
The embedded firmware includes a validated control software suite with role-based user access (administrator, technician, reviewer), full electronic audit trail (timestamped events, parameter changes, error logs), and automatic data export in CSV or XML format. Optional integration with laboratory information management systems (LIMS) is supported via HL7 or ASTM E1384-compliant interfaces. All dilution methods are digitally signed and version-controlled; method revisions trigger automatic requalification prompts. Data integrity safeguards include forced password rotation, session timeout, and immutable log archiving—enabling compliance with FDA 21 CFR Part 11 Subpart B for electronic records and electronic signatures.
Applications
- Preparation of calibration standards for ICP-MS, AAS, and UV-Vis spectrophotometry
- Dilution of wastewater, soil leachate, or biological matrices prior to EPA Method 200.8 or ISO 17294-2 analysis
- QC sample conditioning for pharmacopeial assays (USP , EP 2.2.46)
- Automated serial dilution for microbiological colony-forming unit (CFU) enumeration per ISO 7218
- Standardization of reference materials in metrology labs accredited to ISO/IEC 17025
FAQ
What is the minimum and maximum dilution volume achievable per step?
The system delivers precise volumes from 10 µL to 5 mL per individual dilution step, with cumulative dilution factors up to 1010 across six sequential stages.
Does the HDS-06 support unattended overnight operation?
Yes—equipped with watchdog timers, low-reagent alerts, and automatic shutdown upon completion or fault detection, it is validated for extended batch runs without manual intervention.
Can third-party pipette tips or consumables be used?
Only HengAo-certified disposable tips and reservoirs are supported to maintain volumetric accuracy and ensure compliance with ISO 8655-5 calibration traceability.
Is IQ/OQ/PQ documentation available?
A complete validation package—including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) protocols and reports—is provided with each unit and may be customized for site-specific regulatory requirements.
How often does the system require recalibration?
Calibration verification is recommended before each analytical batch using gravimetric or photometric reference standards; full recalibration is required annually or after maintenance affecting fluidic components.
