Overview
The A&D MPA-1200 is a precision-engineered single-channel electronic pipette designed for high-reproducibility liquid handling in regulated laboratory environments—including clinical diagnostics, pharmaceutical QC, academic research, and biotechnology development. Operating on motor-driven piston displacement principles, the MPA-1200 delivers consistent aspiration and dispensing across its full 100–1200 µL range without mechanical wear associated with manual thumb operation. Its closed-loop feedback system continuously monitors plunger position and motor torque, enabling real-time compensation for viscosity variations and ambient temperature fluctuations—critical for maintaining metrological integrity during serial dilutions or reagent preparation. Unlike pneumatic-only systems, the MPA-1200 integrates pressure-sensing logic to detect tip seal integrity prior to aspiration, reducing volume deviation caused by partial tip leakage.
Key Features
- Four programmable dispensing modes: Standard Pipetting, Multiple Dispensing (up to 99 repetitions), Mixing (aspirate/dispense cycles within same tip), and Reverse Pipetting—optimized for viscous, volatile, or foaming liquids.
- Ergonomic soft-touch control buttons with tactile feedback minimize finger fatigue and reduce risk of repetitive strain injury (RSI) during extended use sessions.
- One-step tip attachment mechanism ensures gas-tight sealing without manual compression; compatible with universal low-retention and filtered tips (DNase/RNase-free certified options available).
- Impact-resistant LCD display with anti-scratch coating and shock-absorbing housing meets IEC 60529 IP54 specifications for dust and splash resistance.
- Integrated rechargeable lithium-ion battery supports ≥10,000 pipetting cycles per full charge (typical usage); USB-C port enables rapid top-up (<30 min for 80% capacity) without removing the battery.
- On-device calibration capability includes both gravimetric (weight-based) and volumetric (density-corrected) protocols, traceable to NIST-traceable standards—enabling compliance with ISO 8655-6 and CLSI EP15-A3 requirements.
Sample Compatibility & Compliance
The MPA-1200 handles aqueous buffers, cell culture media, ethanol solutions (up to 70%), glycerol-containing reagents (≤30% v/v), and diluted protein samples without performance degradation. All wetted components are chemically inert (polypropylene, PTFE-coated stainless steel piston), ensuring compatibility with common laboratory solvents and preventing carryover contamination. The device conforms to ISO 8655-1 (general requirements), ISO 8655-2 (volumetric performance), and ISO 8655-5 (calibration procedures). It supports GLP/GMP documentation workflows through user-accessible audit logs that record calibration events, date/time stamps, operator ID (via optional RFID badge integration), and environmental metadata (ambient temperature/humidity if paired with external sensor modules).
Software & Data Management
While fully functional as a standalone instrument, the MPA-1200 supports optional PC connectivity via USB-C for firmware updates and advanced configuration using A&D’s Pipette Manager Suite (Windows/macOS). This software enables export of calibration reports in PDF/XLSX formats compliant with FDA 21 CFR Part 11 Annex 11 requirements—including electronic signatures, version-controlled parameter histories, and immutable audit trails. Data export includes raw gravimetric measurements, calculated volume deviations, uncertainty budgets, and pass/fail status against user-defined acceptance criteria aligned with ISO/IEC 17025 clause 7.7.
Applications
- Preparation of standard curves and serial dilutions in ELISA, qPCR, and immunoassay workflows.
- Accurate dispensing of transfection reagents, CRISPR-Cas9 components, and lipid nanoparticles in gene editing applications.
- QC testing of raw materials and finished products under USP , , and guidelines.
- High-throughput sample normalization in metabolomics and proteomics sample preparation pipelines.
- Calibration verification of automated liquid handlers (e.g., Tecan Freedom EVO, Hamilton STAR) using gravimetric reference methods per ISO/IEC 17025.
FAQ
Does the MPA-1200 support regulatory-compliant calibration documentation?
Yes—it generates timestamped, operator-identified calibration records with traceability to mass standards, satisfying ISO 8655-6 and FDA 21 CFR Part 11 requirements when used with Pipette Manager Suite.
Can it be calibrated for non-aqueous liquids like DMSO or glycerol?
Yes—the volumetric calibration mode applies density correction factors entered manually or imported from built-in solvent tables, ensuring accuracy for density-adjusted dispenses.
Is tip ejection force adjustable?
No—ejection force is fixed at 12 N to ensure reliable tip release across all certified tip brands while preventing damage to rack inserts or plate wells.
What is the recommended recalibration interval?
A&D recommends quarterly calibration for routine use; more frequent verification (e.g., daily gravimetric checks) is advised in GxP environments per internal SOPs or risk assessments.
Are service manuals and spare parts available internationally?
Yes—A&D provides English-language technical documentation, certified repair centers in EMEA/APAC/NA regions, and 24-month warranty coverage inclusive of labor and components.
