SOCOREX Acura® 815 Fixed-Volume Manual Pipette

Overview

The SOCOREX Acura® 815 Fixed-Volume Manual Pipette is a precision-engineered liquid handling instrument designed for high-reproducibility dispensing in regulated laboratory environments. Unlike adjustable-volume pipettes, the 815 series features factory-set, non-adjustable volume mechanisms—eliminating user-induced volumetric drift and ensuring long-term metrological stability. Each variant is calibrated and certified to ISO 8655-2:2022 (Piston-operated volumetric apparatus — Part 2: Piston pipettes) and traceable to NIST or PTB standards. The device operates on air displacement principle, utilizing a corrosion-resistant stainless-steel piston sealed with fluoropolymer O-rings to maintain consistent aspiration and dispensing dynamics across temperature and humidity gradients. Its fixed-volume architecture is particularly suited for high-throughput applications where volumetric consistency, operator training minimization, and audit-ready documentation are critical—such as QC release testing, clinical diagnostics workflows, and reference material preparation under GLP/GMP conditions.

Key Features

• Full autoclavability: Entire unit withstands 121°C, 20-minute steam sterilization without calibration drift or structural compromise—validated per ISO 17664.
• Ergonomic design: Weighing only 88–92 g with ultra-low plunger activation force (<1.2 N), reducing repetitive strain risk during extended use.
• Large-area anti-slip ejection button: Optimized tactile feedback and mechanical advantage for effortless tip ejection—even with gloved hands.
• JUSTIP™ adjustable ejector rod: >4 mm vertical adjustment range ensures optimal engagement with diverse tip brands (including low-retention, filter, and universal-fit variants).
• Volume-specific color coding: Digit display window and top cap use standardized chromatic identifiers (e.g., blue for 10–100 µL, green for 200–1000 µL) to prevent volume misselection—a critical visual control in multi-user labs.
• Tool-free recalibration system: Internal adjustment screw accessible via removable end cap; enables user-performed verification and fine-tuning without disassembly or external service tools.
• Modular construction: Piston assembly, sleeve, and nozzle can be fully disassembled using standard lab tools for deep cleaning or replacement—no adhesives or permanent bonding used.
• Integrated volume lock: Top dial incorporates mechanical detent and friction brake to prevent inadvertent volume shift during transport or handling.

Sample Compatibility & Compliance

The Acura® 815 is compatible with all major OEM and third-party pipette tips meeting ISO 8655-3 dimensional tolerances—including SOCOREX Qualitips®, low-binding polypropylene tips, and filtered barrier tips. Tip fit validation includes axial force testing (≤2.5 N insertion force) and seal integrity assessment (vacuum hold ≥30 s at –10 kPa). Regulatory compliance extends to FDA 21 CFR Part 11 (when paired with validated electronic log systems), EU Annex 11, and ISO/IEC 17025:2017 requirements for measurement traceability. Each unit ships with a Certificate of Conformance listing individual serial number, tested volume points, accuracy/precision data, and calibration date—fully compliant with internal audit and regulatory inspection protocols.

Software & Data Management

While the 815 is a manual instrument, its calibration history and performance verification records integrate seamlessly into laboratory quality management systems (QMS). SOCOREX provides downloadable PDF calibration templates aligned with ISO/IEC 17025 Annex A.3 and GxP Annex 15 requirements, supporting electronic signature capture, revision control, and retention periods ≥5 years. Optional digital calibration logs—generated via SOCOREX-certified service centers—include timestamped metrology reports with uncertainty budgets (k=2), environmental condition logging (temperature/humidity), and technician accreditation details. All documentation supports full traceability from pipette serial number to national metrology institute (NMI) reference standards.

Applications

• Pharmaceutical QC: Accurate dispensing of standards, controls, and samples in HPLC, dissolution, and microbial limit testing per USP , , and .
• Clinical microbiology: Reproducible inoculation of agar plates, broth dilutions, and MALDI-TOF sample spotting—reducing inter-operator variability in CLIA-certified labs.
• Genomics: Precise loading of PCR master mixes, restriction digests, and NGS library normalization steps where volume fidelity directly impacts assay sensitivity.
• Reference material preparation: Certified reference solution aliquoting under ISO Guide 34 and ISO/IEC 17034 requirements.
• Educational laboratories: Teaching metrological principles—accuracy vs. precision, systematic error sources, and calibration hierarchy—using physically stable fixed-volume references.

FAQ

Is the entire pipette body autoclavable without recalibration?
Yes. The Acura® 815 is validated for full-unit autoclaving at 121°C for 20 minutes (EN 285, ISO 17664), with post-sterilization accuracy deviation within ±0.1% of nominal volume.
Can I use non-SOCOREX tips with the 815 series?
Yes—provided tips comply with ISO 8655-3 geometry specifications. JUSTIP™ adjustability accommodates tip length variations up to ±2.1 mm.
What documentation accompanies each unit?
Each pipette ships with a Certificate of Conformance (CoC), factory calibration report, ISO 8655 traceability statement, and user manual with maintenance schedule and verification procedures.
How often should routine verification be performed?
Per ISO 8655-5 and CLSI EP15-A3, daily volumetric verification is recommended for critical applications; weekly for general use. Full recalibration is advised annually or after 10,000 cycles.
Does the 3-year warranty cover calibration drift?
Yes—the warranty includes free recalibration and repair for any performance deviation exceeding ISO 8655-2 tolerance limits, provided the unit has been maintained per SOCOREX guidelines.
