SOCOREX Acura 835F Fixed-Volume Manual Pipette

Overview

The SOCOREX Acura 835F is a high-precision fixed-volume manual pipette engineered for reproducible liquid handling in regulated and high-throughput laboratory environments. Unlike adjustable-volume pipettes, the 835F series eliminates volumetric drift and operator-induced setting errors by locking the dispense volume at factory-calibrated values—2 mL, 2.5 mL, 5 mL, or 10 mL—making it ideal for routine assays, standard preparation, QC sample dilution, and reagent dispensing where volumetric consistency is critical. Built upon SOCOREX’s proven Acura platform, the 835F integrates precision fluidics with ergonomic engineering, conforming to ISO 8655-2 (volumetric accuracy requirements) and ISO 8655-5 (performance testing standards). Its all-metal piston assembly, low-friction PTFE-coated seals, and optimized air displacement architecture ensure long-term metrological stability—even after repeated autoclaving cycles.

Key Features

• Ergonomic large-area ejection button with anti-slip texture reduces thumb fatigue during high-frequency tip ejection.
• PATENTED JUSTIP™ tip ejector height adjustment (±4 mm range) ensures optimal compatibility across third-party and SOCOREX Qualitips® tips—minimizing tip wobble and seal failure.
• Front-facing digital volume display with color-coded window (distinct per volume variant) enables rapid visual identification and prevents misselection in multi-pipette workstations.
• Full-assembly autoclavability (121°C, 20 min, 1 bar) without recalibration—validated per ISO 8655-5 Annex C; no disassembly required before sterilization.
• Tool-free, user-accessible calibration system allows in-lab verification and adjustment using standard gravimetric procedures—fully traceable to NIST-traceable weights.
• Ultra-lightweight construction (88–92 g) combined with low-actuation-force piston mechanism (<1.2 N for full stroke) mitigates repetitive strain injury (RSI) risk during extended use.
• Modular design permits tool-free disassembly of the aspiration unit for thorough cleaning—critical for viscous, volatile, or biohazardous liquids.
• Volumetric lock mechanism prevents accidental volume change during operation, eliminating drift under centrifugal or vibrational conditions.

Sample Compatibility & Compliance

The Acura 835F is validated for aqueous, buffered, and mildly organic solutions (e.g., up to 30% ethanol, 15% isopropanol). Optional hydrophobic filter tips are available for applications requiring aerosol containment (e.g., PCR setup, RNA work). All variants comply with ISO 8655-2:2022 accuracy tolerances and ISO 8655-5:2022 repeatability specifications. Device documentation supports GLP and GMP workflows, including audit-ready calibration logs, maintenance records, and traceable serial-number-based certification. While not inherently 21 CFR Part 11 compliant, the pipette integrates seamlessly into validated electronic lab notebook (ELN) and LIMS environments when paired with SOCOREX-certified calibration software and controlled calibration SOPs.

Software & Data Management

The Acura 835F operates as a standalone mechanical instrument with no embedded electronics—ensuring zero firmware dependencies or cybersecurity vulnerabilities. However, its calibration data, service history, and performance verification reports can be managed via SOCOREX’s optional PipetteTrack™ Lab Manager Suite (Windows/macOS), which generates ISO/IEC 17025-compliant certificates, tracks calibration due dates, and exports CSV/PDF reports for internal QA audits. Each pipette ships with a unique serial number linked to a digital certificate of conformity, enabling full traceability from manufacturing to end-user validation.

Applications

• Preparation of calibration standards and reference materials in environmental, clinical, and pharmaceutical labs.
• Dispensing of culture media, buffers, and enzyme solutions in microbiology and cell biology workflows.
• High-reproducibility dilution series in ELISA, qPCR, and immunoassay development.
• QC release testing under USP , , and EP 2.6.17 guidelines.
• Automated workstation integration (e.g., as a fixed-dispense module in semi-automated liquid handlers).
• Teaching laboratories requiring robust, tamper-resistant instruments for student training.

FAQ

Can the Acura 835F be autoclaved without compromising accuracy?
Yes. The entire pipette—including shaft, piston, and tip cone—is designed for full-assembly autoclaving at 121°C for 20 minutes. Metrological validation confirms no measurable deviation in volume delivery post-sterilization when performed per SOCOREX’s validated protocol.
Is user calibration possible without specialized tools?
Yes. The integrated calibration dial requires only a standard analytical balance and distilled water. Adjustment is performed via a recessed screwdriver slot accessible with a supplied hex key—no external calibration station needed.
What tip types are compatible with the 835F series?
All SOCOREX Qualitips® (including low-retention, filtered, and sterile options) are fully compatible. Third-party universal-fit tips meeting ISO 8655-3:2022 dimensional tolerances may also be used, though JUSTIP™ height adjustment is recommended for optimal sealing.
Does the 835F support regulatory audit requirements?
Yes. Each unit includes a factory-issued calibration certificate with uncertainty budget, and the tool-free calibration system enables documented in-house verification—meeting core evidence requirements for ISO 17025, CLIA, and FDA inspection readiness.
How does the 835F differ from the adjustable Acura 815 series?
The 835F offers identical ergonomics, build quality, and sterilization capability—but with fixed volumes only. This eliminates volume-setting variability and reduces long-term maintenance needs, making it optimal for dedicated, high-volume tasks where volume changes are infrequent or unnecessary.
