Sartorius SpeedCal Mobile Multi-Channel Pipette Calibration System

Overview

The Sartorius SpeedCal Mobile Multi-Channel Pipette Calibration System is an engineered solution for high-throughput, gravimetric calibration of multi-channel liquid handling instruments in compliance with ISO 8655-6 (2022) and ISO/IEC 17025 requirements. It employs precision mass measurement via synchronized, traceable load cells to determine dispensed volume based on the density-corrected mass-to-volume conversion principle (ρ = m/V). Unlike manual or single-channel gravimetric methods, SpeedCal Mobile eliminates sequential channel testing by acquiring real-time mass data from up to twelve independently calibrated sensors simultaneously—enabling full 12-channel verification in under eight minutes. Its modular architecture supports both fixed-laboratory integration and mobile deployment, making it suitable for centralized QC labs, contract testing facilities, and field-based instrument service teams operating under strict regulatory timelines.

Key Features

• Simultaneous 4-, 8-, or 12-channel calibration using parallel high-stability load cells with internal temperature compensation and automatic zero-tracking
• Integrated transport enclosure with shock-absorbing mounts, dust-resistant seals, and integrated power management for uninterrupted operation at remote sites
• Modular sensor bay design allows field upgrade from 4- or 8-channel configurations to full 12-channel capability without hardware replacement
• Real-time gravimetric data acquisition at ≥10 Hz sampling rate, synchronized across all channels with timestamped metadata (date, operator ID, ambient T/RH)
• On-device validation routines including linearity checks, repeatability assessment (n ≥ 10), and drift monitoring per ISO 8655-6 Annex C
• Compliance-ready output formats: PDF calibration certificates with uncertainty budgets, CSV raw datasets, and XML exports compatible with LIMS and ELN systems

Sample Compatibility & Compliance

SpeedCal Mobile accommodates standard multi-channel pipettes ranging from 1 µL to 1,250 µL nominal volumes, including positive-displacement and air-displacement types with tip geometries conforming to ISO 8655-2 specifications. It supports calibration using Class A distilled water (density certified per ISO 4787) or user-defined fluids with known density and viscosity profiles. The system meets the metrological requirements of ISO 8655-6 for multi-channel pipette verification, including channel-to-channel deviation limits, within-channel repeatability thresholds, and systematic error quantification. All measurements are traceable to national standards (e.g., PTB, NIST) via factory-certified load cell calibrations. Audit trails comply with FDA 21 CFR Part 11 and EU Annex 11 when paired with validated Sartorius LabX software.

Software & Data Management

The SpeedCal Mobile operates with Sartorius LabX Pipette Calibration Module—a validated application supporting role-based access control, electronic signatures, and full ALCOA+ data integrity principles. Calibration protocols are preconfigured according to ISO 8655-6 test sequences (e.g., single-point, multi-point, reverse pipetting), with automatic pass/fail evaluation against user-defined acceptance criteria. Raw mass data undergoes real-time density correction using measured ambient temperature and humidity inputs. All reports include expanded uncertainty calculations (k=2), measurement uncertainty contributors (load cell resolution, evaporation loss, density variability), and instrument-specific calibration history. Data export supports direct integration into enterprise quality management systems (QMS) and electronic lab notebooks (ELNs) via secure API or SFTP.

Applications

• High-volume routine calibration of multi-channel pipettes in pharmaceutical QC laboratories performing batch release testing
• Field service operations for CROs and instrument service providers requiring rapid turnaround at client sites
• Method qualification and verification of automated liquid handlers prior to GxP-compliant assay implementation
• Internal audit preparation and regulatory inspection readiness for FDA, EMA, or PMDA assessments
• Training and competency assessment of laboratory personnel in pipette handling and calibration best practices
• Supporting ISO/IEC 17025 accreditation maintenance through documented traceability and measurement uncertainty reporting

FAQ

Does SpeedCal Mobile require external PC connectivity to perform calibration?
No—it operates as a standalone system with embedded computing; optional LabX connectivity enhances data management but is not required for core calibration functionality.
Can the system calibrate both forward and reverse pipetting modes?
Yes—predefined test sequences in LabX support both delivery and blow-out modes per ISO 8655-6 Annex D.
Is evaporation correction applied automatically during measurement?
Yes—real-time environmental monitoring enables dynamic evaporation loss estimation using the ISO 8655-6 recommended model.
What documentation is generated upon completion of a calibration run?
A compliant PDF certificate, raw data file (CSV), and XML report containing all metadata, uncertainty components, and operator-signed approval fields.
How frequently must the load cells be recalibrated?
Factory calibration is valid for 12 months under normal use; annual third-party verification against accredited mass standards is recommended for GLP/GMP applications.
