DLAB dPette SCAA-105 Single-Channel Electronic Pipette

Overview

The DLAB dPette SCAA-105 is a single-channel electronic pipette engineered for precision liquid handling in routine laboratory workflows where reproducibility, ergonomic efficiency, and operational flexibility are critical. Unlike fully automated liquid handlers or traditional air-displacement manual pipettes, the SCAA-105 employs a brushless stepper motor coupled with a high-tolerance piston assembly to deliver consistent volumetric delivery across its primary calibrated range of 0.5–10 µL. Its hybrid design bridges the tactile familiarity of manual pipetting—retaining low mass (≤110 g), balanced center-of-gravity positioning, and intuitive thumb-actuated controls—with the metrological advantages of electronic actuation: reduced operator-induced variability, programmable volume recall, and repeatable aspiration/dispense kinetics. The device operates on a rechargeable lithium-ion battery system, supporting both cradle-based and direct USB-C charging—ensuring uninterrupted operation in GLP-compliant environments where instrument uptime and traceable power management are essential.

Key Features

• High-resolution stepper motor drive ensures consistent plunger displacement and minimizes mechanical hysteresis across repeated cycles.
• Ergonomic, low-center-of-mass housing designed for extended use; weight distribution optimized to reduce wrist fatigue during high-throughput pipetting sessions.
• Dual rotary control interface enables all functions—including volume selection, mode switching (pipette/mix/aspirate), and speed adjustment—without menu navigation or touchscreen interaction.
• Integrated monochrome LCD display mounted directly on the pipette body provides real-time feedback on set volume, current mode, battery status, and error codes—maintaining visual continuity with conventional manual pipette workflows.
• Variable aspiration and dispense speeds allow fine-tuned control over viscous or volatile liquids, reducing bubble formation and improving transfer fidelity for low-volume applications such as qPCR master mix preparation or NGS library normalization.
• Piston assembly components are constructed from autoclavable PEEK and stainless steel, validated for 20 cycles at 121 °C / 20 min / 1 bar without performance degradation—supporting ISO 8655-2 compliance for reusable pipette maintenance.

Sample Compatibility & Compliance

The dPette SCAA-105 is compatible with standard conical tip formats (DNF/UNF) conforming to ISO 8655-3 specifications. It maintains accuracy and repeatability when used with certified low-retention tips, filtered barrier tips, and pre-sterilized consumables. While not classified as a medical device, its design adheres to ISO 8655-1 (general requirements), ISO 8655-2 (volumetric performance), and ISO 8655-5 (testing methods) for piston-operated volumetric apparatus. The device supports audit-ready calibration documentation when paired with an ISO/IEC 17025-accredited analytical balance and DLAB’s calibration utility software—enabling laboratories to fulfill internal quality system requirements under CLIA, CAP, or ISO/IEC 17025 frameworks.

Software & Data Management

Calibration is performed locally using DLAB’s proprietary PC-based calibration assistant, which communicates with the pipette via USB connection. The software guides users through step-by-step gravimetric verification per ISO 8655-6, records calibration date, operator ID, balance serial number, environmental conditions (temperature, humidity), and generates a timestamped PDF report compliant with ALCOA+ principles. All calibration data is stored locally; no cloud upload or external server dependency is required—preserving data sovereignty and meeting GDPR and HIPAA-aligned data governance expectations. Firmware updates are delivered via signed binary packages, ensuring integrity and version traceability.

Applications

The SCAA-105 is routinely deployed in molecular biology labs for precise dispensing of restriction enzymes, ligases, and Taq polymerase into sub-10 µL reaction volumes; in clinical diagnostics for serum dilution series and ELISA plate setup; in pharmaceutical QC for dissolution sample preparation and standard curve generation; and in academic research settings requiring reproducible micro-volume transfers in cell culture media supplementation or CRISPR guide RNA complex formation. Its programmable multi-range capability (0.5–10 µL, 5–50 µL, etc.) allows one instrument to serve multiple assay protocols without hardware reconfiguration—reducing inventory complexity and cross-contamination risk associated with multi-pipette setups.

FAQ

Is the dPette SCAA-105 suitable for use with corrosive or highly viscous liquids?

Yes—when paired with chemically resistant tips and operated within recommended speed settings, it handles 70% glycerol solutions and 1 M NaOH dilutions reliably. However, prolonged exposure to strong oxidizers (e.g., concentrated HNO₃) is not advised.
Does the device support 21 CFR Part 11 compliance?

The pipette itself does not include electronic signature or audit trail functionality; however, its calibration workflow integrates with LIMS or ELN systems that provide Part 11-compliant user authentication and electronic record retention.
Can the SCAA-105 be calibrated in-house without third-party service?

Yes—user-performed calibration is fully supported using any USB-enabled analytical balance with ≥0.01 mg readability and DLAB’s freely distributed calibration software.
What is the expected battery life per full charge?

Under typical usage (200 pipetting cycles/day at medium speed), the battery sustains >8 hours of continuous operation; cycle life exceeds 500 full charges.
Are replacement parts available for long-term maintenance?

DLAB supplies OEM-certified piston seals, O-rings, tip ejectors, and battery modules with documented shelf-life and traceable manufacturing batches—ensuring continued performance alignment with original ISO 8655 validation data.
