Overview
The DLAB dPette+ Electric 8-Channel Pipettor is a precision-engineered liquid handling instrument designed for high-throughput, reproducible multichannel pipetting in molecular biology, clinical diagnostics, drug discovery, and quality control laboratories. Operating on the principle of positive displacement via motor-driven piston actuation, it eliminates operator-induced variability inherent in manual pipetting while maintaining full compatibility with standard ANSI/SLAS-format 96-well and 384-well microplates. Its modular architecture integrates a brushless stepper motor, high-resolution optical encoder feedback loop, and thermally stable polymer housing to ensure consistent plunger travel across all eight channels—critical for applications demanding inter-well uniformity such as ELISA, qPCR setup, cell culture passaging, and library preparation.
Key Features
- Three programmable volume ranges: 0.5–10 µL, 10–100 µL, and 30–300 µL—with selectable increments of 0.01 µL, 0.1 µL, and 1 µL respectively—enabling flexible assay design without hardware switching.
- Ergonomic, low-center-of-gravity chassis with balanced weight distribution (≤125 g) reduces wrist fatigue during extended use; curvature optimized per ISO 9241-5 human factors guidelines.
- Integrated 2.8-inch monochrome LCD display mounted directly on the pipettor body—mirroring manual pipette interaction logic—to provide real-time volume setting, mode status, battery level, and error codes without external software dependency.
- Dual concentric rotary controls allow one-handed parameter adjustment and function selection: outer knob for volume, inner knob for mode (aspirate/dispense, continuous dispensing, or mixing).
- Adjustable aspiration and dispense speeds (3 levels each) accommodate viscous solutions (e.g., glycerol-containing buffers), volatile solvents, or foaming reagents while minimizing carryover and tip dripping.
- Autoclavable piston assembly (stainless steel shaft + PTFE-coated seal) validated for ≥20 cycles at 121 °C / 20 min / 1 bar per ISO 17665-1, supporting GLP/GMP-compliant workflows requiring routine decontamination.
Sample Compatibility & Compliance
The dPette+ supports universal compatibility with OEM and third-party low-retention, filtered, and sterile-filtered tips meeting ISO 8655-3 dimensional tolerances. It complies with ISO 8655-2:2022 for gravimetric performance evaluation—including accuracy (±2.00% at 10 µL), precision (CV ≤1.0% at 10 µL), and linearity across its full operating range. All specifications are traceable to NIST-certified reference standards. The device meets IEC 61326-1 (EMC) and IEC 61010-1 (safety) requirements for laboratory electrical equipment. While not FDA 21 CFR Part 11–certified out-of-the-box, audit-ready calibration logs (including date, operator ID, and deviation values) can be exported via USB for internal SOP documentation.
Software & Data Management
Calibration is performed locally using only a USB-connected analytical balance (≥0.01 mg readability) and included PC software (Windows/macOS compatible). The application guides users through step-by-step ISO 8655-2–compliant procedures—including multi-point gravimetric checks—and generates PDF reports with metadata (timestamp, balance ID, environmental conditions). No cloud upload or subscription is required. Firmware updates are delivered via signed .bin files over USB; version history and checksum validation ensure integrity. Audit trails record all calibration events, parameter changes, and system errors—supporting internal quality audits under ISO/IEC 17025 or CLIA frameworks.
Applications
- High-fidelity nucleic acid quantification and normalization prior to NGS library construction.
- Parallel dispensing of master mixes into 96-well PCR plates with ≤1.0% inter-channel CV.
- Serial dilution series generation with automated repeat dispensing (up to 99×) and mixing steps.
- Cell seeding consistency improvement in stem cell or primary culture expansion protocols.
- QC release testing of biologics where volumetric accuracy directly impacts potency assay outcomes.
FAQ
Is the dPette+ compatible with non-DLAB tips?
Yes—it accepts any tip conforming to ISO 8655-3 geometry specifications, including universal-fit low-binding and filter tips from major global suppliers.
Can calibration data be exported for regulatory submission?
Yes: PDF calibration certificates include operator name, balance serial number, ambient temperature/humidity, raw gravimetric data, and pass/fail status against ISO 8655-2 acceptance criteria.
What maintenance is required beyond autoclaving?
Annual lubrication of the piston drive mechanism using DLAB-specified silicone grease (part #LUB-01) is recommended; no user-serviceable electronics require replacement within the 3-year warranty period.
Does the device support variable tip ejection force?
No—tip ejection is standardized at 12 N to ensure reliable release across tip brands while preventing damage to rack inserts or plate edges.
How long does a full charge last under typical usage?
Approximately 12 hours of continuous operation (≥2,000 pipetting cycles) at medium speed; battery health monitoring alerts users at ≤15% remaining capacity.
