Overview
The DLAB dPette+ is an advanced electronic single-channel pipette engineered for precision liquid handling in regulated and high-throughput laboratory environments. Unlike conventional manual or basic electronic pipettes, the dPette+ integrates a high-resolution stepper motor, programmable multi-mode operation, and full ergonomic design—delivering reproducible volumetric delivery across four interchangeable volume ranges (0.5–10 μL, 5–50 μL, 30–300 μL, and 100–1000 μL). Its operating principle relies on controlled motor-driven piston displacement within a sealed air-displacement system, ensuring consistent aspiration and dispensing kinetics independent of user technique. Designed to meet ISO 8655-2:2022 requirements for pipette performance verification, the dPette+ supports traceable calibration workflows and complies with GLP/GMP-aligned documentation practices when used with certified analytical balances and USB-connected calibration software.
Key Features
- Four preconfigured volume ranges with seamless switching via dual rotary controls—no tool required
- High-precision stepper motor delivering consistent plunger travel and minimized hysteresis across all ranges
- Ergonomic, low-mass body (≤125 g) with balanced center-of-gravity and textured grip surface for reduced operator fatigue during extended use
- Adjustable aspiration and dispensing speeds (3 levels per mode) to accommodate viscous, volatile, or foaming liquids
- Integrated rechargeable lithium-ion battery supporting ≥10,000 pipetting cycles per charge; compatible with both cradle and direct USB-C charging
- Large backlit LCD display positioned at the pipette’s natural line-of-sight angle—mirroring manual pipette interface logic for rapid operator transition
- Onboard programmable modes: Standard Aspirate/Dispense, Continuous Mixing, Serial Dispensing, and 1:1 Dilution
- Piston assembly components rated for autoclaving at 121 °C / 20 min (ISO 17664-compliant sterilization)
- Self-calibration capability using any USB-enabled analytical balance (≥0.01 mg resolution); calibration data logged with timestamp and operator ID
Sample Compatibility & Compliance
The dPette+ is validated for use with aqueous buffers, cell culture media, enzymatic reagents, and common organic solvents (e.g., ethanol, isopropanol, acetonitrile) within its specified volume ranges. All wetted parts—including the O-rings, piston seal, and tip ejector—are chemically resistant to standard lab-grade solvents and non-corrosive to stainless steel internals. The device conforms to IEC 61000-4 electromagnetic compatibility standards and carries CE marking under the EU Medical Device Regulation (MDR) Annex XVI classification for non-invasive laboratory instrumentation. Calibration reports generated via the dPette+ software comply with FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with audit-trail enabled systems.
Software & Data Management
DLAB provides the dPette+ Configuration Utility—a Windows-based desktop application enabling firmware updates, parameter backup/restore, and calibration report generation in PDF format. Each calibration event is time-stamped, digitally signed, and includes raw gravimetric data (mass before/after transfer), calculated volume, accuracy and precision metrics (CV%), and environmental conditions (ambient temperature/humidity if logged externally). Exported reports support CSV and XML formats for integration into LIMS or ELN platforms. No cloud dependency: all configuration and calibration data remain local unless explicitly exported by the user.
Applications
- qPCR and digital PCR setup requiring sub-microliter accuracy in master mix preparation
- Cell-based assays involving serial dilutions of growth factors or inhibitors across multi-well plates
- Quality control testing in pharmaceutical manufacturing (e.g., USP analytical instrument qualification)
- Genomic library preparation where low-volume fragmentation and adapter ligation demand high repeatability
- Calibration of reference standards in metrology labs adhering to ISO/IEC 17025
- Teaching laboratories requiring intuitive yet technically rigorous tools for pipetting competency assessment
FAQ
Is the dPette+ suitable for ISO/IEC 17025-accredited testing laboratories?
Yes—the device supports full traceability through user-defined calibration logs, meets ISO 8655 accuracy specifications, and allows integration with accredited balance systems for documented uncertainty budgets.
Can the dPette+ be calibrated without sending it to a service center?
Yes—self-calibration is fully supported using any USB-connected analytical balance meeting minimum resolution requirements (0.01 mg). No third-party intervention is required.
Does the dPette+ support variable tip ejection force?
No—tip ejection is standardized for reliable release across universal low-retention tips; however, the mechanical ejection mechanism is designed to minimize tip deformation and residual carryover.
What is the recommended recalibration interval?
DLAB recommends recalibration every 6 months for routine use, or after 10,000 operations—whichever occurs first—as aligned with ISO 8655-5:2022 guidance for electronic pipettes.
Are replacement parts available globally?
Yes—DLAB maintains an international spare parts catalog including piston assemblies, seals, battery modules, and display housings, with lead times under 10 business days from regional distribution hubs in Europe, North America, and APAC.
