Overview
The DLAB 7050912030 is a precision-engineered mini single-channel manual pipette designed for high-frequency, low-volume liquid handling tasks in clinical diagnostics, molecular biology, and point-of-care assay development. Based on the air-displacement principle, this pipette delivers consistent volumetric accuracy across its full 30–300 µL range through a thermally stable piston system and optimized internal air column dynamics. Its compact form factor—measuring under 140 mm in length and weighing less than 85 g—minimizes hand fatigue during extended use and enables precise operation in confined workspaces such as microtiter plate racks, biosafety cabinets, and integrated IVD instrument modules. Unlike full-size pipettes, the 7050912030 features a shortened plunger stroke and reduced activation force (≤1.8 N at full volume), making it particularly suitable for users with repetitive strain concerns or those performing rapid serial dilutions in diagnostic kit assembly lines.
Key Features
- Ergonomic ultra-compact design: Optimized grip geometry and center-of-mass positioning reduce wrist torque and improve control during repeated aspiration/dispense cycles.
- Color-coded volume setting ring (purple) for rapid visual identification of 300 µL capacity—part of DLAB’s standardized ISO 8655-compliant color-coding system.
- High-precision adjustable volume mechanism with dual-scale graduation (µL and %) and tactile click-stop feedback at each 10 µL increment.
- Chemically resistant PTFE-coated piston and autoclavable (121°C, 20 min) upper body components ensure long-term reliability in reagent-intensive environments.
- Interchangeable tip cone compatible with all major manufacturers’ 200–300 µL conical tips meeting ISO 8655-2 dimensional tolerances.
- No-tool calibration capability via recessed adjustment screw—enabling on-site traceable recalibration per laboratory quality management procedures (e.g., ISO/IEC 17025).
Sample Compatibility & Compliance
The DLAB 7050912030 is validated for aqueous solutions, buffers, serum, plasma, and common molecular biology reagents (e.g., PCR master mixes, restriction enzyme cocktails). It is not recommended for highly viscous (≥100 mPa·s), volatile (e.g., acetone, chloroform), or corrosive liquids (e.g., concentrated acids/bases) without tip immersion depth optimization and pre-wetting protocols. The pipette conforms to ISO 8655-1:2022 (General requirements) and ISO 8655-5:2022 (Testing methods for manual pipettes), with factory-certified performance data available upon request. All units undergo individual gravimetric verification per ISO 8655-6 prior to shipment. For regulated environments—including CLIA-certified labs, ISO 13485 medical device manufacturing, and GMP-compliant IVD production—the device supports integration into equipment qualification protocols (IQ/OQ/PQ) and meets documentation requirements for traceability and metrological control.
Software & Data Management
As a manually operated mechanical device, the DLAB 7050912030 does not incorporate embedded electronics or firmware. However, its design fully supports digital workflow integration: volume settings are documented in electronic lab notebooks (ELNs) via standardized metadata fields; calibration records align with 21 CFR Part 11 audit trail requirements when managed within validated LIMS platforms; and usage logs (e.g., tip batch tracking, operator ID, calibration date) can be synchronized with QMS systems using DLAB’s optional calibration certificate templates (PDF/A-1b compliant). Traceable calibration certificates include uncertainty budgets calculated per GUM (JCGM 100:2008) and reference to NIM-traceable mass standards.
Applications
- IVD kit assembly: Precise dispensing of capture antibodies, conjugates, and calibrators into lateral flow strips or microfluidic cartridges.
- Molecular diagnostics: Spotting cDNA libraries, loading qPCR reaction mixtures, and preparing NGS library normalization standards.
- Clinical microbiology: Serial dilution of bacterial suspensions for MIC determination and colony-forming unit (CFU) enumeration.
- Cell culture QC: Adding growth factors, antibiotics, or viability dyes to small-volume cultures in 96-well plates.
- Reference material preparation: Gravimetric dilution of certified reference substances (CRMs) for internal quality control materials.
FAQ
Is the DLAB 7050912030 compliant with ISO 8655?
Yes—each unit is manufactured and tested in accordance with ISO 8655-1, -5, and -6, and ships with a certificate of conformance.
Can this pipette be autoclaved?
The upper body (including plunger, tip cone, and volume adjustment mechanism) is fully autoclavable at 121°C for 20 minutes; the lower body (grip shell) is not autoclavable and must be surface-decontaminated.
What tip types are compatible?
All standard conical 200–300 µL tips complying with ISO 8655-2 dimensional specifications—including DLAB, Eppendorf, Gilson, and Thermo Fisher brands—are mechanically and functionally compatible.
Does it support GLP/GMP documentation requirements?
Yes—calibration certificates include measurement uncertainty, environmental conditions, reference standards used, and technician signature; these meet ALAC and ISO/IEC 17025 reporting criteria for regulated laboratories.
How often should recalibration be performed?
DLAB recommends quarterly verification for routine use; more frequent checks (e.g., daily or per shift) are required in high-throughput diagnostic manufacturing or when handling critical reference standards.
