Overview
The DLAB Standard Mini Pipette is a precision-engineered single-channel manual pipette designed for high-frequency, low-volume liquid handling in clinical diagnostics, molecular biology, and routine laboratory workflows. Built on the principles of positive displacement and air-cushion aspiration/dispensing, it delivers consistent volumetric accuracy and repeatability across its calibrated range of 10–200 µL. Its compact form factor—optimized through iterative ergonomic assessment—reduces operator fatigue during extended use, particularly in high-throughput environments such as IVD kit assembly lines, QC testing labs, and point-of-care assay preparation stations. The pipette conforms to ISO 8655-2 (2022) for gravimetric performance verification and is factory-calibrated per ISO 8655-5, with traceable documentation available upon request.
Key Features
- Ergonomic lightweight design (≤95 g) with balanced center-of-gravity positioning to minimize thumb strain and wrist deviation during repetitive pipetting cycles.
- Compact body profile (135 mm height × 32 mm max diameter) enables unobstructed access to narrow tube racks, microtiter plates, and diagnostic cartridge wells.
- Color-coded volume range identification per ISO 8655-1: each model features a distinct PANTONE or RAL hue applied to the plunger cap and volume adjustment ring—ensuring rapid visual differentiation in multi-pipette workspaces.
- High-precision stainless-steel tip ejector mechanism with dual-stage resistance feedback, providing tactile confirmation of full ejection without excessive force.
- Chemically resistant polypropylene housing and autoclavable (121°C, 20 min) upper body components compatible with standard lab decontamination protocols.
- Adjustable volume lock prevents accidental setting drift; fine-tuning knob offers ±0.1 µL resolution within the 10–200 µL range.
Sample Compatibility & Compliance
The DLAB Standard Mini Pipette is validated for use with standard conical 200 µL universal-fit pipette tips (including filtered and low-retention variants). It maintains metrological integrity when dispensing aqueous buffers (PBS, Tris-HCl), glycerol-diluted reagents (up to 40% v/v), and ethanol-based wash solutions. All models comply with ISO 13485:2016 for medical device manufacturing environments and support GLP/GMP documentation requirements through optional calibration certificates (ISO/IEC 17025 accredited). Device construction adheres to RoHS 2011/65/EU and REACH (EC 1907/2006) material restrictions.
Software & Data Management
As a manually operated instrument, the Standard Mini Pipette does not incorporate embedded electronics or connectivity interfaces. However, it integrates seamlessly into digitally managed workflows via third-party lab information systems (LIMS) and electronic lab notebooks (ELN). Calibration records—including date, technician ID, gravimetric test results, and uncertainty budgets—can be archived in accordance with FDA 21 CFR Part 11 when paired with compliant document management platforms. DLAB provides editable calibration log templates (Excel and PDF) aligned with ISO/IEC 17025 reporting conventions.
Applications
- Preparation of IVD assay reagent kits requiring precise sub-200 µL aliquots (e.g., enzyme conjugates, calibrators, controls).
- Serial dilution series in ELISA, lateral flow test development, and nucleic acid amplification setup.
- Cell culture media supplementation and transfection reagent dispensing in adherent and suspension formats.
- QC release testing of pharmaceutical excipients and biologics where volumetric consistency directly impacts potency assay outcomes.
- Academic teaching laboratories emphasizing fundamental pipetting technique training under ISO 8655 competency frameworks.
FAQ
Is this pipette suitable for viscous or volatile liquids?
It is optimized for aqueous and moderately viscous solutions (up to 10 mPa·s at 20°C); for highly viscous (>20 mPa·s), dense, or volatile solvents, reverse pipetting or positive displacement pipettes are recommended.
Can the color coding be customized beyond the standard PANTONE/ RAL options?
Yes—DLAB supports OEM color matching against customer-provided physical swatches or digital color values (sRGB, HEX) for volume-specific identification in regulated manufacturing settings.
What is the recommended recalibration interval?
Annual calibration is advised under normal usage (≤200 actuations/day); more frequent verification (quarterly) is required in GMP environments or after mechanical impact events.
Are replacement parts available separately?
Yes—seals, springs, plungers, and tip cones are stocked globally and supplied with serial-matched calibration data sheets.
Does the pipette meet ISO 8655 certification requirements out-of-the-box?
Each unit ships with a factory calibration certificate referencing ISO 8655-2:2022 test conditions, including temperature (22 ± 2°C), humidity (45–65% RH), and gravimetric methodology using certified Class E2 weights and distilled water (density 0.99716 g/mL at 22°C).
