Overview
The DLAB High-Performance Mini Single-Channel Manual Pipette is an ergonomically engineered liquid handling tool designed for precision volumetric transfer in high-throughput laboratory environments. Based on the fundamental principle of air displacement, this pipette delivers consistent aspiration and dispensing performance across its calibrated volume range of 25–300 µL. Its compact form factor—measuring under 140 mm in height and weighing less than 85 g—reduces operator fatigue during repetitive tasks while maintaining full mechanical accuracy and reproducibility. The device complies with ISO 8655-2:2022 (Piston-operated volumetric apparatus — Part 2: Piston pipettes) for metrological performance and is validated for use in applications requiring traceable calibration under GLP and ISO/IEC 17025 frameworks.
Key Features
- Ergonomic low-force plunger mechanism: Requires ≤ 1.2 N activation force at maximum volume, minimizing thumb strain during extended use.
- Ultra-compact housing: Optimized footprint and center-of-gravity positioning enhance control during fine-tip alignment and multi-well plate work.
- Two-stage volume adjustment: Coarse and fine-tuning dials enable precise, tactile volume setting without tools or disassembly.
- Chemical-resistant polymer construction: Housing and internal components resist degradation from common solvents including ethanol, isopropanol, and diluted acids/bases.
- Interchangeable autoclavable lower assembly: Fully steam-sterilizable (121 °C, 20 min) without compromising seal integrity or calibration stability.
- Color-coded volume indicators: Integrated visual cues aligned with international pipette color standards (e.g., orange for 50 µL, blue for 100 µL) support rapid identification in shared lab environments.
Sample Compatibility & Compliance
This pipette is compatible with standard conical polypropylene pipette tips conforming to ISO 8655-5:2022 dimensional specifications—including both universal-fit and low-retention variants. It supports aqueous solutions, buffers, cell suspensions, serum, plasma, and most diagnostic reagents used in IVD workflows. The device meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and its calibration documentation supports audit readiness for ISO 13485-certified medical device manufacturing facilities. Traceable factory calibration certificates (NIST-traceable reference standards) are provided with each unit.
Software & Data Management
As a manual pipette, this instrument operates independently of software control; however, it integrates seamlessly into digitally managed workflows via optional DLAB PipetteLog™ companion software (sold separately). When paired with a certified calibration station, PipetteLog™ enables electronic recordkeeping of usage logs, maintenance history, calibration due dates, and user-specific settings. All data exports comply with FDA 21 CFR Part 11 requirements for electronic signatures and audit trails. Calibration reports include uncertainty budgets per ISO/IEC 17025 Annex A.3 and support GxP-aligned documentation practices.
Applications
- Quantitative sample preparation for ELISA, PCR setup, and nucleic acid quantification workflows.
- Reagent dispensing in clinical diagnostics laboratories performing point-of-care test development and validation.
- Cell culture passaging and media supplementation where minimal dead volume and tip-to-tip consistency are critical.
- Quality control testing of in vitro diagnostic kits, including linearity verification and repeatability assessment per CLSI EP10-A3 guidelines.
- Academic research requiring high-reproducibility micro-volume transfers in biochemistry, molecular biology, and pharmacology labs.
FAQ
Is this pipette suitable for viscous or volatile liquids?
Yes—when used with positive-displacement tips or low-retention filter tips, it achieves improved accuracy for glycerol-containing solutions (up to 40% v/v) and ethanol-based reagents. For highly volatile solvents, pre-wetting and slow aspiration/dispense protocols are recommended.
What calibration intervals does DLAB recommend?
Annual recalibration is advised for routine use; however, laboratories operating under ISO/IEC 17025 or CLIA requirements may implement risk-based frequency (e.g., quarterly for high-use units), documented in their internal SOPs.
Can the color coding be matched to existing lab-wide pipette systems?
Yes—custom Pantone (PMS) and RAL color options are available directly through DLAB’s OEM service channel, ensuring visual consistency across multi-brand pipette fleets.
Does the pipette include a certificate of conformity?
Each unit ships with a manufacturer’s Declaration of Conformity (DoC) and a factory calibration report referencing ISO 8655-2:2022 test parameters, including gravimetric accuracy and precision at three volume points (10%, 50%, and 100% of nominal range).
