Overview
The BRAND eLINE Plus Electronic Pipette Aid 26300 is a precision-engineered, cordless electronic pipetting assistant designed for high-reproducibility liquid handling across academic, clinical, and industrial laboratories. Based on brushless DC motor actuation and closed-loop airflow control, the device delivers consistent aspiration and dispensing performance across its full operational range of 0.1–200 mL—compatible with both glass and polypropylene serological pipettes. Its core architecture integrates ergonomic design principles with regulatory-grade fluid containment: a certified 0.2 µm hydrophobic membrane prevents aerosol ingress, while an automatic calibration valve ensures pressure stability and eliminates cross-contamination risk during repeated use. The system operates without mechanical pistons or vacuum reservoirs, relying instead on real-time airflow modulation to maintain linear response across variable pipette diameters and viscosities.
Key Features
- Ergonomic lightweight construction (190 g) with balanced center-of-mass distribution—optimized for extended daily use without operator fatigue.
- Dual-button continuous speed control: independent adjustment of aspiration and dispensing rates via tactile force-sensitive actuators—enabling fine-grained velocity tuning from gentle layering to rapid bulk transfer.
- Brushless DC motor with thermal overload protection: achieves full aspiration of a 50 mL pipette in ≤10 s at maximum setting, operating at sound pressure levels <45 dB(A) under standard lab conditions.
- Integrated intelligent battery management: rechargeable Li-ion pack supports up to 8 hours of continuous operation; LED status indicator provides two-hour advance low-battery warning before shutdown.
- Single-hand operability: all functions—including discharge mode selection (gravity drain vs. motor-assisted blow-out), speed adjustment, and power activation—are accessible without repositioning the hand or compromising pipette grip.
- Sealed internal pathway with auto-resetting calibration valve and replaceable 0.2 µm PTFE membrane—validated per ISO 8549 for microbial retention and compliant with biosafety Level 2 (BSL-2) containment protocols.
Sample Compatibility & Compliance
The eLINE Plus 26300 accommodates standard conical-tip serological pipettes (1–200 mL) and volumetric transfer pipettes (0.1–10 mL), including those manufactured from borosilicate glass, polystyrene, and polypropylene. It is validated for use with aqueous buffers, cell culture media, diluted acids/bases (pH 2–12), and ethanol/water mixtures (<30% v/v). The device conforms to CE marking requirements under the EU Medical Device Regulation (MDR 2017/745) Annex I essential requirements, electromagnetic compatibility per EN 61000-6-3, and safety standards EN 61010-1. Its filtration system meets ISO 8549:2021 criteria for aerosol retention efficiency and is routinely verified during GLP-compliant instrument qualification (IQ/OQ/PQ).
Software & Data Management
As a standalone manual pipetting aid, the eLINE Plus 26300 does not incorporate embedded firmware, Bluetooth connectivity, or digital data logging. However, it supports traceability-driven workflows through physical documentation: each unit carries a unique serial number laser-engraved on the housing, enabling linkage to laboratory equipment logs, maintenance records, and calibration certificates. Optional accessories—including sterile-filtered battery caps, autoclavable charging docks (Cat. No. 26301), and wall-mountable holders (Cat. No. 26302)—are supplied with individual CoA (Certificate of Analysis) and bioburden test reports. For regulated environments requiring audit trails, integration into electronic lab notebooks (ELNs) is achieved via manual entry of usage logs aligned with 21 CFR Part 11–compliant signature workflows.
Applications
This pipette aid is routinely deployed in applications demanding repeatability, sterility assurance, and operator safety: preparation of cell culture inocula and transfection reagents; serial dilution of ELISA standards and PCR master mixes; volumetric transfer in HPLC sample preparation and dissolution testing; and quantitative spiking in food allergen and environmental toxin analysis. Its gravity-dispense mode ensures laminar outflow for density-layered centrifugation protocols, while motor-assisted blow-out enables complete recovery of viscous samples such as glycerol stocks or serum-containing media. In clinical microbiology labs, it supports CLSI-recommended broth microdilution assays where precise 100 µL transfers directly impact MIC endpoint determination.
FAQ
Is the eLINE Plus 26300 compatible with positive-displacement pipettes?
No—it is engineered exclusively for air-cushion (volume-calibrated) serological and volumetric pipettes.
Can the 0.2 µm filter be sterilized by autoclaving?
The integrated PTFE membrane is not autoclavable; replacement filters (Cat. No. 26303) are supplied gamma-irradiated and individually wrapped.
What is the recommended recalibration interval?
BRAND recommends functional verification before each shift in GMP environments; full calibration is performed annually using gravimetric methods per ISO 8655-9.
Does the device support external power during operation?
No—the unit operates solely on its internal battery; charging requires disconnection from pipette use.
Are spare parts available for field service?
Yes—battery assemblies, membrane cartridges, and ergonomic grips are stocked globally with documented shelf life and lot traceability.
