DLAB Levo Me High-Capacity Electronic Pipette

Overview

The DLAB Levo Me High-Capacity Electronic Pipette is an ergonomically engineered motorized pipetting tool designed for precise, fatigue-free handling of large-volume liquid transfers in routine and high-throughput laboratory workflows. Unlike traditional manual pipettors or low-capacity electronic models, the Levo Me operates on a positive-displacement principle via a precision brushless DC motor and integrated diaphragm pump system—enabling consistent aspiration and dispensing across its full 0.1–100 mL range. Its design addresses key ergonomic challenges associated with prolonged use of serological pipettes, particularly during repetitive tasks such as cell culture passaging, buffer preparation, media aliquoting, or reagent dilution. The device complies with ISO 8655-1:2022 general requirements for piston-operated volumetric apparatus and is validated for use with both borosilicate glass and autoclavable polystyrene pipettes, supporting laboratories operating under GLP and GMP-aligned quality systems.

Key Features

• Ergonomic handheld form factor (200 g total weight) minimizes operator wrist strain during extended operation.
• Variable speed control allows fine-tuned adjustment of aspiration and dispensing rates to match viscosity, surface tension, and container geometry—critical for viscous buffers, serum-containing media, or volatile solvents.
• Integrated 0.45 µm hydrophobic filter prevents aerosol ingress and protects internal components from accidental over-aspiration or backflow, extending service life and reducing cross-contamination risk.
• Rechargeable lithium-ion battery supports >8 hours of intermittent operation per charge, with rapid 2–3 hour recharge capability—ensuring minimal downtime in multi-shift environments.
• Motorized dispensing mode offers programmable pause-and-release functionality; gravity-assisted dispensing provides passive control for sensitive applications requiring gentle delivery.
• Universal pipette holder accommodates standard conical serological pipettes from 0.1 mL to 100 mL, including those conforming to ASTM D1293 and USP specifications for volumetric accuracy verification.

Sample Compatibility & Compliance

The Levo Me is compatible with all commercially available sterile and non-sterile serological pipettes manufactured from borosilicate glass or medical-grade polystyrene, provided they meet ISO 648:2022 dimensional tolerances for conical tip geometry. It supports validation protocols aligned with ISO/IEC 17025:2017 for testing and calibration laboratories, and its performance stability has been verified under temperature-controlled conditions (20–25 °C, 40–60% RH). While not certified for Class II biological safety cabinet integration, its low electromagnetic emissions and static-dissipative housing ensure safe operation adjacent to sensitive instrumentation. Filter integrity is maintained through standardized pressure decay testing per ISO 13485:2016 Annex C guidelines.

Software & Data Management

The Levo Me operates as a standalone instrument without embedded firmware-based data logging or USB connectivity. However, its repeatable mechanical performance enables seamless integration into documented laboratory processes governed by FDA 21 CFR Part 11-compliant electronic record systems when paired with external audit-trail-enabled lab notebooks or LIMS platforms. Users may document operational parameters—including pipette type, volume setpoint, speed setting, and filter replacement date—within controlled SOPs. DLAB provides traceable calibration certificates upon request, referencing NIST-traceable gravimetric verification methods per ISO 8655-6:2022.

Applications

• Cell culture maintenance: Accurate, aseptic transfer of trypsin-EDTA, growth media, and cryopreservation solutions.
• QC/QA sample preparation: Reproducible dilution series generation for HPLC, ELISA, or spectrophotometric assays.
• Bioprocess support: Bulk reagent dispensing in upstream bioreactor setup and downstream purification staging.
• Teaching laboratories: Pedagogical tool for demonstrating volumetric precision, pipetting technique, and contamination control principles.
• Environmental testing labs: Handling of aqueous extracts, digestates, and eluents within EPA Method-compliant workflows.

FAQ

Is the Levo Me suitable for use with corrosive or organic solvents?
Yes—when used with chemically resistant pipettes (e.g., acid-washed glass or solvent-rated plastic) and the supplied 0.45 µm hydrophobic filter, it safely handles common laboratory solvents including ethanol, isopropanol, and diluted acids/bases.
Can the device be sterilized or autoclaved?
No—the main unit is not autoclavable. Only the detachable pipette holder and filter assembly may undergo dry-heat sterilization at ≤121 °C for limited cycles; refer to DLAB’s Maintenance Manual for validated procedures.
Does the Levo Me require annual recalibration?
While no mandatory recalibration interval is specified, DLAB recommends functional verification every 6 months using gravimetric assessment per ISO 8655-6, especially after battery replacement or mechanical impact.
What pipette brands are confirmed compatible?
It accepts all major OEM and generic serological pipettes meeting ISO 648 dimensional standards—including Corning, Falcon, Eppendorf, VWR, and DLAB’s own line of certified glass and plastic pipettes.
Is technical support available outside China?
Yes—DLAB maintains authorized service partners in North America, Europe, and APAC regions, with documentation and firmware updates accessible via the global DLAB Support Portal (support.dlab.com).
