DLAB EcoVac 2L Compact Vacuum Liquid Aspiration System

Overview

The DLAB EcoVac 2L Compact Vacuum Liquid Aspiration System is an engineered solution for precise, contamination-controlled liquid removal in routine and sensitive laboratory workflows. Designed around a robust brushless DC motor and optimized vacuum circuitry, the system operates on the principle of controlled negative pressure generation to aspirate liquids from culture plates, centrifuge tubes, pipette tips, and other standard labware. Its core architecture prioritizes ergonomic usability, environmental containment, and regulatory-compliant operation—making it suitable for biosafety level 1 and 2 environments, including laminar flow hoods, biosafety cabinets, and benchtop installations where space and noise constraints are critical. With a maximum attainable vacuum of 500 mbar and a rated pumping speed of 15 L/min under ambient air conditions, the EcoVac delivers consistent aspiration performance across variable viscosity and volume scenarios while maintaining low acoustic emission (<52 dB(A)) during continuous operation.

Key Features

• Compact footprint (180 × 240 × 340 mm) enables flexible placement—on benchtops, inside laminar flow cabinets, or beneath work surfaces without obstructing workflow.
• Dual-mode operation: seamless switching between continuous aspiration and manual trigger-based suction via an ergonomically contoured handpiece, reducing operator fatigue during extended use.
• Integrated hydrophobic filter (0.2 µm PTFE membrane) housed within a self-locking, leak-proof collection bottle interface prevents aerosol escape and protects both the pump and laboratory environment from cross-contamination.
• All fluid-path components—including tubing connectors, bottle adapters, and suction nozzles—are constructed from autoclavable materials (e.g., medical-grade polypropylene and silicone), supporting steam sterilization at 121 °C for 20 minutes per ISO 17665-1.
• Vacuum regulation dial with integrated LED indicator allows real-time visual feedback and fine-tuned pressure control across the full 0–500 mbar range—critical for delicate cell monolayer aspiration or viscous media handling.
• Universal adapter set included, enabling compatibility with common consumables such as 15 mL and 50 mL conical tubes, 96-well plates, Petri dishes, and serological pipettes (1–25 mL).

Sample Compatibility & Compliance

The EcoVac supports aspiration of aqueous buffers, cell culture media, supernatants, wash solutions, and diluted reagents. It is not intended for use with organic solvents, strong acids/bases, or high-viscosity fluids (>100 mPa·s) without prior validation. All wetted materials comply with USP Class VI biological safety standards and are free of detectable leachables per ISO 10993-5 cytotoxicity testing. The system meets IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) requirements. While not certified for GLP or GMP environments out-of-the-box, its design supports audit-ready documentation—including vacuum log export (via optional RS-232/USB interface), user-accessible calibration records, and traceable sterilization logs when integrated into validated lab management systems.

Software & Data Management

The EcoVac operates as a standalone hardware platform with no embedded firmware or cloud connectivity. However, its analog vacuum regulation interface and optional digital output module (sold separately) allow integration with third-party lab information management systems (LIMS) or electronic lab notebooks (ELN) via standard serial protocols. The LED vacuum indicator provides immediate visual status confirmation without requiring software interpretation—enhancing operational reliability in regulated settings where software qualification burdens must be minimized. For laboratories operating under FDA 21 CFR Part 11 requirements, the system can be operated in conjunction with validated external data acquisition tools that enforce electronic signature, audit trail, and role-based access controls.

Applications

• Cell culture maintenance: gentle removal of spent media from adherent and suspension cultures without disturbing monolayers.
• Molecular biology workflows: aspiration of ethanol washes, gel electrophoresis buffer, and PCR plate supernatants.
• Clinical diagnostics: safe handling of patient-derived samples in pre-analytical processing steps under BSL-2 containment.
• Quality control labs: standardized liquid decanting during raw material inspection and stability testing preparations.
• Teaching laboratories: durable, low-maintenance equipment for undergraduate and technician training in aseptic technique and liquid handling fundamentals.

FAQ

Can the EcoVac be used inside a biosafety cabinet?
Yes—the unit’s compact dimensions, low heat dissipation, and absence of exhaust venting make it compatible with Class II A2 and B2 biosafety cabinets when placed upstream of the work surface airflow.
Is the collection bottle autoclavable?
Yes—the standard 2 L polypropylene collection bottle and all associated fluid-path accessories are rated for repeated autoclaving at 121 °C, 15 psi, for 20 minutes.
What maintenance is required for long-term reliability?
Routine maintenance includes periodic replacement of the hydrophobic filter (recommended every 6 months or after 200 hours of cumulative use) and inspection of O-rings and tubing for signs of degradation.
Does the system support vacuum monitoring and logging?
The base model features an analog vacuum dial with LED indication; digital vacuum logging requires the optional RS-232/USB interface module and compatible host software.
Are spare parts and service available outside China?
DLAB maintains authorized distribution and technical support networks across North America, EMEA, and APAC regions, with local inventory of consumables, filters, and replacement motors.
