ROCKER Lafil200-BioDolphin Vacuum Liquid Aspiration System

Overview

The ROCKER Lafil200-BioDolphin Vacuum Liquid Aspiration System is an integrated, benchtop-grade vacuum aspiration platform engineered for high-efficiency, contamination-controlled liquid removal in cell culture, molecular biology, and routine laboratory workflows. Unlike modular vacuum setups requiring separate pumps, bottles, and controllers, the Lafil200-BioDolphin integrates a brushless DC vacuum source, ergonomic handheld controller, and 4 L polypropylene waste reservoir into a single compact unit—reducing footprint by up to 50% compared to traditional configurations. Its operation relies on regulated negative pressure generation (down to 213 mbar absolute) to drive controlled aspiration through disposable or autoclavable tip adapters, ensuring consistent flow dynamics (17 mL/sec peak rate) without cavitation or pulsation. Designed for daily use in GLP-compliant environments, the system meets ISO 13485-aligned manufacturing standards and supports traceable operation via mechanical lock-out functionality and physical overflow safeguards.

Key Features

• All-in-one architecture: Integrated vacuum generator, controller, and waste bottle eliminate inter-component tubing, reducing leak points and setup time.
• Ergonomic handheld controller with tactile Lock button: Enables hands-free continuous aspiration during prolonged procedures; designed for extended grip stability and reduced operator fatigue.
• Single-hand tip ejection mechanism: Patented eight-prong POM tip adapter allows rapid, tool-free tip removal without compromising sterility or requiring secondary instruments.
• Dual-layer safety system: Includes (1) float-ball overflow protection that automatically cuts vacuum when liquid reaches critical level, and (2) recessed, rim-secured waste bottle platform preventing accidental tipping during handling.
• Steam-sterilizable components: All fluid-path materials—including POM adapters, SS304 metal tubing, and PES-compatible waste bottle—are validated for autoclaving at 121°C for 20 minutes per ISO 17665-1.
• Modular accessory interface: Quick-connect bayonet mount enables tool-less swapping between single- and multi-prong adapters, glass pipette holders, and custom-length suction tips (50–150 mm).
• Noise-optimized motor design: Brushless DC drive maintains <55 dB(A) acoustic emission at 1 m distance—suitable for open-lab and biosafety cabinet installations.

Sample Compatibility & Compliance

The Lafil200-BioDolphin accommodates a broad range of liquid types encountered in life science laboratories, including aqueous buffers, serum-containing media, enzymatic digestates, and low-viscosity reagents (up to 10 cP). It is not intended for viscous, particulate-laden, or corrosive solvents (e.g., acetone, chloroform). Waste bottle compatibility extends to standard 4 L PP containers and optional 3.5 L serum bottles (Cat. No. 197200-53), both certified for Class I biological containment per EN 14122-3. Regulatory compliance includes CE marking under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), RoHS 2011/65/EU conformance, and IP41 ingress protection for dust and vertically falling water droplets. The system supports audit-ready documentation workflows in accordance with FDA 21 CFR Part 11 when used with external logbook systems.

Software & Data Management

As a hardware-centric aspiration platform, the Lafil200-BioDolphin operates without embedded firmware or digital connectivity—ensuring electromagnetic immunity in sensitive instrumentation zones (e.g., near mass spectrometers or electrophysiology rigs). All operational parameters are mechanically governed: vacuum level is fixed at 213 mbar, flow rate is stabilized via calibrated orifice design, and runtime is user-determined via manual trigger actuation. This analog architecture eliminates cybersecurity risks, firmware obsolescence, and calibration drift associated with microprocessor-dependent systems. For laboratories requiring procedural traceability, the Lock function provides a repeatable mechanical state, while physical maintenance logs (e.g., autoclave cycles, tip adapter replacements) can be recorded manually in lab notebooks compliant with ISO/IEC 17025 Section 7.10.

Applications

• Cell culture maintenance: Rapid aspiration of spent media from T-flasks, roller bottles, and multi-well plates without cross-contamination risk.
• Biosafety cabinet workflows: Low-noise, compact operation enables seamless integration into Class II A2 and B2 cabinets without airflow disruption.
• Histology and tissue processing: Controlled removal of fixatives and staining solutions from specimen containers.
• Quality control labs: Reproducible liquid decanting in raw material testing and environmental sample preparation.
• Teaching laboratories: Robust construction and intuitive interface support high-throughput student training in aseptic technique.

FAQ

Can the Lafil200-BioDolphin be used inside a CO₂ incubator?
No—the unit is rated for ambient laboratory conditions only (10–40°C, ≤80% RH non-condensing) and lacks temperature-stabilized electronics or humidity-resistant seals required for incubator environments.
Is the 4 L waste bottle certified for UN-rated transport?
No—while chemically compatible with common biological waste streams, the PP bottle is not UN-certified for hazardous material shipping; it is intended solely for on-site collection and disposal.
What is the expected service life of the vacuum pump under continuous operation?
The brushless DC motor is rated for ≥20,000 hours MTBF under intermittent duty cycles (≤30 min ON / 10 min OFF); continuous operation beyond 45 minutes requires active cooling and is not recommended.
Are replacement tip adapters available as standalone parts?
Yes—ROCKER supplies individual adapters under part numbers 199100-00 (BioDolphin kit), 197200-53 (4 L bottle), and 197203-01 (complete system), all with full technical datasheets and sterilization validation reports.
Does the system include a vacuum gauge or pressure readout?
No—it operates at a fixed vacuum setpoint (213 mbar) verified during factory calibration; no real-time monitoring interface is provided, aligning with ISO 8573-1 purity class 4 requirements for oil-free compressed air systems.
